Dean Adams

BCB Faculty Member in the EEOB Department

Education: Ph.D., SUNY at Stony Brook, 1999

Research Interests:

  • Comparative evolutionary biology; micro- and macroevolutionary morphology; theory and analytical methods in evolution; herpetology; morphometrics (statistical shape analysis).
  • Mathematical Biology, Computational Modeling, Computational Systems Biology

Description: Our research focuses on the evolution of the multivariate phenotype. We are interested in understanding micro- and macroevolutionary patterns of phenotypic diversification, and the historical and ecological processes that are responsible for them. We use a comparative evolutionary framework to attain these goals, directing our empirical work towards vertebrates, with an emphasis on plethodontid salamanders. Our theoretical research focuses on the development of new evolutionary tools and analytical methods for assessing biological patterns and processes. Understanding the evolution of multi-dimensional traits (such as shape) is complex, and considerable effort is required to properly merge the mathematical properties of such traits with current evolutionary theory. Current theoretical work emphasizes the development of analytical approaches for evaluating macroevolutionary trends of phenotypic diversification. Specifically, we are developing approaches for characterizing the tempo and mode of evolution for high-dimensional complex traits in a phylogenetic context.

*William Beavis

BCB Faculty Member in the Agronomy Department

Education: Ph.D., 1986, Plant Breeding, Iowa State University, Ames, IA

Research Interests:

  • Theoretically, the impact of genetic bottlenecks is through selection, drift and disequilibrium which limit genetic potential of a crop to sub-optimal levels (Robertson, 1960; Hill and Robertson, 1968; Bulmer, 1971). Despite theoretical considerations of limits to genetic potential, we do not know: 1) whether desirable allelic variants have been eliminated during the adaptation and breeding processes, 2) how to distinguish desirable and undesirable allelic variants in unadapted germplasm, and 3) if desirable alleles can be identified, how do we recover them without sacrificing genetic gains made by previous generations of breeders? 
    Until the emergence of genomics and high throughput genotyping technologies, these types of questions could not be addressed on an experimental basis. Thus, theories developed over 50 years ago have not been tested and modified. We use the tools of genomics, bioinformatics, population genetics, quantitative genetics and modeling to address these questions.  Explicitly, we are developing: 1) experimental strategies for identifying desirable alleles in unadapted germplasm 2) methods to predict the value of desirable alleles, 3) optimal breeding strategies for migrating desirable alleles from unadapted germplasm into elite breeding populations without sacrificing established genetic gains and 4)computational tools to recognize genomic signatures of breeding populations with sub-optimal limits to selection. The impact of addressing these challenges experimentally and analytically will assure that the full genetic potential of maize can be realized using the most effective genetic resources and efficient breeding methods.  From an academic perspective this project also will begin the process of integrating discoveries from genomics with theoretical models of population and quantitative genetics.

Research Interests: Functional genomic and proteomic approaches to disease resistance and susceptibility

  • Functional and Structural Genomics: Functional genomic and proteomic approaches to disease resistance and susceptibility
  • Genome Evolution: Evolution of disease resistance genes

Description: My current research program has been on understanding the molecular basis of host-pathogen interaction. The soybean-Phytophthora sojae interaction has been the main model system investigated extensively in our lab to understand the molecular basis of plant disease resistance. We are also investigating the soybean-Fusarium virguliformae interaction to understand the mechanism used by a phytotoxin to cause plant disease. In addressing the above biological questions we are applying both functional genomics and proteomics approaches that require bioinformatics tools.

Steven Cannon

BCB Faculty Member in the Agronomy Department

Education: Ph.D., University of Minnesota, 2003

Research Interests: Plant genome and gene family evolution, comparative genomics, bioinformatic methods for gene and genome sequence analysis.

BCB Research Areas:

  • Bioinformatics-- methods for gene and genome sequence analysis, including genome comparisons, phylogenetics, and high-throughput transcript profiling.
  • Genome evolution-- patterns and rates of genome rearrangement; effects of polyploidy and transposon activity.

Description: I am a USDA-ARS Research Geneticist, and an adjunct assistant professor in the Agronomy Department.
My ARS research group focuses on bioinformatics for crop improvement, particularly in soybean and other crop legumes. We do this by developing software for analyzing and transferring information between crop and model species - including sequence, genetic, functional, and phenotype data. We study the evolution of disease resistance and nitrogen fixation, and the responses of genomes to polyploidy. We also provide support for two genome sequencing efforts: soybean, and a relative of alfalfa called Medicago truncatula. This support includes development of genetic markers, development of web-based tools for genomic data access and visualization.

Description: Research focuses on development of an HIV-1 vaccine. We are interested in designing antigens that can elicit protective humoral immune responses against the virus. AIDs vaccine development does require significant involvement with bioinformatics because of the significant genetic/antigenic diversity of the virus. My research also heavily involves computational biology as a part of my work deals with prediction of antigen structures and antigen design.

*Hui-Hsien Chou

BCB Faculty Member in the GDCB and Computer Science Departments

Education: Ph.D., University of Maryland at College Park, 1996

Research Interests: Bioinformatics, computational biology and computer-aided biological research

Description: My research interest has been the development of sophisticated computer algorithms to efficiently solve large scale biological research problems. For example, I have developed the automatic DNA sequence clean up programs (LUCY1 & 2) for genomic research, the efficient whole-genome oligo microarray design tool (PICKY) for post-genomic research, and the automatic Perl programming tool (VECT) for biologists. My software tools usually employ novel approaches to computing and provide better results than previous solutions. For example, while most microarray design tools are still based on sequence-level comparison (e.g., BLAST) to screen out nontargets, my PICKY program has embedded a complete suite of thermodynamic equations in its calculations to infer the best oligo candidates based on physics, and it does so orders of magnitude faster than any other comparable microarray design tools with comparable computation depth. My recent research focus is on the computer-aided biological research area. This area differs from computational biology in that the end goals are still the successes in molecular biology, but the approach are greatly improved (both in efficiency and chance of success) by using computer analyses. A good example of this new type of research is the whole-genome siRNA design approach we have conducted using Picky and we have validated (in actual bench experiments) that our computer-aided siRNA design indeed greatly reduces the off-target effects of the experiments.

 
Ongoing projects: National Science Foundation (NSF) has awarded a grant for the research project entitled "Optimal siRNA Design Based on Whole Genome Thermodynamic Analysis" to start in September 2009. RNA interference (RNAi) is a natural phenomenon in cells where siRNAs guide the recognition, inhibition and potential degradation of target messenger RNAs (mRNAs), resulting in the loss of their gene functions. RNAi is an important molecular biology technology that can be used to perform functional genomic studies. It is also suggested that siRNAs can be used as drugs to stop oncogenes in cancer cells or to fight off viruses. The two main goals of this project are to create novel siRNA design software that can select high quality, gene-specific siRNAs based on the comprehensive thermodynamic analysis of an entire genome and to validate the quality of the designed siRNAs with RNAi experiments.

  • Genome Evolution-- I employ mathematical models and computational tools to capture the essential aspects of biological systems. I am interested in the role of pathogen diversity in diseases caused by rapidly evolving organisms (HIV-1, EIAV, HCV), statistical techniques for the detection of recombination or gene conversion, and stochastic models for explaining the uncertainty in biological outcomes
  • Mathematical Biology, Computational Modeling, and Metabolic and Developmental Networking-- Same as above

Description: I am interested in the genomic changes occurring in fast-evolving viruses and how these changes can be used to better understand how they cause disease. I have developed methods to detect recombination and selection in the hundreds and thousands of genomic sequences available for viruses like HIV, HBV, and EIAV. I am currently developing new methods to detect and quantitate selection in overlapping reading frames, a genomic structure common in viruses and heretofor largely unstudied. I am also developing computational models of virus/host interactions and the accompanying statistical methods for data analysis and tting. In the future, I will continue to develop new methods for genetic analysis, for example a model to estimate transposon birth and death rates, and explore extended models of host/pathogen interactions, for example to test the hypothesis that changes in EIAV during disease are helping the virus evade a maturing immune response.

Description:

My laboratory is focused on cell fate determination in the developing retina. Within this context we have generated protein expression datasets, and utilized previously reported gene expression data to identify genes and gene networks involved in this process. My intent is to develop the developing retina as a model for Systems Biology research. Bioinformatics and collaboration in Computational Biology are integral to my agenda.

*Eric Henderson

Education: Ph.D., UCLA, 1984

Research Interests: We are interested in the interface between biology and nanotechnology. This has recently been labeled either bionanotechnology or synthetic biology. The label is of no importance. What is important is that 3.6 billion years of biological evolution has resulted in fantastic developments that are the stuff of which the dreams of nanotechnology is made. The challenge is to understand and, in a practical fashion, transfer these insights to the emerging field of nanotechnology so that the wheel (and eyeball, nose, etc. ) need not be invented twice. This is no small challenge. We have created a few tools that will facilitate this effort and a portion of my time is spent determining how best to provide these tools to researchers. A conclusion I have drawn is that a commercial enterprise accomplishes this and also provides an avenue (in theory) by which future developments may be funded and manifest. This theory is far from proven, however.

Research Interests: Modeling phenotypic selection, demography, phylogenetics

  • Genome Evolution--Theoretical and empirical investigations of natural selection and phenotypic evolution; phylogenetic reconstruction and molecular evolution; modelling population demography and cycling environmental parameters

Description: Research interests in the Janzen Lab involve the study of ecology and evolution, including mechanistic work at the molecular and organismal levels, field studies that document the importance of phenotypic variation, and a comparative view of the long-term consequences of this variation. To do so, we often integrate molecular and quantitative genetic techniques with experimental laboratory and field studies, largely focusing on the impact of environmental and genetic factors in mediating the expression of physiological, behavioral, and life-history traits. Using these conceptual approaches in concert with comparative and computational approaches enables us to assess important biological issues, including

  1. the biological significance of diverse sex-determining mechanisms,
  2. the impacts of environmental and genetic factors on variation in early life-history traits, and
  3. the current and historical genetic and demographic structure of populations, with an emphasis on elucidating adaptive processes and solving conservation concerns.

Description: My research area is metabolic engineering, with a focus on understanding inhibition of biocatalyst growth and metabolism, such as that mediated by the desired product, substrate or a growth media contaminant. The goal of understanding the mechanism of the inhibition is subsequent rational engineering of the biocatalyst for increased tolerance. The tools used in my lab include transcriptome analysis, phenotype analysis and directed evolution and reverse engineering of tolerant strains. Bioinformatics and computational biology are especially relevant to the analysis of transcriptome data and in the interpretation of genome sequence data for evolved mutants.

BCB Faculty Member

Education: Ph.D., University of Buenos Aires, 1997

Research Interests: My laboratory is engaged in understanding the interaction between plants and pests. We use different approaches to study this problem, including metabolomics and transcriptomics analyses. We then use bioinformatics tools to analyze the large amount of data generated. While not fully there yet, we are working towards a “systems biology” interpretation and model generation of these interactions. Another area of research in my laboratory is the analysis of protein structure/function and the acquisition of novel functions by duplicated genes during evolution. Bioinformatics tools are also used in this project, from phylogenetic analysis to protein threading and structure prediction.

Allen Miller

BCB Faculty Member

Education: Ph.D., Wisconsin, Madison, 1984

Research Interests: We study molecular biology of plant RNA viruses with three different but overlapping perspectives

  • Functional and Structural Genomics-- Prediction of RNA secondary and tertiary structure; plant virus genome sequencing and database, novel translation mechanisms
  • Macromolecular Structure and Function-- Same as above

Description:

RNA virus replication:  from plants to humans

We employ plant viruses as easy-to-use model systems to provide basic understanding of how viruses replicate and express genes.  Because of similarities in replication mechanisms across kingdoms, this knowledge may be relevant to major human viruses. Viruses are fascinating as the smallest, minimal replicating entities.  They allow detailed understanding of what it takes to replicate, the essential property that defines life.

How cells decode the genetic code

We investigate the plethora of tricks by which viral messenger RNA usurps and controls the host translational machinery (translation factors and ribosomes).  This gives us a better understanding of fundamental mechanisms of protein synthesis.  This knowledge may allow us to modify viral sequences and mechanisms to control expression of host and viral genes in beneficial ways.

Sustainable control of crop diseases and pests

We strive to improve the knowledge base needed to control the economically important yellow dwarf viruses and the aphids that transmit them.  They vary remarkably in sequence.  We are determining complete nucleotide sequences of dozens of virus isolates from around the world.  We are also attempting to exploit aphid viruses, and aphid-transmitted plant viruses, to control aphids in cereal crops and soybeans.

Research Interests: Microbial pathogenomics, gene regulation

  • Functional and Structural Genomics-- Analysis of genome sequence data; motif signatures; protein structure prediction; gene regulatory regions

Description: Dr. Minion's research interests focus on the molecular basis of pathogenesis and persistence of bacterial pathogens in domestic animals. Major emphasis is on pathogenomics, identification of virulence factors, gene profiling, and development of molecular vaccines in mycoplasmas. His laboratory also studies the molecular basis of persistence of Escherichia coli O157:H7 in ruminants and Salmonella enteritidis in poultry using genetic tools such as signature tagged mutagenesis. Microarray studies are being conducted in Mycoplasma hyopneumoniae, E. coli O157:H7 and L. monocytogenes to understand bacterial in vivo gene expression and its relationship to virulence. Comparative genomics and genome sequencing is being performed to identify virulence factors in mycoplasmas.

BCB Faculty Member

Education: Ph.D., Russian Academy of Sciences, 1993

Research Interests:

  • Singh group works on the interface of fundamental and translational biology. General interest of his group has been to understand the mechanism of alternative splicing, a vital process that increases the coding potential of genome in all higher eukaryotes. Alternative splicing is also associated with a growing number of diseases including neurological and neuromuscular disorders, cardiovascular disorders and cancer. Particular focus of his group has been to understand the molecular basis of Spinal Muscular Atrophy (SMA), a debilitating genetic disease of infants and children. His award-winning discovery relates to finding a unique regulatory element located within the non-coding region (or intron) of Survival Motor Neuron (SMN) gene. He has termed this novel regulatory element as "Intronic Splicing Silencer N1", which is abbreviated as "ISS-N1". Currently, his group is working on the mechanistic details of how ISS-N1 could be used as a therapeutic target. His other interests include RNA-protein interactions and isolation of RNA aptamers as detection and diagnostic tools.

  • Mathematical Biology, Computational Modeling, and Metabolic and Developmental Networking-- Combinatorics and information theory; modelling of complex systems; mathematical biology

Description: As a model for the use of top-down, information-theoretic techniques for handling data describing the evolution of complex systems, the intensive demographic state of a human population has been reduced from the full Leslie matrix description to a single five-dimensional parameter vector. The next stage in the development of this technique involves an analysis of the long-term kinematics of the parameter vector for a given population. It is proposed to use the data for Sweden, which are of high quality and trace back several hundred years. Understanding the kinematics is a preliminary to the development of a dynamics, which should then provide more reliable long-term demographic projections than those obtained from the ergodic theory of Leslie matrices.

Research Interests: Theory of protein crystallization, protein-protein/RNA interactions

  • Bioinformatics-- Three-dimensional atomic structures of proteins form the foundation of our molecular understanding of biology. X-ray crystallography is the major and sometimes only tool for the determination of these detailed protein structures. The bottleneck of this method is to grow a large and good quality crystal used in diffraction. For membrane proteins which carry out some of the most fundamental processes in biology such as photosynthesis, vision and nerve communications, it is exceedingly difficult to find the optimal crystallization conditions because of their peculiar molecular properties. This difficulty is in no small part due to the lack of a transparent and reliable theoretical model to describe the crystallization process. Our research goal is to develop such a theoretical model and to explore the physical principles of finding optimal crystallization conditions. By studying the relationship between the crystallization conditions and the physical parameters of the protein solution, we should be able to provide useful guidance to the search for protein crystallization conditions.

*Amy Toth

BCB Faculty Member in the EEOB Department

Education: PhD, University of Illinois, 2006

Research Interests: The mechanisms and evolution of animal social behavior.

Description: Dr. Toth's work focuses on eusocial colonies of bees and wasps, whose highly integrated societies exhibit a bewildering complexity of individual and colony-level behaviors. She uses an integrative research approach involving field studies of naturally occurring colonies, experimental manipulations in semi-natural or lab settings, and numerous lab techniques to measure physiological, chemical, and genetic characters of individual insects. She has applied next generation sequencing methods to develop sequence databases for social wasp species, in order to enable comparative transcriptomic studies across insect species. The overarching goals of her research are to 1) gain insight into how complex social behavior can evolve from simpler forms of solitary behavior, 2) understand the roles of conservation and convergence in the molecular basis of complex phenotypes, and 3) use new genomic tools to empirically test long-standing ideas about the evolution of sociality.

Examples of ongoing projects include: comparative transcriptomic analysis of honey bee and Polistes paper wasp behavior and caste differences, chemical and transcriptomic characterization of dominance hierarchies in Polistes paper wasps, and exploring the role of DNA methylation in caste differences across multiple social insect species at different levels of sociality.

Research Interests: Retinal cell biology, neuronal and retinal cell fate determination, retinal systems biology, single cell gene expression analysis, transcriptional networks, bioinformatics.

The primary goal of my research is to understand the gene expression programs that drive the development and diversification of retinal ganglion cells, the major output neurons of the retina. These cells vary extensively in their morphologies and are lost in glaucoma, a leading cause of blindness. To achieve this goal, my lab will first develop a molecular taxonomy of retinal ganglion cells in the mouse by profiling individual, labeled ganglion cells. In addition, we will identify the gene networks present in the progenitor cells that produce the retinal ganglion cells. Once these gene networks have been assembled, gain and loss of function studies will be performed to assess the effects of perturbing these networks on ganglion cell production and survival. These experiments will provide insights into how to generate ganglion cells de novo or perhaps how to maintain the survival of these cells in a disease state.

  • Genome Evolution­-Evolution of gene networks underlying sexual development. Molecular evolution. Chromosome evolution. Description:

Description:

Evolutionary and ecological functional genomics associated with the development of the sexual phenotype. Temperature-dependent sex determination (TSD) represents a form of phenotypic plasticity (a thermal sexual polyphenism) where identical genomes can permanently differentiate into either sex depending on the environmental conditions. I am interested in identifying how many distinct systems of sexual polyphenisms exist in nature, how do they work, and why did they come into being. My research addresses the question of whether multiple molecular pathways have evolved to produce ecologically equivalent TSD systems among taxa. I use a comparative evolutionary-genomic framework to examine the molecular basis of TSD in multiple species to identify the regulatory gene(s) that render TSD systems thermo-sensitive. Current projects in my lab encompass candidate gene-discovery and gene expression profiling of TSD and GSD taxa, in an attempt to understand the molecular network associated with sex differentiation in TSD and its regulation. I am particularly interested in understanding how TSD works in nature, and the relative role of adaptive versus neutral processes during its evolution. I am approaching these issues through studies of the functional genomics in an ecologically relevant context, assessing individual variation of gene expression within and among populations. Another research avenue in my lab is focused on comparing turtles possessing XX/XY, ZZ/ZW or TSD mechanisms to study the evolution of sex chromosomes and the genes they contain. This research will test that (1) all sex chromosomes in turtles derive from a common ancestral pair of non-sex chromosomes (or "autosomes"), and that (2) the molecular evolution of genes contained in turtle sex chromosomes differs from that of the same genes found in turtles with TSD since they lack sex chromosomes. Additionally, since I am interested in theoretical and empirical aspects of the evolution and ecology of sex determining mechanisms and related topics (e.g. the evolution of sex ratio, sex chromosomes, and sex-linked traits), modeling can be an effective tool to investigate sex ratio evolution in organisms with alternative sex determining mechanisms by contrasting the influence of thermal sensitivity in population dynamics for TSD taxa as compared to GSD taxa.

BCB Faculty Member

Education: Ph.D., UC, Berkeley, 1996

Research Description:

My research program is broadly focused on evolutionary developmental biology in plants and genome dynamics in maize. In the evolutionary work we employ a variety of computational approaches to questions in molecular evolution from routine phylogenetic reconstructions to quantifying histories of recombination, and using standard and maximum likelihood approaches to test for evidence for selection in nucleic acid sequence. As this work becomes increasingly genome-driven, the informatics techniques are becoming more computational (and in many cases, more rigorous). My research group is also developing a genome-wide collection of transposable element insertions in maize, to serve as distributed platforms for regional mutagenesis. Through this work we are probing mechanisms of endogenous transposable element insertion via statistical and computational analyses of large collections of transposon insertion sites. Our recently published analyses show a clear bias for the Ds transposon to insert into promoter and exon regions, and for DNA insertion sites with particular structural signatures.

Research Interests:

  • My research program involves the functional genomic analysis of plant microbe interactions, and we have three major projects that would be suitable for a bioinformatics student. First, we have employed DNA microarrays to analyze the responses of plants to microbes and are now using these data to test the functions of genes that we hypothesize may be involved in disease defense networks. Second, we are developing high throughput methods to analyze gene functions in soybean using a technique called virus induced gene silencing. Third, we are preparing to do sequencing of the Asian soybean rust haustoria transcriptome using the 454 technology from Roche. I believe that the data sets that are available and the three complementary projects that are in progress in our lab present some excellent opportunities for research projects for a student in the BCB program. I am able to provide financial support for a graduate research assistantship through existing grant funds.

Description:

Dissection of coexpression networks in barley-powdery mildew interactions: a multi-dimensional approach to understanding parasitism by obligate biotrophs

Regulation of gene expression in barley-powdery mildew interactions influences the establishment of fungal biotrophy and the development of host resistance. To identify global expression responses to the powdery mildew fungus, Blumeria graminis f. sp. hordei, 468 Barley1 GeneChips were used to profile the expression of 21,439 genes in inoculated vs. non-inoculated seedlings at hours 0, 8, 16, 20, 24, and 32 for each of nine variants of genes in the Mla resistance signaling pathway, as well as mutants programmed cell death ( NSF Plant Genome Award #0500461 ). We are analyzing these data to build coexpression networks containing genes involved in sugar transport, photosynthesis, WRKY signaling, secretion of PR proteins, signal peptide processing, and abiotic stress signaling. Single cell dsRNAi (TIGS), Virus Induced Gene Silencing (VIGS), transcript based cloning, and proteomics experiments are being used to dissect the various sub-networks and time-course interactions of disease defense pathways.

Description: Plants can be considered "environmentally clean", solar-powered factories that produce a wide range of chemicals from simple precursors (carbon dioxide, nitrogen, sulfur, etc.). These complex plant-derived chemicals include carbohydrates, proteins, oils, and vitamins, and have nutritional, industrial, and medicinal uses. The metabolic processes that biosynthesize these complex molecules are responsive to growth and developmental signals determined by the genetic blueprint of the organism as it adapts to the ever-changing environmental stimuli. These metabolic processes are the chemical basis for life. My research, juxtaposed at the interface between biology and computational sciences, centers on this interplay between the metabolic and regulatory signals: the metabolic network of plants. My foci are 1) the development of software to explore the metabolic and regulatory network in conjunction with experimental data from millions of datapoints (http://metnet.vrac.iastate.edu/), and 2) the elucidation of the metabolic networks associated with the two-carbon activated molecule, acetyl-CoA.
