Interests:

As a young researcher, I am exploring different areas/domains of computational biology to identify my niche. I love the blend of research and software development and I am looking forward towards applications of statistical modeling, machine learning (specially AI and deep learning), parallel computing and optimization algorithms to raise, study and answer the challenging biological questions.

 

Research:

1. Master's Project: (~12 Months)

Name: Graphically Accelerated CUDA based Systematic Conformer Generation Method.

Guide: Dr. Manali Joshi, University of Pune.

Area: Cheminformatics

Nature: Tool

The tool is written in C++ and also ported on JAVA using SWIG bindings provided by OpenBabel. The tool focuses on systematic conformer generation of small molecules. The serial program is written, but now I attempt to port it on GPU (NVIDIA TESLA K20) using OpenACC and also on HADOOP in order to cater computational intensity. Along with this, my program is being redesigned to use multithreading using OpenMP and GNU Parallel. This project helped me to gain strong background of parallel computing and Object oriented programming using different libraries which can be proved useful even for different fields where parallel computing can be adapted. Along with this, I have built a database using my own text mining Perl LWP scripts to test the tool performance.

 

2. Model for Identification of Antimicrobial Peptides.

Guide: Dr. Valadi Jayraman

Area: Data Mining and Analysis.

Nature: Analysis

I have also worked on a machine learning project where I was leading a team of eight members. Like any other machine learning project, it involved text mining (I used Perl LWP) followed by feature extraction where I personally tested and used different APIs (such as Discovery studio API and more) followed by Model building using WEKA, LIBSVM and randomForest (R). I also worked on model refinement by doing grid search.
