Summary of Research:

Computational Immunology and Immunoinformatics
Recent COVID-19 pandemic has highlighted the urgency to quickly respond to new infectious agents, and develop therapeutics and preventive strategies in a reasonable time to minimize the loss of life. Vaccines are most effective preventive measures in containing the infectious diseases. Our lab is interested in better understanding the principles and molecular mechanisms governing the antigen specificity to be used in rational design of vaccines. We will use the molecular structure (experimental and models) and sequence data (NGS) in public databases to understand complex interplay of T-cell receptor binding to antigen-MHC complex and effects of genetic variation. We will develop computational tools, algorithms, pipelines, and databases of immunological importance to be used by research community.

Understanding chromatin site targeting by transcription factors
Transcriptionally inactive chromatin is packed in nucleosomes that resists the binding of transcription factors. However, certain transcription factors can still access their target sites to open the chromatin and initiate transcription. Our interest is in understanding how such transcription factors access their binding motifs in the chromatin using structure modelling based approaches in conjunction is NGS based high throughput data. Availability of nucleosome positioning data, x-ray structures of transcription factors and ChIP-seq of transcription factors in public databases give opportunities to understand gene regulation. We will develop computational tools for analysis of gene regulation.
