Description of Research

The laboratory focuses on application of computational biology to develop tools for translational bioinformatics. The specific areas of interests of the laboratory include:

  • development and application of artificial intelligence based methods to address complex biological data classification problems;
  • computer aided drug designing; including molecular modeling, molecular dynamics, homology modeling, virtual screening and cheminformatics for lead identification;
  • application of comparative genomics methods to identify novel drug targets and gene expression regulatory elements like miRNAs and transcription factors;
  • applications for Systems Biology for translational bioinformatics;
  • computational and statistical analysis of NGS (Next Generation Sequence) data and;
  • development of biological databases and algorithms.

The Group exploits Artificial Intelligence (AI) for solving various bioinformatics and cheminformatics research problems. The group has developed several web servers for sequence based prediction protein families, members of which do not have obvious sequence similarities, conserved motifs and domains. Recently we have developed servers for:- Plant viral suppressors (server: VSupPred), Cyclins (server: CyclinPred), Lipocalins (LipocalinPred), CDK inhibitor proteins (CDKIPred), virulent proteins (VirulentPred) and Fungal Adhesions (FaaPred). The group has recently developed standalone tools for new generation high throughput data analysis, for example miRMOD is a tool for determination of modified miRNAs by analysis of sRNA NGS data and its effect on targets. A Random forest algorithm for prediction of cancer stage in the most common renal cancer (ccRCC), based on patient RNAseq data, has been developed in the laboratory. The group is developing a proteomics tool for analysis of volatome of TB patients in collaboration with Translational Health Group at ICGEB. The group is collaborating with “Omics of Algae” group at ICGEB to perform NGS and metabolomics of algal genomes of importance for Biofuel production. The databases and tools developed by the group are freely available as webservers at http://bioinfo.icgeb.res.in.
