The core focus of the life sciences research area team is computational genomics. This involves researching and designing solutions that employ a combination of artificial intelligence, cognitive computing capabilities, robotic process automation, the internet of things, and cloud computing to fully digitize the life sciences value chain.
The team works across the following areas of research:
- Human genome variation interpretation: This group works on the development of tools and algorithms in the area of human genome interpretation with DNAseq, RNAseq and epigenetic data analyses. Key collaborative projects include diagnoses of rare disorders of unknown etiology for better understanding of gene pathways and disease pathology, exploration of next-generation sequencing as a replacement for screening tests and genetics in cancer treatment modalities. Another area of research is the construction and use of genotype-phenotype-disease networks using natural language processing to identify novel gene-disease relationships.
The group is led by Dr. Rajgopal Srinivasan and includes Akriti Jain, Poulami Chaudhuri, Sadhna Rana, Sutapa Datta, Uma Sunderam, Aditya Rao, V G Saipradeep, Naveen Sivadasan & Thomas Joseph

Metagenomics and systems biology: This group specializes in identifying microbiome-based biomarkers that have clinical application or utility in the early detection or diagnosis of asymptomatic diseases and metabolic or genetic disorders. Modeling and simulation of biological systems that affect different hierarchies of life is also another area of interest
