With the huge advances in DNA sequencing technology and computational algorithms, it is now possible to identify genomic alterations of a cancer genome in an unprecedented way. Now-a-days, massively parallel DNA sequencers can generate several terabytes of sequence data within a short span of time. We generate multi-omics datasets and apply stringent computational pipelines to analyze these large multi-omics datasets to answer important scientific questions in cancer and population genomics. In particular, our current research in cancer is to understand and study - (i) molecular signatures that captures progression states of oral pre-cancers and frank oral cancers, (ii) specific tumour features that are associated with local lymph-node metastasis and tumor recurrence and (iii) nature of immune contexture in various stages of oral cancer.
Our team provides major analysis support to the bioinformatics and statistical wing of the International Cancer Genome Consortium (ICGC) – India project on oral cancer, SyMeC project on oral cancer and cervical cancer and NIBMG-Flagship project on Cervical cancer. In these projects, we are identifying the nature and extent of genomic alterations in Indian oral cancer and cervical cancer patients. We are generating and analyzing data on whole-exome, whole-genome DNA sequencing, genome-wide CNV array, epigenomic array and RNA-sequencing from multiple gingivo-buccal oral and cervical cancer patients to discover the complete repertoire of genomic alteration of the patients and possible therapeutic options.
In past, I have worked extensively in human evolutionary genetics with special reference to natural selection. I have continued interest in human evolution and human population genetics. Presently, I am working with my colleague Dr Analabha Basu, to understand baseline genome variation in healthy individuals from whole genome sequencing data from multiple Indian ethnic population samples.
COVID-19 has impacted our research and daily life heavily in last two year. My team also contributed to the understanding of the ongoing viral evolution of SARS-CoV-2 lineages. We were trying to understand the host genomic factors that modulates the infection rate and disease severity in affected individuals.
