Research Interests

Our major research interest has been in the field of human origin, health and disease. We are interested in understand the complex origin and affinities of Indian populations, using the genomics variations of contemporary populations and ancient biological remains. We are also interested in understanding the impact of endogamy on health and disease of South Asians. Our other research focus is to find the molecular basis of; male infertility, cardiovascular diseases, sex determination, and mitochondrial disorders. Some of our most significant contributions in the above field are as follows:

We discovered that the enigmatic tribal populations of Andaman Islands are the first modern humans who migrated out of Africa through southern coastal route about 65,000 years ago (Science, 2005). Subsequently, we found that the present-day Indian populations descend from two diverse groups; namely, Ancestral South Indians (ASI) and Ancestral North Indians (ANI) (Nature, 2009). Further, we found that the ASI and ANI have admixed during the past 2000 - 4000 years (American Journal of Human Genetics, 2013); followed by strict endogamy leading to population-specific recessive disease, due to founder events (Nature Genetics, 2017).
