Brief writeup on area of specialization/awards/achievements:
 

The area of specialization is Evolutionary Genetics with particular reference to the work done on population and behaviour genetics of Indian species of Drosophila. The important findings pertain to the role of natural selection and random genetic drift, dynamics of inversion polymorphism, heterosis, balanced polymorphism, genetic coadaptation, linkage disequilibrium, population substructuring, sexual isolation, sexual selection, genetic basis of hybrid male sterility, fluctuating asymmetry, trade-offs, genetic variance and thermal adaptation, chill coma recovery and latitudinal variations, size-dependent sexual selection, rare- male mating advantage, female remating and sperm displacement which are of considerable evolutionary significance.
