I am a research fellow at the National Centre for Biological Sciences (NCBS), Bangalore, India.

I am primarily an evolutionary ecologist: I try to understand how organisms are adapted to their environment. In addition I am interested in the evolutionary and ecological mechanisms underlying the dynamics of populations. I also work on understanding large-scale variation in both population size and population change.

Other interests include the population ecology and control of problem species (especially non-native invasive species), and the design, implementation, and analysis of large-scale biodiversity monitoring programmes. Large-scale data collection provides the opportunity to collaborate with volunteers in doing Citizen Science. An example of such a collaboration is MigrantWatch.

My Master's thesis (from the Wildlife Institute of India, Dehradun) was on the social organisation of the great tit, Parus major, in the foothills of the western Himalayas. For my PhD, I worked with Jane Brockmann, at the University of Florida on sexual selection in weaverbirds (Ploceus sp). I then did postdoctoral work with Nick Davies at the University of Cambridge, and with  Mark Eaton and Richard Gregory at the RSPB.

I am on the editorial boards of Current Conservation, and Ibis; and am a trustee of the New Ornis Foundation, which publishes Indian Birds.
