I have been involved in research and conservation in Arunachal Pradesh since 1995. While a primary focus of my work has been on hornbills, I have carried out exploration surveys and camera-trapping studies for mammals, examined hunting and logging impacts, long-term monitoring of hornbill nesting and tree phenology. Studying frugivory and seed dispersal is my first love. I have also worked with communities for conservation that includes initiatives on education, health, rural energy and livelihoods, some of which I view as failures. I have been a member of the National Tiger Conservation Authority (NTCA) and the State Wildlife Advisory Board of Arunachal and engaged with the government on the management/evaluation of some tiger reserves and several Protected Areas and critiqued proposed hydro-power projects in Arunachal Pradesh. I have written several books for children, a field guide on the Trees of Arunachal Pradesh and published my research work in over 40 peer-reviewed articles. I have a blog in which I write about my field experiences. I have received the National Geographic Emerging Explorer award (2010) and the Whitley Fund for Nature award (2013).
