Behavioral Ecologist studying wildlife in human-dominated landscapes

I explore how animals use space, signals, and social strategies—and what that means for conservation

Currently

Mating dynamics in a lekking ungulate

I am a National Postdoctoral Fellow at the Centre for Ecological Sciences (CES), IISc Bengaluru, working with Prof. Kavita Isvaran on the mating dynamics of blackbuck (Antilope cervicapra) in a natural lekking population at Tal Chhapar, Rajasthan. I study how males establish and hold display territories, how signalling links to competition and dominance, and how females choose mates within the lek.

Previously

Territory formation and maintenance in free-ranging dogs

During my PhD (defended September 2025) at the Department of Biological Sciences, IISER Kolkata, I trained as a behavioral ecologist under Prof. Anindita Bhadra. Using free-ranging dogs as a model system, I investigated how territories form, persist, and are maintained in human-dominated landscapes.

My work tested how resource distribution predicts territory size and group density (Resource Dispersion Hypothesis, RDH), and examined behavioral responses to resource pulses and human cues. I also studied resting-site ecology, social associations, and scent-based communication, alongside broader work on the urban scavenger guild to understand ecological roles within city ecosystems

Beyond research

Citizen science & outreach

I contribute actively to iNaturalist and Wikimedia Commons, and I build citizen science and outreach efforts that help people notice—and care about—the wildlife living alongside us.
