I am primarily interested in landscape & urban ecology, conservation biology, and understanding species' response to rapid environmental changes. For my Ph.D., I am working on understanding squirrel distribution and response to anthropogenic change using modeling approaches in India. I am using multiple sources of occurrence data for 30 species of squirrels in India and use the same to create species distribution models and understand past, present, and future distributions of these species and understand how anthropogenic landscape modifications and climate change is likely to affect them. I am also looking at species occupancy and response to urbanisation using the Three-striped palm squirrel as a model system in Tirupati.
My previous work in the lab includes working on marmots in the Trans- Himalayas, where I was looking at genetic connectivity across their range in India using fecal samples.
Before joining the lab in 2017, I worked on multiple projects in various capacities. During my Master's summer internship, I carried out a study on understanding the demographic structure of non-human primates in the Central Western ghats of Karnataka. For my Master's dissertation, I worked on understanding the genetic structure and population connectivity of Asian elephants in Karnataka and Tamil Nadu.
