I am a graduate in Wildlife and Conservation Management from the University of Queensland, Australia, and I’m currently a PhD Candidate at the same university. A member of the IUCN Species Survival Commission: Cat Specialist Group, Wildlife Conservation Network Scholar, Re:wild Associate Scientist, and a member of the Fishing Cat Conservation Alliance, I have a strong interest in Sri Lankan wildlife and in particular the ecology and conservation of urban mesocarnivores. In 2017, I co-founded the non-profit Small Cat Advocacy & Research and I’m currently conducting research on the world’s only known hyper-urban population of fishing cats, found in Colombo.
A chance encounter with an orphaned fishing cat in 2012, made me pivot from studying the Sri Lankan leopard, and focus solely on this elusive, amphibious feline. I founded the Urban Fishing Cat Conservation Project in 2013, and my research focuses on studying how the species is adapting to the rapid urbanisation, while raising the species profile amongst stakeholders and the public. This project was the first in the world to use GPS collars to track this species and is the first in Sri Lanka to collar and track female fishing cats.
My team and I work closely with the Department of Wildlife Conservation, the Sri Lanka Land Development Corporation, and the Urban Development Authority to uncover the secret life of this endangered species, and understand how we can better protect it, along with its urban habitats.
