Research Interests

The group works on evolutionary biogeography and systematics with a focus on Asian amphibians and reptiles. Further, studies focussed on specific endangered reptile and amphibian species, on their ecology and conservation are being carried out. Characterization prokaryote diversity in various biota and identifying ecological roles of symbiotic microbes in different organisms is also being carried out.
