I am a herpetologist with research interests broadly centered around behavioural and evolutionary ecology of reptiles. My integrative approach combines field surveys and computer-based modelling to provide insights into the adaptive significance of reptiles to the changes in their environment.


A global assessment conducted by myself and colleagues shows that one in five species of reptiles in the world do not have enough information to make a conservation status assessment (classed as “Data Deficient”) and a further one in five being globally threatened with extinction, mainly due to habitat and environmental change. Most of my previous and current research focuses on understanding these patterns and the underlying processes.
