Research interests

The conservation of species, landscapes and biodiversity is the central theme that drives my research interests. However, given the increasing lack of natural areas free from human-impact, I focus not just on conservation in natural systems, but also in human-modified and human-dominated landscapes. Much of my work involves the study of mammalian carnivores, and in particular, meso-carnivores. In general, carnivores exist at relatively low numbers and yet can dramatically influence animal and plant communities. Thus, by studying carnivores, we can gain insight into the importance of the individual within natural systems. However, I am by no means restricted to carnivores or even mammals in my research program.

The following are some of my major research themes:

-The role of carnivores in structuring species assemblages

-Human-subsidised carnivores and their interactions with wildlife at multiple levels viz. as predators, competitors and vectors of pathogens

-Disease ecology of carnivores

-Conservation of dry grassland and semi-arid ecosystems in India and their associated faunal elements, in particular the Indian bustard, Indian fox and Indian wolf

-Human-wildlife conflict outside protected areas

-Movement ecology and resource selection of animals
