Arjun Viswa specializes in herpetology, landscape ecology, evolutionary ecology, and conservation biology. His research combines field-based biodiversity surveys, taxonomic research, trophic ecology, and spatial distribution modeling, integrating laboratory-based molecular work with historical museum specimens to document and understand lesser-known and threatened taxa. He has worked as a research fellow on conservation and biodiversity projects across diverse landscapes of India, from the Ghats to the oceanic islands.
His research also involves human–wildlife interactions and animal behavior, focusing on the social and landscape attributes to help reduce human–wildlife conflict and develop effective conservation strategies. Since 2023, he has focused on documenting and protecting the biodiversity of the Eastern Ghats, particularly threatened and lesser-known taxa, and has contributed to IUCN Red List assessments, especially for species endemic to the region. His long-term goal is to strengthen scientific understanding and conservation of the Eastern Ghats as a globally significant biodiversity hotspot.
