Professor Guha Dharmarajan is a veterinarian and disease ecologist. He received his Bachelor of Veterinary Science and Master of Veterinary Science degrees from the Madras Veterinary College, and his PhD from the Purdue University. He started his postdoctoral research at Purdue, and subsequently moved to the Laboratory of Malaria and Vector Research at the US National Institutes of Health (NIH). Following this, he worked as a Ramanujan Fellow at the Indian Institute of Science Education and Research Kolkata. Before joining Krea, Guha was an Assistant Research Scientist at the Savannah River Ecology Lab, The University of Georgia.

Professor Dharmarajan’s research is primarily in the fields of disease ecology and ecosystem health. Specifically, he studies how human-mediated environmental perturbations – global climate change, habitat modification and environmental pollution – affect disease dynamics in human and wildlife populations, and in turn how such altered disease dynamics feedback on ecosystem health by impacting eco-evolutionary processes at the individual, population and community scales. He has taught students across four institutions in India and the US. At Krea, he teaches Scientific Reasoning, Biostatistics, Ecology and Conservation Biology, and Global Change Biology.
