Position: Associate Professor/Research Committee Chair

Appointed Subject: Zoology

Subject Area: Forest Zoology and Mammalogy/ Wildlife and Conservation Biology

  • 2017: PhD Conservation Ecology – Massey University, Auckland, New Zealand.
  • 1990: MSc Zoology (Ecology) – Tribhuvan University, Kathmandu, Nepal.
  • 1987: BSc Zoology — North Eastern Hill University, Shillong, India.

I studied Zoology (Ecology) for my bachelor’s and master’s degrees and conservation ecology for my PhD. I have been involved in field research on large herbivores and carnivores since 2008. My research interests are the diet and the nutritional ecology of captive, domestic, and wild species. The research species and system range from elephants to leopards and tigers in the Nepalese Himalayan foothills. My long-term interests include developing methods to quantify the diet and nutritional composition of wild animals. I am involved in teaching Zoology and mammalogy; conservation and wildlife biology at the Institute of Forestry, Pokhara, Nepal.
