Career Summary
Sabit has shown himself to be a truly exceptional young conservationist in Bangladesh. He has more than 7 years of experience in several primate research. Notably, he is also committed to nocturnal fieldwork, be it of bats, reptiles, amphibians, and slow lorises. This level of versatility is truly rare and will allow him to produce work of the highest caliber, bringing Bangladesh’s biodiversity to an international audience. Bangladesh is a country of extreme importance to primate conservation, largely on the map due to its unique gibbons. The Bengal slow loris remains virtually unstudied in Bangladesh except for the unique work done by Sabit and his team. He published more than 25 research articles in national and international journals. He presented his research at two international conferences. He is awarded by NST fellowship, The Explorers Club, IdeaWild, and SUFAL innovation grant of the Bangladesh Forest Department. He is a member of the IUCN SSC Section on Small Apes, Save the Frogs and Bangladesh Bird Club.
