Sahotra Sarkar (born 1962) is a philosopher of science  and conservation biologist at the University of Texas at Austin. He is one of the founders of systematic conservation planning within conservation biology, promoting the use of multi-criteria decision analysis  and supervising the creation of the ConsNet decision support system. In this context he has advocated participatory environmental planning and strongly criticized the imposition of authoritarian and discriminatory environmental policies on local residents. His laboratory also works on a suite of neglected tropical diseases (or diseases of poverty) including Chagas disease, dengue, leishmaniasis, and tick-borne diseases.
In the philosophy of biology Sarkar is known for his work on reductionism and criticism of hereditarian thinking in biology as well as the use of informational concepts in molecular biology. In the philosophy of physics Sarkar is known for controversially defending the conventionalism of simultaneity in special relativity (with John Stachel) and suggesting a stochastic modification of quantum dynamics. Earlier in his career he worked in mathematical population genetics where, in collaboration with Wing Ma and Guido Sandri, he was responsible for the standard recursion relation to compute the Luria-Delbruck distribution in bacterial genetics.
Sarkar is originally from India where he lived in Darjeeling until 1975. He earned a BA from Columbia University, and a MA and PhD from the University of Chicago. He was a Fellow of the Wissenschaftskolleg zu Berlin (1996 -1997), the Dibner Institute for the History of Science (1993 -1994), and the Edelstein Centre for the Philosophy of Science (1992). He was a Visiting Scholar at the Max Planck Institute for the History of Science in Berlin (1997 -1998, 2002 -2003) and taught at McGill University before moving to Texas. His doctoral students include Michael Ciarleglio, David Frank, Trevon Fuller, Justin Garson, Susan Mooney, and Samraat Pawar.
