Sriram Sankaranarayanan

Biography

Sriram Sankaranarayanan is a faculty member at IIM Ahmedabad in the area of Operations and Decision Sciences.

Sriram's research interest lies in solving game-theoretic and optimisation problems that include integer variables. In particular, he has worked on mixed-integer linear programming, complementarity problems and mixed-integer bilevel programming. Apart from proving structural results and developing algorithms to solve these problems, he is also interested in using these methods for real-life problems which are of social interest.

He has worked on using tools from optimisation to analyse energy-market policies, with a particular interest to combat climate change.
