Openings

I have openings for highly motivated Master's and Ph.D. students to work on fascinating research problems in applied game theory and research challenges at the intersection of Machine Learning, Game Theory, and blockchain technology. I am excited about how to design strategy-proof protocols/ algorithms for modern marketplaces; that is, strategic agents do not manipulate them. I am also intrigued by the fact that with appropriate incentive engineering, blockchain technology has not only solved distributed consensus but also enabled the distribution of trust across the whole network. I aim to make AI and distributed systems fairer and strategyproof through different research problems. You must be admitted to IIITH if you are interested in working with me as a regular student. If you're interested, feel free to email me to schedule a meeting. I do not have any internship openings for Bachelor's or Master's students.
