A.P.J. Abdul Kalam: A teacher till the very end

My research group is engaged in fundamental research in the following areas:

- Statistical learning theory: We are developing theory and algorithms for predictions problems (e.g., learning to rank and multilabel learning) with complex label spaces and where the available human supervision is often weak.
- Sequential prediction in a game theoretic framework: We are trying to understand the power and limitations of sequential prediction algorithms when no probabilistic assumptions are placed on the data generating mechanism.
- High dimensional and network data analysis: We are developing scalable algorithms with provable performance guarantees for learning from high dimensional and network data.
- Optimization algorithms: We are creating incremental, distributed and parallel algorithms for machine learning problems arising in today's data rich world.
- Reinforcement learning: We are synthesizing and further developing concepts and techniques from artificial intelligence, control theory and operations research for pushing forward the frontier in sequential decision making with a focus on delivering personalized health interventions via mobile devices.

My almae matres are IIT Kanpur (B.Tech., 2002) and UC Berkeley (M.A., 2005 and Ph.D., 2007. Advisor: Peter Bartlett). I was a research assistant professor at TTIC from 2008 to 2010. From 2010 to 2012, I was a post-doctoral fellow at UT Austin where I worked with Inderjit Dhillon and Pradeep Ravikumar.

Activities at U-M I'm involved with:

- Learning Analytics at Michigan
- Michigan Institute for Data Science (MIDAS)
- Pushing Mobile Interventions Forward (a seminar series I coordinate)
- Statistical Machine Learning Reading Group
- Statistical Reinforcement Learning at Michigan
