Aleksander Mądry I am a faculty in the MIT EECS Department, a member of CSAIL and of the Theory of Computation group. I received my Ph.D. from MIT in 2011. Prior to joining the MIT's faculty, I spent a year as a postdoctoral researcher at Microsoft Research New England and then I was on the faculty of EPFL until early 2015. Research Interests: My research aims to identify and tackle key algorithmic challenges in today's computing. My goal is to develop theoretical ideas and tools that, ultimately, will change the way we approach optimization -- in all shapes and forms, both in theory and in practice. I am also interested in understanding machine learning from a security/robustness perspective and building the science of modern ML. To read about my work in machine learning, see here (or take a look at our blog).
