Aleksander Mądry is a computer scientist and professor at the Massachusetts Institute of Technology. As of 2024 he is on leave at OpenAI leading preparedness team.

Biography

Aleksander Mądry was born in Wrocław, Poland and obtained a bachelor's degree in theoretical physics from the University of Wrocław. He continued his studies at the Massachusetts Institute of Technology with an M.S. in computer science ("Faster Generation of Random Spanning Trees") and a Ph.D. in 2011 [2] under the supervision of Michel Xavier Goemans and Jonathan A. Kelner ("From Graphs to Matrices, and Back: New Techniques for Graph Algorithms"). He spent a year as a postdoc at Microsoft Research New England, then he worked at the École Polytechnique Fédérale de Lausanne (EPFL) until 2015, when he joined the department of electrical engineering and computer science at MIT.

In 2023 he took leave at MIT to join OpenAI to head their "Preparedness" team to evaluate the potential of machine learning models to cause "catastrophic" damage.[1][2] On March 8th Mądry testified to congress on the opportunities and risks of AI[3]. After the Novemer 17 removal of Sam Altman from OpenAI, Mądry resigned, before returning after Altman's reinstatement. [4]

Research

Aleksander Mądry's early work made substantial contributions to the theory of algorithms[5]. In 2011 he developed an approximation algorithm for the maximum flow problem, the first improvement in many years. And then, in 2013, he gave an exact calculation algorithm for the maximum flow problem which was the first to improve on the prior bound of Evan and Tarjan in 1975[6]. Mądry also contributed advances in the k-server problem and the traveling salesman problem [7]. The Pressburger Award wrote: "Aleksander’s results have been celebrated in the community not only because he broke long standing complexity barriers but moreover because he introduced new and very different techniques to the field which since have successfully been picked up by others."

Mądry's most recent work focuses on machine learning and artificial intelligence. In 2018 he developed the method of "adversarial training", a scheme to improve the robustness of machine learning models[8]. Refinements of adversarial training remain the best methods for improving adversarial robustness. Since 2018 Mądry has extended his work to cover other areas of explaining why machine learning works, and investigating the role of data in the accuracy of machine learning models.
