Portrait of Alex Slivkins

Alex Slivkins

Principal Researcher


I am a Principal Researcher at MSR New York City. Before joining MSR-NYC in 2013, I was a member of MSR Silicon Valley since 2007. I received my Ph.D. in Computer Science from Cornell University, advised by Jon Kleinberg.

Full publication list (with abstracts, by year and by topic).

My book, Introduction to Multi-Armed Bandits, has been published with Foundations and Trends  in Machine Learning in November 2019. It is based on this class at UMD, and partially on that class at Columbia, providing a textbook-like treatment of the subject. A plain-formatted draft can also be found on arxiv.

My research interests are in algorithms and theoretical computer science, spanning machine learning theory, algorithmic economics, and networks. Across various domains, I am drawn to algorithmic problems with informational constraints. I am particularly interested in online machine learning and exploration-exploitation tradeoff, and their manifestations in mechanism design and human computation. Much of my earlier research was on the analysis of Internet and social networks, metric embeddings, and distance/routing data structures. My work has been recognized with the best paper award at ACM EC 2010, best paper nomination at WWW 2015, and the best student paper award at ACM PODC 2005.
