(I receive an unhealthy number of emails per day which makes me feel very overwhelmed. Please consider not sending your email unless it is really necessary. I apologize if I miss your email - I give response priority to my students (undergrad and grad), Princeton staff & faculty, and my collaborators.)
Questions about the ORF 363 waitlist? Please read this before emailing me.
I am a Professor at the Dept. of Operations Research and Financial Engineering of Princeton University. I am also an affiliated faculty member of PACM, Computer Science, Mechanical & Aerospace Engineering, Electrical Engineering, the Center for Statistics and Machine Learning, and a proud Academic-Athletic Fellow of Princeton's Men's Tennis Team and Princeton's Women's Tennis Team. I serve as the Director of the Optimization and Quantitative Decision Science Certificate Program. In 2021-2022, I took a temporary leave from Princeton to join Citadel GQS as a Visiting Senior Optimization Fellow.
In Spring 2021, I served as the Volunteer Assistant Coach of the Princeton Men's Tennis Team, learning a lot from BP, Damian, and our incredible athletes. From Winter 2020 to Fall 2021, I was a Visiting Research Scientist at Google Brain. From Fall 2014 to Summer 2019, I was an Assistant Professor at Princeton. In 2012-2014, I was a Goldstine Fellow at the Dept. of Business Analytics and Mathematical Sciences at IBM Watson Research Center.
I received my Ph.D. in Electrical Engineering and Computer Science from MIT in August 2011. Throughout my graduate studies, I was affiliated with the Laboratory for Information and Decision Systems. My advisor was Prof. Pablo Parrilo.
In 2011-2012, I was a postdoctoral associate at MIT working jointly at the Laboratory for Information and Decision Systems with Prof. Pablo Parrilo and at the Computer Science and Artificial Intelligence Laboratory and the Robot Locomotion Group with Prof. Russ Tedrake.
