Dimitris Tsipras

I am a PhD student in Computer Science in the EECS department of MIT where I am advised by Aleksander Mądry. My goal is to develop efficient tools for building robust and reliable machine learning systems that can have impact on the real world. I occasionally contribute to MadryLab's blog.

I did my undergraduate studies in the ECE department of NTUA, Greece, where I was a member of CoReLab working on Algorithmic Game Theory with Dimitris Fotakis.

I spent the summer of 2018 at Google Brain, working with Yoram Singer on optimization aspects of neural networks.
