Sepideh Mahabadi
I am a Research Assistant Professor at Toyota Technological Institute at Chicago (TTIC).
I received my PhD in Computer Science, at the Theory of Computation (TOC) group at CSAIL, MIT. I was very fortunate to have Piotr Indyk as my advisor.
For a year, I was a Postdoctoral Research Scientist at Simons Collaboration on Algorithms and Geometry based at Columbia University, hosted by Alexandr Andoni.
Prior to MIT, I received my B.Sc. in Computer Engineering from Sharif University of Technology, Iran 2007-2011.
CV (May 2018): Publications:
My research is mostly focused on Sub-linear Algorithms for Massive Data including (but not limited to) high dimensional computational geometry, streaming algorithms, sub-linear time algorithms, sketching, and graph algorithms.
Service Work:
We are organizing Recent Trends in TCS workshop on January 31st, 2020 at TTIC.

I was on the program committee of ITCS 2019 , and served as a reviewer for ICML 2018 and NIPS 2017.
