Sepideh Mahabadi (سپیده مه آبادی)
I am a Postdoctoral Research Scientist at Simons Collaboration on Algorithms and Geometry based at Data Science Institute of Columbia University , working with Prof. Alexander Andoni. Next year, I will join TTIC as a Research Assistant Professor. My research is mostly focused on Sub-linear Algorithms for Massive Data .
I received my PhD in Computer Science, where I was a student at the Theory of Computation (TOC) group at CSAIL, MIT. I was very fortunate to have Prof. Piotr Indyk as my advisor.
Prior to MIT, I received my B.Sc. in Computer Engineering from Sharif University of Technology, Iran 2007-2011.
