Sotiris Apostolakis

I am currently working at Google on performance analysis and compiler optimizations of warehouse-scale systems. I completed my PhD in Computer Science in 2020 as a member of the Liberty Research group at Princeton University, under the supervision of Prof. David I. August.

My dissertation work focused on compilers, program analysis, and automatic parallelization. During my time at Princeton, I have also worked on system security and computer architecture. During my internships at Facebook (summer 2018) and Intel (summer 2017), I worked on binary analysis.

Before joining Princeton, I earned my Diploma in Electrical and Computer Engineering at the National Technical University of Athens, Greece.
