Maria Apostolaki

I am currently a Postdoctoral Researcher at CMU advised by Prof. Vyas SekarMy research focuses on Internet routing and its implications on security and performance. I am particularly interested in the impact of the network on Blockchain systems. My most recent work is on cryptocurrencies' anonymity. I also enjoy working with programmable data planes.


During my studies, I have been a visiting student at MIT (2019), working on buffer management. I have also worked on analyzing data center traffic as a research intern at Microsoft Research, Redmond (2018), and Google, Mountain View (2017).

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


I will be joining Princeton ECE as an Assistant Professor starting Fall 2022!
