Tigran Tonoyan

I am a visiting researcher at the CS department of the Technion, hosted by Keren Censor-Hillel.

Before this, I was a postdoc at ICE-TCS, Reykjavik University, under the supervision of Magnús M. Halldórsson.

I received my PhD from TCS-Sensor Lab, University of Geneva, under the supervision of José D. P. Rolim.

Before that, I worked as a software engineer at Synopsys Armenia.
