Dimitrios Myrisiotis

I am a research fellow in Computer Science at the School of Computing of the National University of Singapore, hosted by Arnab Bhattacharyya. My research interests are computational complexity theory, computational learning theory, and causality.

Clocks no tic tac

Previously, I earned a PhD in Computing from the Department of Computing of Imperial College London, whereby I was advised by Mahdi Cheraghchi. I hold a MSc in Logic, Algorithms and Computation from the Department of Mathematics of the University of Athens, and a joint BEng-MEng diploma from the School of Mechanical Engineering of the National Technical University of Athens. During my studies at the Department of Mathematics, I worked with Stathis Zachos and Iordanis Kerenidis on quantum computational complexity theory, and during my studies at the School of Mechanical Engineering, I worked with Evangelos Papadopoulos on four-legged robots.
