Marco Tomamichel holds a joint appointment as CQT Principal Investigator and Professor in the Department of Electrical and Computer Engineering, National University of Singapore. His research interests lie in the intersection of information theory, cryptography and quantum mechanics.
Marco received an MSc in Electrical Engineering and Information Technology from ETH Zurich in 2007. He followed his interest in quantum information to graduate with a PhD in Physics at the Institute of Theoretical Physics, also at ETH, in 2012. He came to CQT for a postdoctoral stint, then was a Research Fellow at the University of Sydney and an Associate Professor at the University of Technology Sydney before returning to NUS in 2020.
