Dr. Antonios Varvitsiotis received a PhD in Mathematical Optimization from the Dutch National Research Institute for Mathematics and Computer Science (CWI). Prior to joining SUTD he held Research Fellow positions at the Centre for Quantum Technologies (Computer Science group) and the National University of Singapore (Department of Electrical and Computer Engineering and Department of Industrial and Systems Engineering). He also holds a MSc degree in Theoretical Computer Science and a BSc in Applied and Theoretical Mathematics, both from the National University of Athens in Greece. Dr. Varvitsiotis research is focused on fundamental aspects of continuous and discrete optimisation, motivated by real-life applications in data science, engineering, and quantum information.
