Research line: Cryptography in a quantum world
Serge received his M.Sc. in mathematics from the Swiss Federal Institute of Technology (ETH) Zürich, and he obtained his Ph.D. in computer science from the University of Aarhus in Denmark on the topic of information-theoretic cryptography. After his graduation, he spent one year as a Postdoc Research Fellow at the computer science department of Macquarie University in Sydney. In 2004, he joined the Cryptology Group at CWI in Amsterdam, headed by Ronald Cramer, where he now holds a tenured Senior Researcher position. Serge also teaches regularly at the mathematical institute at Leiden University.
Serge’s primary field of interest is the mathematics of cryptology. One strong focus of his research is on understanding the possibilities and limitations of information-protecting techniques in the light of quantum mechanics, and on developing mathematical tools for capturing and studying concepts like ‘information’ and ‘computation’ in a quantum world.
