Research Experience
Held visiting professorships at various institutions since 2001, most recently at ETH Zurich and Université Sorbonne Paris Nord. Enjoys collaborative research and met many coauthors at research workshops around the world.
Education
Obtained PhD from Université libre de Bruxelles (ULB) in 2001, with a fellowship from FNRS, after spending some time at the University of Washington.
Background
Professor of computer science, with research interests in theoretical computer science and discrete mathematics. Particularly interested in computational geometry, combinatorial algorithms, and geometric combinatorics. Earlier works dealt with data compression and problems in information theory.
Miscellany
Enjoys participating in research workshops and has given several online talks at various institutions globally.
