I am a Senior Postdoctoral Researcher ("Collaborateur Scientifique") of FNRS, working within the Algorithms Research Group at the Université Libre de Bruxelles (ULB). From October 2018 until September 2020, I was a postdoctoral researcher at the same group, hosted by John Iacono.
ResearchI am broadly interested in Algorithms, Optimization and Machine Learning. The main focus of my research is on Algorithms and Optimization under uncertainty (Online Algorithms, Dynamic Algorithms). I also have a strong interest in related areas like Online Learning, Data Structures and Computational Geometry.
