I am a researcher at the Algorithms and Complexity group of CWI (Dutch Centre for Mathematics and Computer Science) and part-time full professor at the ILLC of the University of Amsterdam. I’m also a member of QuSoft. A long time ago I was a PhD student at CWI and ILLC, and then a postdoc at UC Berkeley.
My research is on various topics in computational complexity theory, quantum information theory and discrete mathematics. A unifying theme in my work is the interaction between amortization, symmetry and approximation.
