I do not have any open PhD or postdoc positions at the moment.

Foreign students: I don't supervise summer internships unless they are by graduate students exceptionally well in tune with my research (which is theoretical computer science with focus on quantum algorithms and complexity; it's not physics, not cryptography, not data science, not web-design etc.), so please don't send me your generic internship applications.

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 and part of the Amsterdam TCS ecosystem. A long time ago I was a PhD student at CWI and ILLC, and then a postdoc at UC Berkeley. My main scientific interests are quantum computing and complexity theory, though I have also dabbled in error-correcting codes, data structures, operations research, and theoretical machine learning.

- My CV.
- My publications (see also Google Scholar, arxiv, DBLP, MathSciNet).
- Courses that I have taught or otherwise have been involved in.
- Current PhD students: Yanlin Chen, Lynn Engelberts.
- Former PhD students: Giannicola Scarpa (graduated 2013, now an Associate Professor at Universidad Politécnica de Madrid), Srinivasan Arunachalam (graduated 2018, first a postdoc at MIT, now working at IBM Research), András Gilyén (graduated 2019, then a postdoc at Caltech, now at Rényi Institute of Mathematics, Budapest), Sander Gribling (graduated 2019, now a postdoc at IRIF, Paris, soon to be Assistant Professor at Tilburg University), Jouke Witteveen (graduated 2020), Joran van Apeldoorn (graduated 2020, then a postdoc at University of Amsterdam).
- I am a coordinating editor of Quantum. I have been an editor of SIAM Journal on Computing, Theory of Computing, and Quantum Information and Computation.
- Conferences where I was/am on the program or steering committee:

- Some things that I recently was (co-)organizing or otherwise was part of:

TCS Amsterdam, the informatics advisory board of the Lorentz Center in Leiden, the Board of Examiners of the ILLC. - Some of my talks are online:

Exponential lower bounds for polytopes in combinatorial optimization, Hypercontractivity in theoretical computer science, Quantum SDP-solvers: Better upper and lower bounds, Quantum algorithms, The potential impact of quantum computers on society, Quantum coupon collector, Improved quantum boosting, Quantum algorithms for optimization, Quantum machine learning from a theoretical perspective. - Fragment from Proust's "A la recherche du temps perdu" on art, life, and death.

*Foundations of Inductive Logic Programming*, Lecture Notes in Artificial Intelligence 1228, Springer, May 1997 (amazon.com link). This is a very theoretical book on ILP. The first part gives a self-contained introduction to the theory of resolution-based theorem proving and logic programming, the second part in-depth covers most of the topics in ILP that we considered of foundational importance for the field. Writing this book took us about two and a half years of sweat and struggle, but I'm still quite happy with the final result (except for a serious error in the appendix to Chapter 18, which was pointed out to us by Chandra Reddy). Krzysztof Apt kindly wrote the foreword to our book, and also put it as review 97-6 on a page of positive reviews. - Contributions to Inductive Logic Programming, my Master's thesis on computer science.

*Ethics and Information Technology*, 19(4):271-276, 2017. arXiv/1712.05380 - Philosophical applications of computational learning theory, my Master's thesis in philosophy. The first part gives a formal "proof" of Chomsky's ideas about the necessity of an innate universal grammar. The second part is about proofs of Occam's razor, which states that you should always select the simplest hypothesis consistent with given data. The thesis also contains a lot of historical and philosophical background concerning these two topics.
