The one day Utrecht Combinatorics Workshop which will take place on 7 November 2014, on the campus of Utrecht University. 
Teaching
In the academic year 20142015, I will be teaching the
course Advanced Combinatorics (joint with Ross Kang),
the Master Seminar Stochastics (joint with Roberto Fernández), the "honours seminar", and the first year undergraduate course Inleiding Kansrekening en Statistiek (WISB161).
In the fall of 2015, the highly succesful course Probabilistic and Extremal Combinatorics will again be offered though mastermath.
Research
I work in combinatorics and probability. My research interests include graphs in various flavours (random, extremal, coloured, fractional), percolation, discrete and stochastic geometry, random matrices, asymptotic and probabilistic combinatorics and combinatorial games.
Here are preprint versions of some of my research articles.

Past workshop organization
For nostalgic reasons, I still maintain a link to the website of the Stochastic Acitivity Month on Combinatorics and Probability which took place in January 2014. (Activities included a workshop on "Probability and Graphs" and minicourses on graph limits, analysis of Boolean functions and Probabilistic aspects of Minimal Spanning Trees); a link to the website of the Utrecht Graphs Workshop which took place on Thursday 31 October and Friday 1 November 2013; the website of the STAR Workshop on Random Graphs that took place in Utrecht on 1 and 2 November 2012, the website of a workshop on probabilistic and algebraic methods in discrete mathematics that took place in Amsterdam on 6 December 2010, and a link to the webpage of the Postgraduate Combinatorial Conference 2005 that took place on 2123 March 2005 in Oxford.
