Ross Kang and I will be looking to hire one postdoc based at TU Delft, in the Discrete Mathematics & Optimization group, co-supervised with Ross Kang (University of Amsterdam).  

We recently also advertised two PhD positions, one in Amsterdam and one in Delft. I do not expect to take any further PhD students in the near future. See also https://staff.fnwi.uva.nl/j.r.kang/M2PhDcall.html.
