Bon voyage to Jeroen!
Jeroen has finished his PhD thesis! Congratulations on this accomplishment, and we wait anxiously (well, not very anxiously, it's a pretty good thesis) to hear what his evaluation committee says. Meanwhile, Jeroen will spend his next few months backpacking in Asia before starting a postdoc position at Brown University in the Fall. He'll be back shortly thereafter to defend his thesis and we'll give him a proper farewell then.
