Jop Briët is a postdoc at the Courant Institute of New York University. He received his Ph.D. from C.W.I. and the University of Amsterdam in 2011, under the wonderful supervision Harry Buhrman. He is very grateful to Peter Høyer, who coached him into theoretical computer science and encouraged him to pursue a Ph.D. degree after obtaining B.Sc. and M.Sc. degrees in physics at the University of Calgary. He likes problems that lie in the intersection of theoretical computer science and pure mathematics. He recently started taking yoga classes where he tries handstands and does many downward dogs.
