Career

In 1974, Statman received his Ph.D. from Stanford University for his Ph.D. dissertation, supervised by Georg Kreisel, entitled Structural Complexity of Proofs.^[1] His achievements include the proof that the type inhabitation problem in simply typed lambda calculus is PSPACE-complete,^[2] lower bounds on simply typed lambda calculus,^[3] logical relations,^[4] and intersection types.^[5] He was a co-author of the book Lambda Calculus with Types.^[6]
