Joel W. Robbin is a mathematician at the University of Wisconsin at Madison. His thesis was in mathematical logics, under A. Church of Princeton; he also authored a textbook on logics and coauthored Mathematical logic and computability with Jerome Kiestler.
From soon after his thesis, Robbin switches his main interests to dynamical systems of Morse–Smale type where he found several foundational results. He also worked in related questions of rigorous approaches to quantization, symplectic geometry and symplectic topology; several of his articles are coauthored with Dietmar Salamon.
At the time when MatLab was expensive for students, Robbin programmed an interpreter for a small subset MINI MatLab free for student’s use and accompanying his undergraduate textbook on algebra; more recently he translated that subset to a java version.
