Dr. Heister is a hard working, dedicated teacher who routinely goes out of his way to help students. As expected for a winner of this award, Dr. Heister’s teaching evaluations have been excellent, despite his teaching of primarily programming-heavy service courses. He has been a great asset to many graduate students over the past few years, as he has put forth tremendous effort helping them use deal.II software (large scale, parallel programming libraries for solving PDEs) for their research. He has also has made a mark in undergraduate education: in 2015, Dr. Heister published a textbook for the MATH3650 course that retails for $20 at the bookstore – the students love both the book and the price.
