Ronald Freiwald, Ph.D., professor of mathematics, specializes in topology and set theory. The hole stays despite the other changes.
Topology is one of five or six basic branches of mathematics.
Of course, it gets more abstract and goes off in different directions from this simple description. The non-mathematician might think that Freiwald himself is a bit of a study in topology. Natasha and Boris sister and brother, share Freiwald's home. He's been very active advising mathematics students and molding the departmental curriculum. In 1992, he received a Distinguished Faculty Award from the University's Alumni Board of Governors at Founders Day ceremonies.
