Professor Mauro graduated from Bates College in 1976 with a B.S. in Mathematics. From there, he attended S.U.N.Y-Binghamton, receiving his MS and PhD degrees (both in Mathematics) in 1978 and 1981, respectively. Joining Trinity's faculty in 1982, he went on to earn a second MS in Computer Science from R.P.I. in 1988.

Trained primarily in probability and statistics, Professor Mauro has since turned his research attention to graph theory;  particularly, vertex labelings associated with frequency assignments to transmitters. He considers himself to be extremely fortunate to have found a friend and collaborator in Professor John Georges, also a Trinity faculty member.

Professor Mauro's philosophy of teaching holds simply that without clarity and economy of presentation, mathematics can easily turn from an object of immense beauty to a pit of deep despair. He thus prepares for each lecture by asking (and answering) two basic questions: What do I want to say?  How do I want to say it?
