Faculty & Staff

The mathematics and computer science faculty are teacher-scholars who are dedicated to teaching and developing courses for their students. If you can, drop by and see us in action. Poke your head into any of our offices and you're likely to find a student or two. They know they are always welcome—just ask them.

She also has her master's in mathematics with an emphasis on Financial Mathematics. Her research interests are mathematical biology, mathematical modeling, and financial mathematics. She teaches Calculus, Differential Equations, and Applied Mathematics courses.
Richard Vitray, Ph.D.
Professor & Chair of Mathematics
Bush 114B
Rick Vitray earned his Ph.D. in mathematics from Ohio State University. He plays basketball and soduko, reads Joseph Conrad, Dostoyevsky, and the New York Times, and listens to Branford Marsalis, Miles Davis, Joni Mitchell, and Bob Dylan (among others). In his spare time, he teaches mathematics and investigates questions in graph theory.
Jay Yellen, Ph.D.
Professor of Mathematics
Bush 373
Jay Yellen earned his Ph.D. in mathematics (group theory) from Colorado State University. His interests include graph theory (he co-wrote two books) and operations research. He starts his day with J.S. Bach, listens to the blues and early jazz, takes part in math haiku contests with Mathematics Professor Mark Anderson, and loves going to art museums (ask him about 'Art with Jay').


Donata Nutter
Administrative Assistant
Bush 110
Donata Nutter originally worked for Rollins from 1987-1994, first as Administrative Assistant for History and Political Science, and then as Executive Assistant to the Dean of Hamilton Holt School. While she pursued other career paths after leaving the college, she never stopped thinking about Rollins and wanting to return. She finally got her wish in October 2012, when she was hired by the Department of Mathematics and Computer Science. Donata is thrilled to be back at Rollins!
