About Rick Klima

After earning his PhD at North Carolina State University, Dr. Rick Klima spent time as an instructor at NC State, a cryptologist at the National Security Agency, and a professor at the State University of New York at Oswego, before coming to Appalachian State University in 2002.

Klima's research interests include applications of linear and abstract algebra, primarily in cryptography and error-correcting codes, and the mathematics of voting theory. He is the author of several books in these areas, in collaboration with co-authors from NC State, Radford University, and Grand Valley State University. He has also directed 11 master's capstone projects, 8 senior honors theses, and a study abroad program in these areas with students at Appalachian.

In addition to being a Professor in the Department of Mathematical Sciences, Klima is also the Director of the First Year Seminar program at Appalachian.
