Caleb Shor


Ph.D. in Mathematics, Boston University, 2005.
B.S. in Mathematics, Bates College, 2000.
Semester Abroad, Budapest Semesters in Mathematics, Technical University of Budapest, Spring, 1999.


Dr. Caleb Shor is currently a Professor in the Department of Mathematics at Western New England University, where he has taught since 2008. He also serves as director of the PROMYS for Teachers ( program at Boston University. His research interests are in the areas of numerical semigroups, number theory, and algebraic geometry.

Prior to WNE, Dr. Shor was a Visiting Assistant Professor in the Department of Mathematics at Bates College in Lewiston, ME, from 2005--2008.  He received his PhD in Mathematics from Boston University in 2005 with a dissertation titled “On towers of function fields and the construction of the corresponding Goppa codes,” advised by Dr. Emma Previato. As an undergraduate, he went to Bates College and attended the Budapest Semesters in Mathematics program in the spring of 1999.
