Bio

Dr. Richard Hasenauer joined Northeastern State University's faculty in 2015 as an Assistant Professor of Mathematics in the Department of Mathematics and Computer Science. Since then he has been promoted to the rank of Associate Professor, and served as the Department Chair of Mathematics and Computer Science for a time.

Education:

  • PhD, Mathematics, North Dakota State University, 2012
Commutative Algebra, Factorization Theory, and Number Theory
I enjoy teaching a broad range of classes in mathematics and statistics. I especially like teaching modern algebra and doing research projects with students.

  • A characterization of non-Noetherian BFDs and FFDs (Journal Article, Academic Journal), Discovery, Published, 2017
  • Class (semi)groups of Prufer domains and atomicty (Journal Article, Academic Journal), Discovery, Published, 2021
  • Factorization properties of Prufer domains (Journal Article, Academic Journal), Discovery, Published, 2018
