Faculty and Staff


Aryal, Dr. Saroj
Assistant Professor
  LA 839



Ph.D. in Mathematics, University of Wyoming (2013); M.S. in Mathematics, University of Wyoming (2011); B.S. in Mathematics, Trinity College (2009)


Dr. Saroj Aryal joined MSUB in 2013. He enjoys teaching a range of courses in mathematics. His main objective in teaching is to present mathematical concepts in the simplest way possible. His primary research interest is sparse moment problem, which deals with missing moment data. It has very deep and broad application since data obtained from physical experiments and phenomena are often corrupt or incomplete. He is enthusiastic about getting undergraduate students involved in his research projects. Dr. Aryal grew up in Nepal before coming to U.S. for college in 2005. Outside mathematics, he enjoys hiking, swimming, and travelling around the world visiting different cultures.

Chen, Dr. Oliver Y.K.
Professor of Mathematics
  LA 842



Ph.D. in Mathematics, University of Washington (1983); M.S. in Mathematics, National Tsing Hua University (1973); B.S. in Mathematics, National Taiwan Normal University (1969)


Dr. Chen has been teaching at MSUB since 1983. He grew up in Taiwan before coming to U.S. for Ph.D. at Washington University. Dr. Chen enjoys teaching courses in mathematics and computer sciences. His main objective in teaching is to guide students with correct concepts, simplest formulas, the most effective methods and algorithms. His research interest is in pure and applied mathematics as well as computer sciences.

Chih, Dr. Tien
Assistant Professor
  LA 838



Ph.D. in Mathematics, University of Montana (2014); M.A. in Mathematics, University of Montana (2009); B.A. in Mathematics, University of Hawaii at Hilo (2007)


Dr. Tien Chih has been teaching at MSUB since 2017. He grew up in Hilo, Hawaii before coming to Montana for graduate school. His interests include undergraduate research (contact him if you're interested!), Mathematical Outreach, Technology in Math Teaching \& Research, Cooking. Dr. Chih enjoys teaching across the spectrum of Mathematical courses from the Abstract to the Applied. His favorite part of teaching is getting students to see past the noise and grasping the concepts underneath. His research area is Algebraic and Categorical Graph Theory. He studies functions between networks, and the structures that they form. This also extends to applications if they're entertaining enough.

Hoover, Dr. John
Associate Professor
  LA 833



B.A., Coe College, 1972; M.S., Northern Arizona University, 1973; Ph.D., University of Utah, 1978


Jacobson, Dr. Mark
Dept. Chair; Professor, Mathematics
  LA 836



Ph.D. in Electrical Engineering, University of Colorado (1996); M.S. in Electrical Engineering, University of Colorado (1985); B.S. in Electrical Engineering, Montana State University (1980)


Dr. Mark Jacobson has been teaching at MSUB since 2004. He likes teaching Applied Mathematics. He finds it wonderful to see students make connections between Math and everyday applications. Dr. Jacobson's research area is electromagnetic remote sensing of the Earth's cryosphere. In particular, he uses reflected GPS signals (this technique is known as GPS Interferometric Reflectometry) to estimate snow depth, snow density, snow water equivalent (SWE) and lake ice thickness. Solutions of Maxwell's Equations (coupled linear partial differential equations) are the theoretical basis for this work. In his spare time, Dr. Jacobson enjoys hiking, backcountry skiing, snowshoeing, mountain biking, fly fishing, and spending time with pet rabbits.
