Taylor 208

Education: Ph.D., Mathematics, University of Colorado at Boulder, 1991. B.A., Mathematics, Linfield College, 1986, Summa cum Laude.

Dr. Bricher's research interests are in the area of nonlinear-partial differential equations, which can be used to model a myriad of physical phenomena. A few examples are: neuron activity, thermal combustion and flame propagation, the microstruture of metals, turbulence and weather patterns. He has published several papers on mathematical problems related to combustion, and has presented his work at national and international mathematics conferences. Dr. Bricher teaches a course in nonlinear differential equations and dynamical systems that prepares students to work with him on collaborative research projects. Projects in the past have culminated in student presentations at national mathematical meetings. He regularly teaches courses in calculus, analysis, differential equations, and probability and mathematical statistics. He advises physics theses and often helps science students with their mathematical questions. Dr. Bricher enjoys advising students that share an interest in mathematics.

Dr. Dunn's research interests are in graph theory and combinatorics. In graph theory, he focuses on competitive graph coloring algorithms. He has worked with a number of student collaborators, both at Linfield, and as a part of an NSF-funded REU-RET, partnering with Jennifer Nordstrom (2008, 2009, 2012, 2014), and Michael Hitchman (2013).

Taylor 212

Education: Ph.D., Mathematics, University of Oregon. B.A., Mathematics, Swarthmore College.

Dr. Hitchman's research interests are in the areas of topology and geometry. He has more recently been interested in the interplay between topology and geometry in the area of cosmic topology, whose aim is to detect the shape of the universe. He has also participated in collaborative research with students on tiling questions. He enjoys teaching a wide range of courses, including calculus, topology, geometry, analysis, probability and statistics, and astronomy.

Taylor 205


PhD University of Oregon MS University of Maryland, Baltimore County BS university of Redlands

Dr. Nordstrom's research interests are in the areas of algebra and combinatorics. She received her Ph. D. in ring theory from the University of Oregon. Dr. Nordstrom primarily teaches Abstract Algebra, Discrete Math, Number Theory, and Game Theory but maintains an interest in a wide variety of mathematical fields such as graph theory and number theory. She is currently involved in research with undergraduates in the area of combinatorial game theory.

Mathus Hall/Taylor 214

Education: PhD, Mathematics Education, Oregon State Univeristy, 1999, MSEd, Mathematics Education, Western Oregon State College, 1985, BA, Mathematics, Linfield College, 1975 Magna cum laude

Dr. VanCleave's current interests are in undergraduate mathematics education and mathematics teacher preparation. She works with both preservice and inservice teachers. Her recent research is on student discourse in mathematics classrooms. The Oregon Mathematics Leadership Institute (OMLI) has provided a perfect venue for pursuing this interest.Her dissertation research focused on the beliefs and practices of high school teachers and the use of graphing calculators. First year courses such as Intermediate Algebra, Precalculus, and Finite Math With Calculus along with Statistics and Mathematics For Elementary Teachers compose the bulk of Dr. VanCleave's teaching load. She also has an interests in Operations Research and History of Math. As a mathematics educator, she advises many of Linfield's prospective high school math teachers.
