I received my PhD in Mathematics at Washington State University in April 2013. Prior to finishing my PhD, I took 6 years off from graduate school. During that time I worked at Walla Walla Community College as the Director of Instructional Support and as an adjunct Math Instructor. I also spent one year teaching High School in a small town called Helix, Oregon. I even spent a semester at the University of Miami in Florida (which was so not my favorite place to live). I received my Master's Degree in Mathematics from Kansas State University in 2000 and I received my Bachelor's Degree in Mathematics (with a Physics minor) from Eastern Oregon University in 1998.

I love the outdoors. In fact, each of the background pictures is a place outdoors that I loved so much I had to capture with my camera. One day, I want to go backpacking in the wild for at least a month. That would be my dream vacation. I also love sports: running, soccer, volleyball, snowshoeing, skating (ice and roller).. but I'm not great at any. I also crochet, but just for fun. I love to Batik. I'm sure you've seen some of my work.

This course will focus on solving differential equations and modeling real‐world phenomena using differential equations. Students will develop techniques to solve differential equations, including separation of variables, variation of parameters, method of characteristic roots, undetermined coefficients, power series, and Laplace transforms.

This course combines MATH 147A and MATH 147B into a single course. Topics covered in this course include polynomial functions (division of polynomials, zeros of polynomial functions, complex numbers, the fundamental theorem of algebra), rational functions, exponential functions, logarithmic functions, and elementary matrix operations. Both the right‐triangle and unit‐circle approaches to trigonometry are covered along with trigonometric identities, graphs of trigonometric functions, solving trigonometric functions, the law of sines, the law of cosines, vectors, and polar coordinates.
