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 provides students with the tools to perform calculus on functions of several variables. This is the third course in a three‐course sequence. This class is intended for students in engineering, mathematics, and the sciences. Topics include vector algebra and geometry; functions of several variables; partial and directional derivatives; the gradient; the multivariable chain rule; optimization; multiple and iterated integrals; parametric curves and surfaces in 3‐dimensions; vector fields; divergence and curl; line and surface integrals; Green’s theorem; Stokes’ theorem; and the divergence theorem.
