About Me

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.

Real Analysis

This course is the first course in a two‐course sequence that provides a theory of the real line, properties of real numbers, and real‐valued functions. Topics include convergence of sequences; open and closed sets; density of sets; Cauchy sequences; monotone convergence theorem; pointwise and uniform convergence of functions; continuity; mean value theorem; intermediate value theorem; compactness; and differentiability.

Exams

• The Final Exam is: Monday Dec 9

Homework:

Be sure to ask me questions in advance.

LaTeX, R, and Matlab

This course provides students some exercises to better their skills in LaTeX, R, and Matlab

First Day Stuff

Differential Geometry

In this class, students will get an introduction in the area of differential geometry. By the end, students should know the basic theory and notation. Students should also know how to do computational tasks in differential geometry.
