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.

  • The Final Exam is: Monday Dec 9


Be sure to ask me questions in advance. I will not accept late assignments starting Sept 2.

Past Homework

LaTeX, R, and Matlab

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

Integrated Science

This course is a team-taught, place-based course designed to provide an introduction to multiple scientific disciplines, including biology, chemistry, computer science, earth science, mathematics, and physics around the theme of the greater Lewiston-Clarkston valley watershed. Course content is integrated in order to allow the students the opportunity to use multiple scientific disciplines to understand the world in which they live. Weekly laboratories will be used to provide students with hands on learning experiences that directly related to the topics covered in lecture and may include field experiences. The course will include emphasis on college reading, college writing, collaboration, and using math to solve real world problems. This course is designed for science majors who place into intermediate algebra, however, any student is welcome to contact the instructor(s) for permission to enroll in the course.

Class Assignments and Labs

  • Lab 5
  • Lab 2
  • HW 3Due September 4 at noon
  • Lab 1Due September 10 no later than 3pm (don't be late for lab)
  • Email Lloyd with an answer to the following: What units make sense to measure meteor crater? What units do not make sense to use? Justify your answers. Use complete sentences and be clear. Due Monday, August 26, before class begins.
  • Don't forget to email me telling me you saw this before noon on Tuesday Aug 20.

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.
