Research and Teaching Interests
Computational Physics: I use Python for all my computing needs, as well as for teaching Physics 261: Computational Physics. I have been working on a text for the course, but my work is morphing into creating a set of useful projects to be used as assignments.
Torsion Pendulum Magnetometer: My former student (Cody Goolsby; now a Ph.D. candidate at UMass Amherst) and I have designed a torsion pendulum that will be used to measure fluctuations in the horizontal component of the earth's magnetic field. This apparatus is under construction with two new students: Nicholas Anna and Alexander Knight. Lot's of good physics in this experiment!
Granular Physics: A while ago, I spent time studying the stick-slip dynamics of a two dimensional array of cylinders. We looked at the statistics of stick-slip events as well as rotational motion within the array.
Physics Education: My main inspiration for physics education came from reading the works of Carl R. Rogers (Freedom to Learn and it's revisions). I have been incorporating authentic assessment and conceptual questioning into my introductory physics classes. In addition, I am working on a plan to have our physics majors act as Learning Assistants in our introductory courses (based on the Univ. of Colorado Learning Assistants program).
