TEACHING EXPERIENCE
I have taught over a wide range in the physics curriculum over the years. Since 2000, courses taught include:
PSC 101 (Physical Science - a general elective with no prerequisites); PHYS 201 (algebra-based physics, first qtr.);
PHYS 253 (calculus physics for engineers, third qtr.); HTC 297T and 298T (calculus physics for honor students);
HTC 397T and 399T (modern physics for honor students); PHYS 416/516 (mathematical phys.); PHYS 611–612
(two qtrs. of graduate quantum mechanics); PHYS 623 (graduate statistical mechanics); PHYS 732 (condensed
matter phys.); PHYS 736 (quantum many-body physics). My evaluations in courses above 300 are excellent (A
and A–), while in lower level courses they are at or above the average for the department (≈ B+). I am continuously working on improving my lectures by fine tuning quizzes and assignments, incorporating “just-in-time”
teaching techniques, “personal response” activities, as well as increasing the number of “hands-on” experiences
during class. I enjoy teaching and the challenges it represents.
