B.A., Physics, Johns Hopkins University, 1986
M.S., Acoustics, Penn State University, 1991
Ph.D., Acoustics, Penn State University, 1995
These are the classes that I teach on a fairly regular basis:
Other courses I have taught:
- PHYS 101 Introductory Astronomy
- PHYS 111-113 Introductory Physics
- STEP 301 Bridging Seminar I - Research Opportunities
- STEP 302 Bridging Seminar II - Research Skills
I have also taught courses in the Douglas Honors College and the Science Honors program.
My primary area of interest and expertise is physical acoustics, which is the study of mechanical waves and related phenomena. I am interested in waves of all kinds, from sound waves in a trumpet to sonic booms to tsunamis; that such disparate phenomena are united by similar mathematics is especially intriguing. My background is primarily theoretical and computational, but most of my projects with students involve pairing experiments with computer models to investigate wave behavior. I am looking forward to developing an experimental acoustics laboratory with an anechoic chamber in the new Science II building.
Recent and current projects include:
- modeling sonic booms from maneuvering aircraft (funded by NASA)
- experimental and computational investigation of the effect of internal pressure on the resonance frequencies of a spherical aluminum shell (the goal is to develop a noninvasive method for monitoring intracranial pressure)
- experimental and computational study of wave behavior in a tensegrity mast
- measuring and modeling wind turbine noise
Another area of interest is the epistomological basis of science, the role of science and society, and how to improve scientific literacy and understanding among non-scientists. I am interested in the ways in which society develops its perceptions of science, including the perseverance of pseudo-scientific and unscientific beliefs. My main work in this area is developing curriculum at the university level that specifically addresses our understanding of how science works and why this is important.
