My work, in a nutshell, is all about waves: ultrasonic, acoustic, electromagnetic and optical. My students and I use waves to perform materials characterization (electromagnetic and mechanical) and we study the fundamental physics of waves in random media. The applications of our work include everything from landmine detection to the basic properties of amorphous semiconductors to how telescopes detect the far infrared light that makes up most of the electromagnetic energy in the universe. Since I do both theoretical and experimental work, there is ample opportunity for undergraduates to get involved in meaningful research and even publish papers.
