Research
I have a broad interest in Nanoscience and Technology, especially the spectroscopic, acoustic, and electron microscopic characterization of technologically important materials including carbon nanotubes, Bi nanorods, quantum dots, photonic crystals, rare earth laser materials, and nanoBIOmaterials.
Undergraduate students (Physics Majors and non-Majors) with specific interest in materials science, spectroscopy, biophysics, chemical physics, etc. are welcome to visit the Applied Physics Research Lab or contact me for details.
