James Wicksted Ph.D.

Research Interests
Dr. Wicksted is using noninvasive confocal Raman spectroscopy in order to detect hydration changes of ocular tissue (cornea, lens) as well as to sense the pharmacokinetic behavior associated with ophthalmic drugs applied topically to the eye. Dr. Wicksted is also working on the development of Bragg gratings for applications in wavelength division filtering, optical storage, and for fiber optic temperature and pressure sensor applications.

Additional research projects include characterizing the optical properties of materials utilizing several spectroscopic techniques, such as Raman and Brillouin scattering. Potential applications resulting from these investigations include optical communication devices, acousto-optic devices, and optical limiting devices.
