Current Research

• Characterizing quantum dots using TEM, EDX and photoluminescence.

Previous Research

• Used second-harmonic generation to characterize the nonlinear optical properties of organic thin films.
• Characterized small, integrated lens/scanner devices and waveguides.
• Used second-harmonic and sum-frequency generation techniques to study the thermodynamics of adsorbates on model surfaces and in porous media.
• Did vibrational spectroscopy at surfaces and in porous media using a tunable mid-infrared laser beam generated by optical parametric generation (OPG).
• Investigated the thermodynamics of soil samples that have undergone laser ablation.
