Research Interests

 Analytical Chemistry: Vibrational Spectroscopy, Laser Spectroscopy, Chemometrics and Electrochemistry. My primary interests involve the development of novel methodologies, especially those using optical spectroscopy, for qualitative and quantitative analysis to solve difficult chemical problems. I am especially interested in the coupling of vibrational spectroscopy (both infrared and laser Raman spectroscopy) and optical imaging to gather chemical information remotely.
