Research Interests

Computer assisted instruction, electron paramagnetic resonance and electrochemical studies of organic free radicals

The University at Buffalo General Chemistry program contains a substantial CAI (computer assisted instruction) component. Many of the computer programs used in General Chemistry were developed in my laboratory. Thus, interested graduate students working in the teaching program had the opportunity to become involved in developing these educational materials.

The department has a well equipped modern EPR (electron paramagnetic resonance) facility which my students and I used to study the structure and reactivity of organic free radicals. Transient radicals are normally generated electrochemically and then studied by EPR spectroscopy as they leave the electrode surface. Thus information about the adsorption-desorption process and the effects of the electrical doublelayer on radical structure are also available by combining EPR and electrochemical studies.
