Research Interests
Our research is focused on two areas:

(1) Catalysis of the electrochemical reduction of carbon dioxide, and the photochemical "splitting" of carbon dioxide.

(2) "Ultrafast" electron transfer dynamics in inorganic mixed valence complexes.

Catalysis of the electrochemical reduction of carbon dioxide. The goal of these studies is to utilize CO2, an abundant greenhouse gas, for the ultimate manufacture of energy dense liquid fuels. These efforts have concentrated on CO2 activation and reduction of CO2 by chemical, photochemical, and electrochemical means, and the development of catalysts for transforming CO2 to organic products. Catalysts which can manage multiple proton coupled electron transfers (PCETs) to CO2 to form liquid fuels such as methanol are being developed. We are employing semiconductor devices with appropriate band energies to photochemically "split" CO2 to CO and O2.



A class of inorganic charge transfer complexes with electronic structures that can be tuned from completely delocalized to tightly localized is under investigation. At the delocaization limit, rates of intramolecular electron transfer in these systems can be so fast that coalescence of infrared spectral features occurs in a manner reminiscent of dynamic NMR, but on a picosecond (vs. millisecond for NMR) time scale. The dynamics probed by this simple IR method track solvent dipolar response, and can be developed as "reporters" of local dynamics. We expect that the fundamental knowledge gained can be applied to the rational design of "electronically wired" metal complexes and "molecular devices".

Outreach Activities
The lab is multi-racial, multi-cultural, and 40% female overall. Having a diverse lab does help in keeping it that way, but there are other activities at a more individual level that have, I believe, brought a more diverse population into science in general, and my lab in particular. These involve simply being accessible to students in the lower division classes that I teach (Chem 6C and Chem 6CH) and encouraging them to consider what they might become with a career in science, and, if there is interest, to introduce them to graduate students or other undergraduate students in a research setting to see what it looks like, and then if they like what they see to give them a chance to try it out. I would say that all of my current undergraduate students were exposed to opportunities that they never imagined, and are benefiting from mentoring and an environment that shows that rich intellectual rewards can be found in a laboratory, and many others from diverse backgrounds are doing remarkable things there.
