I believe that the most important challenges that society faces is the development of sustainable energy technology. Many solutions to this problem, in both energy generation and storage depend on tuning the electronic and mechanical properties of materials. To this end I am interested in the development of high-throughput computational tools for materials discovery.
My current research interests revolve around the development of tools for creating and using high-throughput computational materials databases. These tools have been used successfully screen for several different applications. The first study, which used a pre-alpha version of these tools involved searching for Li anode materials in the family of transition metal silicides, stannides and phosphides. It was subsequently used in a much broader search for Li-O reactions involving lithium metal oxides for an interesting new reaction found by Trahey et al.

In addition to electrochemical properties, I have been involved in a search for new precipitates for BCC strengthening. Using a search space of common ordered structures, we have started a search based on thermodynamic stability, lattice mismatch and abundance. Several compositions of industrial interest have already been identified, and this search paradigm is now being applied to additional structural materials.

Although my current research is theory based, using density functional theory, my previous work was in the experimental characterization of hydrogen storage materials. I worked for Dr. D.J. Liu at Argonne National Laboratory for two years, contributing to research leading to two papers and an undergraduate thesis. My thesis documented the development of an in-house Sievert's apparatus for measuring hydrogen uptake in 100-200 mg samples in various cryogenic environments as well as at room temperature. In addition, I developed software tools to fully automate measurement and data analysis.
My undergraduate degree is a B.S. in Applied Physics, from Kettering University (formerly GMI) in Flint MI.
