Research Interests

My research projects investigate the reliability of conventional silicon PV modules and new-generation perovskite modules, which is important as we make the shift to renewables and away from fossil fuels! The conventional silicon PV reliability project is in collaboration with NREL and Sandia National Labs, with the following techniques used: adhesion testing, DSC, FTIR, Soxhlet extraction (gel content), gel permeation chromatography, rheometer-DMA, and computational fracture mechanics modeling. I also help out with the modeling side for the perovskite reliability projects.

Feel free to check out the projects that I’m working on below, and reach out if you'd like to discuss getting involved with the group or have questions on mechanical and polymer testing. In my free time, I like to compete in open water swimming, longboard down hills, play tennis, check out tattoo art, and listen to rock music.
