I make membranes out of self-assembling polymerizable surfactants to investigate the interplay of structure-property relationships and the motion of charged particles within assembled species. This work is focused on the physics of membranes designed for nanoparticle filtration, salt separations, organic separations, and fuel cells. I am a part of the VIEST seed group focusing on ordered nanofiltrations. Additionally, I was a recipient of a 2022-2023 VIEST Fellowship.
My specific research skills include structure identification through transmission and grazing-incidence small-angle x-ray scattering (SAXS/GISAXS) and materials property classification through dielectric spectroscopy (DS) and dynamic mechanical analysis (DMA), with proficiency in a gamut of methods (DSC, TGA, UV-Vis Spectroscopy, etc.). I also enjoy any technique that involves imaging.
