I am currently a fellow in the Department of Energy Fuel Cell Technologies Office within the Office of Energy Efficiency and Renewable Energy. I am working in the area of fuel cell R&D, with particular focus on heavy duty fuel cell electric vehicles.
In 2019 I completed my PhD at Cornell University in the lab of Professor David Muller, where I studied materials for electrochemical energy conversion and storage devices, including batteries and fuel cells, using transmission electron microscopy and electrochemistry. My PhD research projects included investigating the performance and durability of proton exchange membrane fuel cell catalysts using scanning transmission electron microscope (STEM) imaging, 3D electron tomography, and electron energy loss spectroscopy (EELS); developing improved techniques for electron tomography of nanoparticles; and investigating the atomic and electronic structure of lithium ion battery materials with atomic-resolution STEM imaging, EELS, and nanobeam electron diffraction (NBED).
