About my research:
My work pertains to determining structural characteristics of functional materials by synchrotron diffraction. To increase the productivity during these experiments I have automated Rietveld analysis to provide structural characteristics of experiments on-the-fly. This is important within the field as many materials structural processes progress on the order of <1%, undetectable by eye, over the course of a day. Rietveld analysis is sensitive to changes we wish to see on the sub 0.01% scale and in many cases enables quantification of experimental progress, kinetics, and structural evolutions in real time.
My current research is on increasing the performance of lead metal halide materials by comprehensive structural analysis. This work is done within the Stone Group at SSRL Materials Sciences Division. This is done primarily using synchrotron X-ray diffraction at beamlines 11-3 and 2-1 at SSRL and has supplemental analysis with PDF studies at 11-ID-C and XAS studies at various SSRL beamlines.
Other previous experience within this work has been in ion conductive processes within the Khalifah Group at Stony Brook University. These include cathode and separator Li-ion mobility in operanodo/in situ Li-metal batteries, in situ ion exchange, and modeling of thick cathodes using MAPLE in collaboration with the Subramanian group at UT Austin.
