• Research Advisor: Cindy RegalResearch Areas: AMO Physics, Precision Measurement, Mechanical Resonators, Optomechanics, & Spin Mechanics
• Studied mass loaded tensioned mechanical resonators using finite element method simulations (COMSOL), analytic calculations, and lab experiments.
• Used eigenfrequency simulations (COMSOL) to calculate the frequency and quality factor of tensioned resonator modes as a function of the load mass.Overall simulation results revealed a previously unknown quality factor.
• Helped with analytic calculations to understand the origin of quality factor saturation in strings and membranes. Generalized the phenomenon toarbitrary geometry tensioned resonators using thermodynamic concepts.
• Developed a method to systematically mass load micromechanical resonators using microscopic magnetic stacking. Worked in an ISO 6 clean room tosuccessfully implement the method on trampoline microresonators.
• Designed, constructed, and aligned a Fabry-Perot interferometer to readout resonator motion with picometer level precision.

Worked on a project related to on-board hydrogen storage and generation under Dr. Suresh Babu. The goal was to engineer cerium based metal-organic framework (MOF) photocatalysts for hydrogen evolution from ammonia borane. Focused mainly on MOF synthesis and characterization, data collection, and analysis.
