Research Experience
- Graduate Research Assistant - McGill University (2016-2022)
- Quantifying the properties of quark-gluon plasma using state-of-the-art physical models with Bayesian inference for the first time. My PhD work focused on using the best available models of heavy ion collisions, combined with methodological improvements to the Bayesian inference used in the field. Additional time is spent as a member of the JETSCAPE Collaboration’s Simulations and Distributed Computing Working Group.
- Undergraduate Student Researcher - The College of William & Mary (2013-2016)
- Undergraduate honors thesis using computational methods (Python, Fortran) to probe Big Bang Nucleosynthesis for limits on Beyond Standard Model physics. This work was performed under the direction of Andre Walker-Loud.
- Stirling Cycle Analyst for Nuclear Space Power Applications - NASA Glenn Research Center (2015)
- LERCIP Intern with the Thermal Energy Conversion Branch working to improve model fidelity and performing simulations for the Test Demonstration Unit (TDU) for the pre-testing Test Readiness Review. Additional work was done to optimize Stirling engines to map power density-efficiency space and customize the piston-displacer waveform. Future applications of this work include deep space and space exploration applications as passive power units
- REU Student - Texas A&M University and Cyclotron Institute (2014)
- National Science Foundation (US)-funded studentship under Ralf Rapp studying hot and dense hadronic matter, resulting in a state-of-the-art parametrization of thermal photon production in hadronic matter.
