Bio: Alvin Garcia is an ORISE FES Postdoctoral Research Fellow in the Plasma Control Group at Princeton University. He completed his PhD in Physics at the University of California, Irvine and his thesis was on Spin Polarized Fuel and Artificial Intelligence using data from the DIII-D National Fusion Facility. The AI part of his thesis was in collaboration with Kolemen and supported by the U.S. DOE SCGSR Fellowship. As a postdoc, he plans to design, propose, and lead experiments aimed at controlling dangerous Alfvén eigenmodes using machine learning-based methods on DIII-D.

Research Title: Machine-learning based profile prediction using fast-ion diagnostic data on DIII-D
Bio: In 2020, after receiving his bachelor's in nuclear engineering from the University of Tennessee in Knoxville (UTK), Felipe Novais joined Professor G. Ivan Maldonado's (UTK) group and completed his Master's and PhD in nuclear engineering. During his graduate school studies, Felipe had the privilege to spend time working only on fusion neutronics, which allowed him to gain knowledge and several skills in Monte Carlo radiation transport methodology on fusion nuclear devices. Recently, he was awarded the U.S. Department of Energy Fusion Energy Sciences Postdoc Fellowship and joined MIT to support the development of neutronics studies of the SPARC tokamak using OpenMC.

Dr. Rebecca Masline 2023
Bio: Rebecca Masline completed her PhD at the University of California San Diego in 2023, studying the physics of tokamak plasma exhaust in alternative divertor configurations using 2D multifluid edge simulation codes. She is continuing and expanding upon her thesis work during her ORISE fellowship, where she is using computer simulations to validate, study, and predict the behavior of injected helium in existing nuclear fusion experiments and helium ash in reactor-relevant regimes, with a focus

Dr. Todd Elder 2023
Bio:Todd Elder has been involved in plasma physics research since his first summer internship at Los Alamos National Laboratory. Inspired by the concept of "tiny nuclear generators" - a complete nuclear-based generator of power no bigger than a walnut - from Isaac Asimov's the Foundation series, he has been pursuing the simplification of stellarator coil sets, the single most complicated and expensive part of the device. While not wrestling with the difficulties of these three-dimensional devices, he enjoys cycling, olympic weightlifting, and the simple pleasures of life.

Dr. Monica Gehrig - 2022
Bio: Monica Gehrig is a postdoctoral researcher supporting the Fusion Energy Division at Oak Ridge National Laboratory. She graduated with her PhD from the Missouri University of Science and Technology Nuclear Engineering and Radiation Science Department in the fall 2022 term. Her work involves heat transfer and mass transport simulations for helium flowing in tritium breeding blankets using both 3D computational fluid dynamic Reynolds Averaged Navier Stokes turbulence modeling and 1D thermal hydraulic modeling.
