Equilibrium, coil, and plant design
Open FUSION Toolkit / TokaMaker
A finite-element suite for plasma and fusion modeling, including the TokaMaker free-boundary equilibrium code. I contribute to development, and my students have used it for coil optimization [AIP Adv. 2026], analysis workflows, and porting the FEEQS code.
FUSE
General Atomics' open-source integrated fusion plant design framework. With GA, we used FUSE for more than 200,000 integrated design evaluations comparing positive and negative triangularity plants [NF 2026].
cfspopcon
Commonwealth Fusion Systems' open-source plasma operating contour (POPCON) code. Undergraduate students in my group developed new physics modules, and a related project built a stellarator POPCON code.
Open-source tools in the classroom
FUSE and TokaMaker are the backbone of the design projects in the Fusion Energy Engineering course I plan to teach, so that no student is limited by software licenses.
Data and analysis workflows
Automated kinetic equilibria on HPC
Automated kinetic equilibrium reconstruction and analysis pipelines running at NERSC [FED 2021], which grew into DIII-D's Integrated Research Infrastructure work to bring between-shot analysis from hours to minutes [Frontiers 2025].
Machine learning for fusion data
Neural-network ELM forecasting with Argonne National Laboratory [MLST 2025], multimodal super-resolution diagnostics [Nat. Commun. 2025], and calibrated uncertainty for pedestal predictions (VVUQ post).
