MFE-IM Team

MFE-IM is a group of the Magnetic Fusion Experiments (MFE) division of the MIT Plasma Science and Fusion Center (PSFC). We are a team of scientists, postdoctoral researchers and graduate students, and we host visiting and undergraduate students to carry out short-term cutting-edge projects with us. We actively collaborate with other groups at the PSFC and from the worldwide fusion energy community.

Nathan Howard (he/him, nthoward@psfc.mit.edu) is a principal research scientist at the MIT PSFC and leads the Performance and Transport group, formed as part of the MIT/CFS collaborations. Nathan’s research interests lie in multi-scale gyrokinetics, impurity transport validation, high performance computing and machine learning enhanced transport models. Nathan actively collaborates with the DIII-D tokamak, where his team operates the laser-blow off system to study experimental impurity transport.

Aaron Ho

Research Scientist

Aaron (he/him, aaronkho@mit.edu) is a research scientist working at the MIT PSFC. Aaron’s research combines plasma transport knowledge with machine learning techniques to build fast surrogate models, with the aim of using them in the design and operation of tokamak devices

Anne White

PROFESSOR, Associate VPR

Anne E. White (she/her, whitea@mit.edu) is the School of Engineering Distinguished Professor of Engineering at MIT. Her current research is a focused US DOE funded effort on core-to-edge turbulence-transport research and study of ELM-free regimes at ASDEX Upgrade, supported by the development of Correlation Electron Cyclotron Emission Diagnostics (CECE) and coupled radiometer and reflectometer measurements. She and her students also perform research funded by private companies CFS and nT-Tao, in the area of transport physics and diagnostic development.
