As theoretical physicists...

We aim to understand the phenomenology of plasma in the laboratory and in the cosmos. We use mathematical models and computer simulations to explain how plasmas move, interact with magnetic fields and boundaries, and evolve on various scales.

Working with collaborators in the U.S. and around the world, we advance fundamental physics concepts that guide experiments and project applications, such as the development of magnetic fusion energy.

News and Announcements


Machine learning simulation at San Diego Supercomputer Center

FAPPG Machine Learning Research in the News

We're pleased that our recent Physical Review E publication on using machine learning to better understand turbulence density and viscosity was featured by UC San Diego News. This piece highlights the collaboration between our research group and the San Diego Supercomputer Center, which provides the immense processing power needed for these machine learning applications.


Fluid Mechanics Webinar Series hosted by The Journal of Fluid Mechanics

The Journal of Fluid Mechanics is organizing an interesting webinar series. We hope you'll take a look! (Note: Registration is required for first-time attendees.)
