The Fusion and Astrophysical Plasma Physics Group (FAPPG) at University of California San Diego studies the physics of plasma—hot, ionized gas—with the aims of advancing fusion energy and humankind’s understanding of the universe.

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.

This website offers information about our group members, research activities, and publications. We invite you to browse it and to contact us with any questions.
