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.

UC San Diego is pleased to announce the formation of a new Department of Astronomy and Astrophysics within the School of Physical Sciences.
Prof. Diamond will serve as one of the 12 founding faculty members. This new department will leverage the University of California’s substantial existing investment in astronomical facilities to support students in reaching their full research and learning potential.
Research and instruction will cover a broad range of areas, from the evolution of the universe and the first stars to galaxy and planet formation and cosmology. The department will also play a key role in developing instrumentation for the Keck Observatory, Lick Observatory, the Thirty Meter Telescope, the Simons Observatory, and the Compton Spectrometer and Imager (COSI).

FAPPG graduate student Mingyun Cao was awarded a 2022-2023 Friends of the International Center Endowed Fellowship. The Center's fellowship supports UC San Diego graduate students in conducting research or study abroad activities that enhance their academic experience and foster friendship, understanding and cooperation in the international community. Congratulations, Mingyun!
Congratulations to FAPPG undergraduate student Taurean Zhang, who won a 2022 Malmberg Award from UC San Diego's Department of Physics. The John Holmes Malmberg Prize is presented annually at commencement to a graduating physics student who is recognized for potential for a career in physics and a measure of experimental inquisitiveness. Brilliantly done, Taurean!
Congratulations to FAPPG Ph.D. student Fredy Ramirez, who was awarded a 2021-2022 UC San Diego Physics Department Distinguished Graduate Teaching Award.
This award recoginizes first- and second-year graduate students for outstanding performance as a teaching assistant. Many congratulations, Fredy!
