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.

Congratulations to Sinan Oral, one of FAPPG's undergraduate student researchers. On November 22, UC San Diego's Division of Physical Sciences announced that Sinan was selected as a recipient of a Dean's Undergraduate Award for Excellence.
Sinan's research project focuses on the problem of turbulent transport and confinement transitions in a weakly stochastic background magnetic field. The study is motivated by the goal of reconciling good confinement and good boundary control — a central issue for magnetic fusion and ITER.
Join us via Zoom for a series of seminars on all areas of plasma physics and related fields, hosted by UC San Diego, UC Irvine, UC Los Angeles, and the DIII-D Burning Plasma Physics Group.
Due to the pandemic, an in-person Festival de Théorie has been postponed until June 2022.
Instead, a virtual Festival de Théorie Lecture Series will be held this year. The organizers and your colleagues hope to see you online!

Zoom meetings: Contact Guilhem Dif-Pradalier at firstname.lastname@example.org for Zoom meeting information and to receive Festival announcements.
Congratulations to Justin Tahmassebpur, one of FAPPG's undergraduate collaborators. On June 3, UC San Diego's Jacobs School of Engineering recognized Justin with a 2020-2021 Electrical & Computer Engineering Best Undergraduate Research Award.
Justin's research analyzed how fan-generated turbulent jets diffused clouds of virus particles in poorly ventilated rooms. Justin found that diffusion reduced peak virus concentrations to levels where people were no longer at risk of infection. Future applications of this work could help curb the risk of COVID-19 virus infection in indoor settings.
Congratulations to our fellow group member, Robin Heinonen, who defended his Ph.D. thesis via Zoom on February 24.
Robin's work has focused on plasma turbulence, avalanching, and zonal flows. Be sure to check out Robin's defense presentation. We look forward to future collaborations with Dr. Heinonen!

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.
