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.

Festival de Théorie 2021 banner

Festival de Théorie 2021 Lecture Series —
June 1 to July 2, 2021

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!

Learn more about Festival de Théorie 2021 Lecture Series.

Justin-Tahmassebpur

Well done, Justin!

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.


Robin Heinonen with Eifel Tower in background

Well done, Robin!

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!

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.
