About Us

Physics is everywhere. It's in everything we do. If you want to know something about the natural world, physics has the answers. 

Our group probes the inner workings of atoms and the brain through computational research in atomic collisions, ultrafast physics, and neuroscience.  

We use high performance computing and physics to answer questions such as: 

"How do electrons move in and around atoms?

"How do twisted light and twisted matter interact?"

"What cellular mechanisms cause and contribute to migraines?"
