The Invisible Chase

Just over 100 years ago, physicists stumbled upon an elementary particle that could answer questions about the origin of the universe. Elusive and nearly massless, neutrinos may be the solution to understanding everything from the Big Bang to the inner workings of the atomic nucleus — and UNC physicist Julieta Gruszko can’t stop chasing them.

Cooperation Over Competition

Flocks of birds. Schools of fish. Colonies of ants. Their strength is in numbers as they can fend off larger predators, move faster, and mate more easily. Daphne Klotsa, an applied physicist, studies how these biological swarms function in hopes to improve how humans and automated technologies navigate the world.

Daphne Klotsa is an assistant professor in the Department of Applied Physical Sciences within the UNC College of Arts & Sciences. She studies the physics of swarms — systems that exhibit emergent collective and cooperative behavior such as flocks of birds, schools of fish, and crowds of people — in order to engineer similar systems composed of moving parts, from self-propelled nanoparticles in solution to cars in traffic.

Derrick Carr

Derrick Carr is a PhD student in the Department of Physics and Astronomy within the UNC College of Arts & Sciences. He searches for rare, compact galaxies called nuggets and strives to understand how they form and evolve.

Kate Richardson

Kate Richardson is a junior and Chancellor’s Science Scholar double-majoring in physics and computer science within the UNC College of Arts & Sciences. She researches dark matter and how it might be composed of hypothetical elementary particles called axions.
