Dr. Sabrina Stierwalt is an extragalactic astrophysicist. She uses nearby, interacting galaxies to understand how stars and galaxies formed throughout the universe's history. She uses data from space-based telescopes like Hubble, Spitzer, and XMM-Newton, along with data from ground-based telescopes like ALMA, the VLA, and Magellan. Most recently, she was awarded a multi-year grant from the National Science Foundation to conduct the first systematic study of the gas dynamics and star formation in interacting dwarf galaxies, smaller galaxies which are the building blocks of more massive ones like our Milky Way.

She also works to make science and the stars more accessible. She does this with her weekly science podcast Everyday Einstein and through a program to bring an inflatable planetarium to communities across Los Angeles that are under-represented in STEM.
