Karen Isabel Perez
William J. Welch Postdoctoral Fellow
Biography
Karen I. Perez first set her sights on a PhD in Astronomy in 8th grade after discovering the field of SETI while watching science documentaries with her dad. In 2019, she earned her B.A. in Astronomy with a concentration in Astrophysics from Cornell University, where she found her calling in radio astronomy during a course with Prof. Jim Cordes. That same year, Karen joined the Berkeley SETI Research Center (BSRC) REU program under the mentorship of Dr. Vishal Gajjar, where she helped test pulsar search pipelines and develop the observing strategy for the Breakthrough Listen (BL) Galactic Center Survey to search for both astrophysical signals and technosignatures. This work earned her the 2020 SETI Forward Award.
Karen began her PhD in Astronomy at Columbia University in Fall 2019 under Prof. Jules Halpern. Her thesis focuses on multi-wavelength (especially in the radio) searches for pulsars in both the Galactic field and center, targeting redback and transitional millisecond pulsars in the field, as well as canonical and millisecond pulsars near the supermassive black hole at the heart of the Milky Way. She has also continued collaborating with the BL team for the past six years and has co-mentored REU students, leading surveys of the Galactic Center and Plane using the Green Bank, Parkes, and Sardinia Radio Telescopes. Karen is a recipient of the Gates Millennium Scholarship (2015-2025), which has supported her studies from college through graduate school.
Technical Description of Work
As the Jack Welch Postdoctoral Fellow at the SETI Institute, Karen will develop real-time, machine learning and GPU-accelerated analysis pipelines for detecting single-pulse transients, as well as narrowband and broadband technosignatures using the Allen Telescope Array in Hat Creek, CA. Primarily a scientist, her research will bridge science and engineering by diving into radio instrumentation and NVIDIA GPU technology. She will begin her fellowship in Fall 2025 and hold a Visiting Scholar postdoctoral appointment at the University of Arizona.
