Dark matter, the invisible substance that outweighs everything we can see by five to one, is the glue that holds together the universe’s largest structures. Yet to understand dark matter, physicists must look to the opposite extreme of scale: the physics of subatomic particles. Scientists sift through the flood of cosmic particles arriving at Earth from ordinary astrophysical processes, searching for the faint signatures of dark matter interactions. This talk explores how the search for dark matter connects the tiniest constituents of matter to the largest structures in the cosmos, and how new detector technologies are opening fresh windows onto one of the biggest mysteries in science.
About the Speaker
Kerstin Perez is originally from West Philadelphia and earned her B.A. in physics from Columbia University. She received her Ph.D. from Caltech, for research using the ATLAS detector at the LHC. She then returned to Columbia University as an NSF Astronomy and Astrophysics Postdoctoral Fellow. She was appointed as an Assistant Professor of Physics at Haverford College, before joining MIT as an Assistant Professor of Physics in 2016 and an Associate Professor of Physics in 2021. She returned once again to Columbia University as faculty in 2022. She has won numerous awards, including a Sloan Research Fellowship, Cottrell Scholar Award, APS DPF Early Career Instrumentation Award, and MIT School of Science Teaching Prize for Undergraduate Education. She is the daughter of Louis Antonio Perez, who earned his J.D. at Columbia University in 1970, and Diann Carlson Perez, who worked as a juvenile public defender for the city of Philadelphia.
