# Kerstin Perez

Kerstin Perez is an associate professor of Particle Physics at the Massachusetts Institute of Technology. She is interested in physics beyond the standard model. She leads the silicon detector program for the General AntiParticle Spectrometer (GAPS) and the high-energy X-ray analysis community for the NuSTAR telescope array.

## Early life and education

Perez was born and raised in West Philadelphia. She studied physics and mathematics at Columbia University, earning an undergraduate degree magna cum laude in 2005. She moved to the California Institute of Technology for her graduate studies, earning a master's in 2008 and a PhD in 2011. She developed the ATLAS experiment pixel detector, and led the first ATLAS measurements of the inclusive cross-section for the production of hadronic jets. Perez returned to Columbia University as a National Science Foundation postdoctoral fellow, working in the NuSTAR Galactic Center. During her fellowship she developed outreach activities for the Columbia University Double Discovery Centre.

## Research and career

Perez joined Haverford College as an assistant professor in 2015, before moving to Massachusetts Institute of Technology in 2016. Her research interests lie in physics beyond the standard model. She leads the detection program for the general antiparticle spectrometer (GAPS), the first experiment that has been optimised to study low energy antinuclei. Perez is interested in anti-deuterons, antiproton-antineutron pairs which may provide evidence of the annihilation of weakly interacting massive particles, a candidate for dark matter. The GAPS detection is particularly novel, including over 1,000 large-area, low-cost lithium-drifted silicon detectors made by Perez, which can monitor exotic atom capture and decay. The GAPS experiment uses long-duration balloons and reaches the upper atmosphere.
Alongside her work on GAPS, Perez leads the high-energy X-rays analysis group for the NuSTAR telescope array. NuSTAR has revealed how stellar remnant populations vary as you move from the Galactic Center. This helps Perez identify sterile neutrinos, which could help to explain neutrino oscillation.

### Outreach and advocacy

Perez is an advocate for improved diversity in science, and supports students from underrepresented groups to study and research physics. She is concerned that women and people of colour often carry an unnecessary burden in the scientific workplace. She is involved with public engagement through the Massachusetts Institute of Technology, supporting their massive open online course in electricity and magnetism.
