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.
[3] Perez returned to Columbia University as a National Science Foundation postdoctoral fellow, working in the NuSTAR Galactic Center.
[1] She leads the detection program for the general antiparticle spectrometer (GAPS), the first experiment that has been optimised to study low energy antinuclei.
[5][6][7][8] 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.
[1][9][10] 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.
