Dr. Slatyer explains how dark matter –the mysterious 85 percent of the matter in the universe—continues to elude scientific understanding. She describes how dark matter collisions might create observable signals, and how we can attempt to pick out those signals from telescope observations.

Prof. Slatyer has led innovative theoretical research on scenarios where the dark matter couples to much lighter particles, and hence may experience long-range forces; her work has helped inspire a broad experimental program to search for such particles. Awards include the 2017 Henry Primakoff Award for Early-Career Particle Physics by the Division of Particles and Fields of the American Physical Society; and the 2014 Bruno Rossi Prize of the American Astronomical Society.
