Christopher Overstreet

Christopher Overstreet is an Assistant Professor at the Miller Department of Physics and Astronomy at Johns Hopkins University (JHU), where he leads the Overstreet Lab. He joined JHU in 2023 following a Bloch Postdoctoral Fellowship at Stanford University (2021–2023). He holds a Ph.D. in Physics from Stanford University (2020) and an A.B. in Physics and Mathematics from Harvard University (2013).

His research focuses on atomic, molecular, and optical (AMO) physics, particularly using ultracold atoms and molecules to probe fundamental physics questions such as baryon asymmetry, dark matter, and gravity-quantum mechanics interplay. The Overstreet Lab develops advanced atom interferometry techniques to conduct precision measurements, including long-baseline interferometry and tests of the equivalence principle at unprecedented accuracy levels.

Key experimental tools include laser systems with Stark-shift-compensated dual beam splitters and ytterbium atom interferometry for dark matter searches. His work bridges theoretical models with cutting-edge experimental setups, with contributions to gravitational Aharonov-Bohm effects and superposition states at macroscopic scales.

Current lab members include graduate researchers Michalis Panagiotou, Rose Ranson, and Yifan Zhou, along with undergraduate researchers such as Yarin Camacho Aparicio and Jack Drouin. The lab is located in Bloomberg 366, part of the Department of Physics & Astronomy at JHU’s Homewood campus.
