Precision Lab for Dark Matter: My current research is focused on developing techniques for precision measurements of dark matter. We are adapting techniques from the exoplanet community (extreme-precision radial velocity observations), pulsar timing, and of eclipsing binary stars, to develop time-series precision measurements of the accelerations of stars, which gives the most direct probe of the mass distributions in galaxies. These recent measurements now enable the new, highly interdisciplinary field of “real-time” Galactic dynamics that brings together the exoplanet community, researchers in compact objects and eclipsing binaries, and in traditional Galactic dynamics.
