DePoy heads the Munnerlyn Astronomical Instrumentation Lab, building high-throughput spectrographs and precision photometric-calibration systems (DECam/DECal for the Dark Energy Survey, VIRUS for HETDEX, GMACS for the Giant Magellan Telescope). A strong astronomy pivot where detector/spectrograph sensitivity is the enabling technology.

Marshall builds astronomical spectrographs and calibration systems in the Munnerlyn Lab; co-PI of GMACS (Giant Magellan Telescope) and project scientist for the Maunakea Spectroscopic Explorer, leading instrumentation for DES and HETDEX. Astronomy pivot driven by high-precision spectral/photometric instrumentation.
