Data reduction development for Keck/HISPEC

The High resolution Infrared Spectrograph for Exoplanet Characterization (HISPEC) is a upcoming R~100,000, y to K infrared, fiber-fed spectrograph planned for commissioning at Keck Observatory in late 2027. Science cases will include stellar radial velocities, and both on- and off-axis spectroscopy of planetary atmospheres.

As part of the preparation for HISPEC’s commissioning as a facility instrument, I am a part of the development team for the HISPEC data reduction pipeline (DRP). I’ve lead development of detector image simulations currently being used for end-to-end testing of the DRP before on-sky data are available.
