Research Group

Elsa worked with me in the summer of 2019 as  Freshman Summer Research Fellow at Caltech. She developed a tool to create stellar masks for RV cross-correlation based on empirical measurements from single-shot spectra, and demonstrated performance equivalent to the gold-standard ESPRESSO masks.

Qifan was a Schmidt Academy Post-Baccalaureate Fellow at Caltech working on the KPF Pipeline. Given his software engineering background, Qifan led a lot of the early architecture work, as well as setting up industry standard practices for code contribution, documentation, and testing.
 

Yuzo was a Master student at San Francisco State University, who worked on multiple KPF subsystems including the chromatic exposure meter, and the Ca H&K spectrometer.

Marie was an undergraduate at UC Berkeley who worked on simulations to enable design decisions for the KPF Ca H&K spectrometer subsystem.

The KPF Science Team is a worldwide collaboration to execute large-scale cutting-edge exoplanet and stellar science with KPF. As Project Scientist for KPF, I formed and lead the science team. I am currently planning commissioning and early science, with the first round of KPF proposals due soon.

The NEID Science Team executes the Guaranteed Time Observations (GTO) Survey as a legacy of the instrument team. I will lead a section of the GTO Program at STScI as well as individual Guest Observer (GO) programs with my own group.

Ahead of the 2020 Decadal Survey, NASA and NSF jointly commissioned a community-based “Extreme Precision Radial Velocity (EPRV) Working Group” (EPRV-WG) to develop a blueprint for a strategic EPRV initiative. I am a member of the WG and co-chair of the Data Analysis Subgroup.

Cross-instrument working group to ensure fidelity in time series observations using the James Webb Space Telescope. I am the NIRISS lead, examining impacts from instrumental systematics like 1/f noise and non-linearity corrections.

TKS is a collaboration across multiple institutions to conduct ground-based follow-up of candidates from the TESS exoplanet hunting satellite. I am a co-Investigator of this program, which has been awarded some of the largest time allocations in the history of Keck and Lick Observatories.

Spectrophotometric SmallSat mission concept to characterize stellar activity. I am the  Chair of the Science Advisory Committee.
