Research Group

STUDENTS

Carlos Selgas

Carlos Selgas

Carlos Selgas

Carlos is an undergraduate at Penn State University who has been working with me as a Johns Hopkins Rowland Summer Research Fellow. Carlos is applying machine learning tools towards "Clustering Solar Line Morphologies" using NEID Sun-as-a-Star observations.
 

Alia Wofford

Carlos Selgas

Carlos Selgas

Alia is starting as a graduate student at George Mason University this Fall. She has been working with me as a National Astronomy Consortium Fellow & STScI SASP Intern to search for optical, high-resolution reflected light signatures of exoplanets using the NEID spectrograph. 

Team OVERSIGHT

Keck Planet Finder Pipeline Team

Keck Planet Finder Pipeline Team

Keck Planet Finder Pipeline Team

The KPF Pipeline Team is composed of both astronomers and software developers. We are working on a new state-of-the-art in precision radial velocity pipelines, based on best practices in astronomy and modular, open-source, future facing software development.

SALT HRS Precision RV Team

Keck Planet Finder Pipeline Team

Keck Planet Finder Pipeline Team

The SALT HRS instrument has unrealized precision potential behind a 10m aperture. I am guiding an effort to commission the high-stability mode of the instrument, in tandem with a new laser frequency comb, to maximize the exoplanet science possible with this eye on Southern skies.

Previous Students

Elsa Palumbo

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 Wang

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 Ishikawa

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 Weisfeiler

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

Major Collaborations

Keck Planet Finder Science Team

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.

NEID Science Team

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.

NASA-NSF Extreme Precision RV Working 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.

JWST Time Series Working Group

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.

TESS-Keck Survey (TKS)

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.

SPEXS-A Mission Concept

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