surveys and observing programs
the large team efforts and telescope time behind my research
Big questions in astronomy are rarely answered by one person with one telescope. Most of my work happens through large collaborations that pool years of telescope time and share the resulting data widely — the surveys below are the major ones I help lead, followed by the individual observing programs I’ve contributed to.
Major Surveys
- UNCOVER/MegaScience Survey (2022–)
Photometry and Catalog lead - Euclid Consortium Deep Field Survey (2018–)
LBG Work Package co-lead, US/NASA high redshift coordinator - Cosmic Dawn Survey (2018–)
Project Co-lead, Photometry and Catalog co-lead - Cosmic Evolution Survey (2018–)
