2026 Sagan Summer Workshop

Exoplanets with Roman Surveys: Microlensing and Transits


July 20-24, 2026

Hosted by The NASA Exoplanet Science Institute

California Institute of Technology, Pasadena, CA

#sagan2026


The 2026 Sagan Summer Workshop will focus on "Exoplanets with Roman Surveys: Microlensing and Transits." Timed to prepare for the launch of the Nancy Grace Roman Space Telescope no later than May 2027, this workshop will concentrate on the exoplanet science from the Roman Galactic Bulge Time Domain Survey (GBTDS). The GBTDS, one of the three Core Community Surveys that Roman will perform, will discover thousands of planets towards the Galactic bulge through both the microlensing and transit detection techniques. The workshop will cover the methodologies, opportunities, and expected results from the surveys, including synergies with other ground- and space-based observations. We will also cover additional science that the GBTDS is expected to yield, as well as the exoplanet science expected from the Roman coronagraph.

The workshop will be hybrid, with both in-person and remote attendance. The Sagan Summer Workshops are aimed at advanced undergraduate students, graduate students, and postdocs; however, we welcome attendees at all career stages. There is no registration fee for these workshops.

This website will be updated as more information becomes available.
