Survey Science | Galactic Archaeology
I use large astronomical surveys to study how galaxies form and evolve, to discover new and unusual phenomena, and to reconstruct the history of the Milky Way through Galactic Archaeology.
Research
Galactic Archaeology
Reconstructing the Milky Way's assembly history from stellar positions, motions, and chemistry.
Stellar Halo and Satellites
Mapping streams, dwarf galaxies, and other low-surface-brightness structures around the Milky Way and other galaxies.
Surveys and Inference
Using major photometric, spectroscopic, and astrometric surveys with statistical and machine-learning methods.
Featured Work in the Media

Antlia 2
A very diffuse satellite galaxy discovered behind the Milky Way disc.
Field of Streams
Maps of tidal debris and substructure in the Galactic halo.
Gaia, Clouds, and Bridges
Tracing stellar structures associated with the Magellanic Clouds.
