Research

Astrostatistics for survey data.

I develop statistical and machine-learning methods for astronomical surveys, with projects in galaxy and IFU segmentation, transient follow-up, spectral classification, Galactic structure, weak-lensing maps, and open research software.

Research Interests

Research directions.

The recurring problems in my papers and software are inference with incomplete data, survey-scale machine learning, transient discovery, segmentation, spectra, cosmic structure, and collaborative infrastructure through COIN.

COIN

Collaborative astrostatistics.

I founded and co-chair the Cosmostatistics Initiative, an international network connecting astronomers, statisticians, computer scientists, and software developers around methodological problems in astrophysics.
