Bio

David W. Hogg is the Senior Research Scientist for the Astronomical Data Group at the Flatiron Institute’s Center for Computational Astrophysics. His research has ranged across fundamental cosmological measurements, galaxy formation at high redshift, stellar dynamics in the Milky Way, precise measurement of stellar element abundances, and extra-solar planet discovery and characterization.

His work includes a significant engineering component, in areas of instrument calibration, automated data analysis, and statistical inference. He is a developer and supporter of open-source software projects and open-data initiatives. He is the chair of the Sloan Digital Sky Survey V Advisory Council and he is a member of the Board of the Terra Hunting Experiment. He has appointments in the NYU Center For Cosmology and Particle Physics, the NYU Center for Data Science, and the Max Planck Institute for Astronomy in Heidelberg, Germany. Hogg joined New York University in 2001 and the Flatiron Institute at its founding in 2017.

A model of the stars in the GD-1 stellar stream overlaid on data collected by the Gaia spacecraft. The color of each stat represents how strongly its orbit was affected by the unknown dark matter substructure of the galaxy. White represents a significant change from normal, while red represents almost no difference
