Dr. Grant Tremblay

NASA Einstein Fellow | Yale University

 

About Grant

I am an observational astrophysicist and NASA Einstein Fellow at Yale University. Previously, I was a Fellow in the Directorate for Science at the European Southern Observatory (ESO) near Munich, and an astronomer at ESO's Very Large Telescope in Chile. Prior to that, I was at the Rochester Institute of Technology, the Space Telescope Science Institute, the Johns Hopkins University, and the University of Rochester. A short bio can be found here

I work on star formation and the dynamics of multiphase gas amid energetic feedback from active galaxies, whose central engines are powered by accreting supermassive black holes. 

You can download my full curriculum vitae (CV) here. Feel free to email me at grant.tremblay (at) yale.edu. 

Support for my work is provided by the National Aeronautics and Space Administration (NASA) through Einstein Postdoctoral Fellowship Award Number PF-150128. I have also been funded by NASA Grants stemming from the Hubble Space Telescope, Chandra X-ray Observatory, and Spitzer Space Telescope missions. I am also grateful for partial support from the European Community's Seventh Framework Programme. Views expressed here are my own, and not those of NASA, Yale, or ESO.
