معرفی
Brett H. Andrews is a Research Professor in the Department of Physics and Astronomy at the University of Pittsburgh, specializing in astrophysics and cosmology. He holds a Ph.D. and M.S. in Astronomy from The Ohio State University (2014, 2011) and a B.S. in Astronomy & Physics from Yale University (2008). His academic appointments include Research Associate Professor (2022-present), Research Assistant Professor (2017-2022), and Postdoctoral Associate (2014-2017) at the University of Pittsburgh.
Research Focus
Dr. Andrews develops machine learning and statistical techniques to improve photometric redshift estimation for large-scale astronomical surveys including the Nancy Grace Roman Space Telescope and Vera C. Rubin Observatory Legacy Survey. His work encompasses:
- Deep learning photo-z models and uncertainty quantification
- Spectroscopic dataset construction and bias mitigation
- Galaxy cross-correlation calibration methods
- Baryon acoustic oscillation measurements with DESI-2
Collaborations & Training
He actively collaborates with the Roman HLIS Cosmology Team, Roman Science Collaboration, LSST DESC, and DESI. Since 2020, he has organized annual Python Boot Camps training undergraduates and early PhD students in astronomical programming and data analysis techniques.
Student Advising
Dr. Andrews mentors graduate and undergraduate researchers in astrophysics and data science. Notable former students include Biprateep Dey (now postdoc at University of Toronto), Catherine Fielder (postdoc at University of Arizona), and Zach Lewis (NSF GRFP Fellow at University of Wisconsin).
