Collin A. Politsch

Ph.D. Candidate in Statistics and Machine Learning

at Carnegie Mellon University

About Me


I am a Ph.D. candidate in the Department of Statistics & Data Science and Machine Learning Department at Carnegie Mellon University, and also affiliated with the McWilliams Center for Cosmology. The area of research I am most passionate about is the intersection of statistics, machine learning, and cosmology. Much of my Ph.D. work has focused on optimally inverting the silhouettes of the intergalactic medium in the spectra of high redshift quasars to reconstruct one, two, and three-dimensional maps of the Universe's large-scale structure. On a more theoretical level, my interests span various aspects of supervised learning, spatio-temporal modeling, and uncertainty quantification. I am fortunate enough to have three fantastic advisors in Larry Wasserman, Jessi Cisewski-Kehe, and Rupert Croft. I have previously received an M.S. in machine learning from CMU and a B.S. in mathematics from the University of Kansas.

In my free time I enjoy athletics, reading, traveling, any food wrapped in a tortilla, and my dogs -- Seth and Max.

I changed my last name from Eubanks to Politsch in March of 2019 to honor my late mother.
