I grew up in Memphis, TN, and with the help and encouragement of many instructors made my way to Yale University. I graduated with my Astronomy & Physics, B.S. in 2009 working with Prof. Hector Arce. In 2016, I finished my doctoral studies on analyzing low signal-to-noise spectra of quasar host galaxies and near infrared detector optimization at the University of Wisconsin-Madison advised by Drs. Marsha Wolf, Christy Tremonti, and Eric Hooper. My current research interests include near infrared detectors, astronomical instrumentation, and applications of machine learning to observational astronomy.
