Brief Bio

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.

Research Interests

Near infrared instrumentation

Astrophysics: Technology & Missions

Near infrared detector arrays and their controllers and optimization.

Galaxy evolution

Astrophysics: Galaxies

How galaxies change with time, specifically determining galaxy star formation histories from spectra.

Machine learning and statistics

Astrophysics: Analysis

Using new tools like diffusion k-means and other advanced algorithms to understand multi-dimensional and complex data.

Exoplanet spectroscopy

Astrophysics: Extrasolar planets

Developing and assessing technology capability to acquire direct spectroscopy of exoplanent atmospheres to look for biosignatures.
