Expertise: Circumgalactic Medium, Galaxies, Quasar Absorption Line Spectroscopy, Machine Learning




As of May 2019, I have worked with Chris Churchill to analyze metal absorption lines in quasar spectra caused by gas in the circumgalactic medium (CGM) and the intergalactic medium (IGM). My current work centers on the use of machine learning to replace the slow, human intensive analysis process with state-of-the-art, accurate neural networks that can reproduce human-quality work in a fraction of a percentage of the time.
