Dr. Yoon’s research focuses on the study of galaxy evolution using advanced statistical analysis methods. He has worked on development of galaxy morphology analysis tool using Bayesian MCMC. While in George Mason as a postdoc, he has worked with Dr. Rosenberg on statistical analysis of galaxy gas properties in groups and clusters, using combination of SDSS and ALFALFA data. He is also working on the QSO absorption line systems in and around the groups and clusters. In 2014, he moved to the Leiden observatory in the Netherlands to work on ALMA.
