Mary Gregg (Fed)
Mathematical Statistician
Mary Gregg received a M.S. and a Ph.D. in Biostatistics from the University of Louisville, where her dissertation work focused on reweighting methods that correct for informative cluster size and informative intra-cluster group sizes in the analysis of clustered observations. Mary joined NIST in the fall of 2020 as a National Research Council postdoctoral associate, and as a permanent employee in 2022. Her work at NIST includes interdisciplinary research relating to forensics, wireless communication, and statistical machine learning applications.
