Jefferson Morris Gill (born December 22, 1960) is Distinguished Professor of Government, and of Mathematics & Statistics, the Director of the Center for Data Science, the previous Editor of Political Analysis, and a member of the Center for Behavioral Neuroscience at American University as of the Fall of 2017.
Most sophisticated Bayesian models for the social or medical sciences require complex, compute-intensive tools such as MCMC to efficiently estimate parameters of interest.
Gill is an expert in these statistical and computational techniques and uses them to contribute to empirical knowledge in the biomedical and social sciences.
He also contributes to gene-wide associate studies (GWAS) that seek to discover correlated cancer genes related to obesity, diet, and exercise, as well as consult on computational genetics analysis.
Other work includes Bayesian hierarchical models, Markov chain Monte Carlo theory, bureaucratic behavior in national security agencies, and issues in political epidemiology.
