As an applied statistician / econometrician and Data Scientist, I develop and apply analytical models to very large data sets in a variety of disciplines, I created the Kronos Retail Labor Index, an economic indicator of the health of the US retail market and economy, as well as R3M (Relative Readmission Risk Monitor), an application used at UVA to predict which recently discharged patients are most likely to be readmitted. I have a high degree of skill and experience in the use of SAS (including Enterprise Miner), SPSS, EViews, R, Mathematica, PEPA, among other tools. The range of techniques that I have used includes; Survival Analysis, Interactive Markov Chain Models, Time Series Econometric Models, Neural Networks, Bayesian Probability Nets, Random Forest Categorization Models, and dozens of others. I have managed teams of analysts/economists and taught MIS at the University level. I have been involved in the early stages of several startups. In my current position at the UVA Medical System I am developing new techniques in the field of Statistical Learning that focus on predicting patient outcomes based on historical and demographic information. This enables care providers in prioritizing care interventions to maximize patient well being will reducing costs Specialties: Big Data, Statistics, Econometrics, Data Mining & Discovery, Data Visualization, Six-Sigma, Lean Enterprise

Senior Data Scientist @ As a member of the analytics team in the Accountable Care Organization and Patient Population analysis group, I develop predictive models targeting patient outcomes over time. By being able to predict which patients in a particular population are most likely to be readmitted to the hospital, or otherwise suffer deteriorating health, it is possible to focus limited resources in a more optimized way. This approach to using Big Data in healthcare is central to the promise of the Affordable Care Act.
