About me
I am a Senior Scientist in the School of Data Science at the University of Virginia (UVA). During my first years at UVA I focused on applying simulation-optimization techniques to challenging problems in the military domain, some of which were a direct continuation of work I had started while working as an Industrial Engineer at the U.S. Army Research Laboratory located at Aberdeen Proving Grounds in Maryland (from 2011-2013). More recently I have begun to focus on applying machine learning methods to difficult predictive problems in the healthcare domain.
Prior to working at UVA I worked as an Industrial Engineer for the U.S. Army Research Laboratory, Aberdeen Proving Grounds, Maryland. At ARL my primary role was building simulation models to estimate the maintenance burden of proposed Army systems, and then comparing this estimate to the maintenance burden of the system being replaced. While at ARL I initiated the development of a decision support tool for Army Fuel planners, a project which I continued to work on during my initial time at UVA.
I received my Ph.D. in Industrial Engineering from the Edward P. Fitts Department of Industrial & Systems Engineering at North Carolina State University in May 2011. My co-advisors were Dr. Thom Hodgson and Dr. Kristin Thoney-Barletta.
I received my Master of Operations Research degree from NC State in May 2008.
I attended the College of William & Mary for my undergraduate where I received a Bachelor of Science in Mathematics in May 2006.
Research Interests
I enjoy applying Operations Research techniques and methods to various application domains. I have built agent-based simulation models, stochastic discrete event simulation models, and simulation-optimization models for
- Strategic fuel planning at theater entry points
- Operational fuel planning in-theater
- Designing Army patrol districts
- Worker allocation in a dual resource constrained job shop
I am also interested in data science and predictive modeling problems and have worked on projects to
- Estimate the prevalence of obesity in Virginia's Thomas Jefferson Health District
- Optimize dosing for end stage renal disease (ESRD)-induced anemia
- Predict pedestrian risk of injury based on vehicle front end design
Examples of my data visualization work can be found here.
I program primarily using Python, and use Pandas, Numpy, and Scipy for my data analysis needs.
