Stephanie Earnshaw, PhD, is Vice President of Health Economics at RTI Health Solutions. Dr. Earnshaw applies mathematical modeling, optimization, and decision-analysis techniques to industry-related issues and health care problems. Her areas of specialization include systems optimization and solving resource allocation problems. She has developed innovative mathematical models to determine pricing strategy and to assess impact to budgets and cost-effectiveness of health technologies in cardiovascular disease, gastrointestinal disorders, chronic obstructive pulmonary disease, transplantation, infectious disease, osteoporosis, and men's health. Standard mathematical modeling techniques performed include Markov models, Monte Carlo simulation models, and other state transition models. These analyses have been used to support not only pharmaceuticals, but also diagnostics and medical devices. She has also developed innovative mathematical programming models to determine allocations of HIV prevention interventions and trainers and field representatives to training sites. Dr. Earnshaw has experience in quality management, machine scheduling, linear and integer programming, network optimization, stochastic modeling, and personnel-assignment models. She is a member of the International Society of Pharmacoeconomics Outcomes Research and the Institute for Operations Research and the Management Sciences. She has presented her work at professional conferences and has published in several peer-reviewed journals, including Annuals of Internal Medicine, Archives of Internal Medicine, Medical Decision Making, Respiratory Medicine, Value in Health, Journal of American Society of Nephrology, Stroke, and Pharmacoeconomics.
