I am a data scientist and biostatistician, with over 15 years of industry and academic experience. I have a multidisciplinary background in statistics, measurement, and research, working within Integrated Delivery and Finance Systems (IDFS), the University of Pittsburgh, and the VA Pittsburgh Healthcare System. I obtained my doctorate in Research Methodology from the University of Pittsburgh, concentrating on advanced statistical methods. I have led the healthcare marketing industry in using statistical methods and Machine Learning (ML) algorithms to design service utilization, cost-savings, and capacity planning models in both the payor and provider space. I mined both patient electronic health record (EHR) and medical claims data to create Custer Lifetime Value (CLV) metrics for a multi-hospital/multi-plan IDFS. The first two years of my academic career has resulted in an immersion of primary and secondary research projects focused on the evaluation of technology, protocols, interventions, and data associated with improving the quality of life in persons with disabilities, Spina Bifida (SB), traumatic brain injury (TBI), spinal cord injury (SCI), chronic lower back pain (cLBP) and stroke. I have collaborated with investigators across multiple disciplines on federally-funded grant applications and currently serve as co-investigator (CO-I) on 11 active projects, totaling over $20 million in research funds. I was recently awarded a VA pilot grant to predict post-TBI recovery trajectories, MH outcomes, and healthcare costs from individual clinical, social determinants of health (SDOH), geographic and treatment level characteristics. In addition, my current research interest and funded work includes: using ML techniques to analyze behavioral and psychosocial outcomes of people with disabilities, creating enhanced data structures by appending socio-geographic and demographic data to existing clinical data, and analysis of randomized controlled trials involving neuro-stimulation and pharmacologics for individuals who have experienced stroke, TBI, and other conditions. I currently serve as the Co-director for the data center and Informatics Core of the NIH HEAL initiative at the University of Pittsburgh, overseeing data governance, monitoring, sharing, and statistical analysis.
