Faculty Research Areas
John Brooks
John Brooks, PhD, is a health economist with a focus on estimating treatment comparative
effectiveness using practice based treatment variation. He has a Ph.D. in economics
from the University of Michigan and was a Service Fellow at the Agency for Healthcare
Research and Quality and a Professor at the University of Iowa prior to coming to
the University of South Carolina. Dr. Brooks is the Director of Center for Effectiveness
Research in Orthopaedics (CERO) which is a collaborative effort between the University
of South Carolina and the Greenville Hospital System to promote comparative effectiveness
research (CER) in orthopedic care. His research has focused on tackling the theoretical
and empirical issues surrounding CER, and the CERO offers an extraordinary opportunity
to further develop these methods in a clinical practice context with little controlled
trial evidence. It is clear that proper treatment inferences from CER require a full
understanding the factors underlying treatment decisions. The CERO will meld theoretical
models of treatment choice with advanced methods to better understand the factors
underlying treatment choices and the outcome implications associated with these choices.
Cole Champman
Cole Chapman, PhD, is a health economist with a focus on econometrics and methods
for making inferences using observational databases. Dr. Chapman’s recent research
focuses on assumptions underlying researchers’ ability to estimate patient-centered
treatment effect (TE) concepts with the purpose of clarifying the conditions necessary
for making inferences on TE heterogeneity and alternative TE parameters using instrumental
variables (IV) methods. Dr. Chapman is interested in studying and explaining, in simple
terms, the theoretical limitations of statistical tools and further awareness of these
limitations so that evidence appropriately informs practice. Dr. Chapman earned his
BS in Economics and PhD in Pharmaceutical Socio-Economics from The University of Iowa.
Dr. Chapman is currently involved with research on patient preferences and variation
in interventions for orthopedic conditions.
Brian Chen
Brian Chen, JD, PhD is an assistant professor in the Department of Health Services
Policy and Management at the Arnold School of Public Health, University of South Carolina.
Dr. Chen’s research focuses on health policy and the impact of incentives in health
care organizations on provider and patient behavior. Dr. Chen comes to the Arnold
School of Public Health not only with a multidisciplinary law and economics background,
but also with an international perspective. He has a particularly intimate knowledge
of the Taiwanese health care system from his experience as an assistant to the hospital
administrator at a medical college in Taiwan. Since joining the faculty at the Arnold
School of Public Health, Dr. Chen has conducted empirical research related to providing
care to diabetic patients in China, effects of legal and financial incentives such
as malpractice liability, FDA policy on drug safety, and payment reform. His work
also focuses on comparative health systems and health service delivery globally, a
theme that encompasses the historical evolution of health policies; organizational
innovation, contracting, and soft budget constraints; and chronic disease management
and service coordination for aging populations. Dr. Brian Chen completed his Ph.D.
in Business Administration at the Haas School of Business, University of California
at Berkeley. He received a Juris Doctor from Stanford Law School in 1997, and graduated
summa cum laude from Harvard College in 1992. Dr. Chen is also the Associate Director
of the Taiwan Doctoral Program housed in the Department of Health Services Policy
and Management.
Elizabeth Crouch
Elizabeth Crouch, PhD received her Ph.D. in Policy Studies (December 2012) and M.S.
in Applied Economics and Statistics (August 2010) from Clemson University. Dr. Crouch
was appointed as a research assistant professor in the department of Health Services
Policy and Management in June 2015. Dr. Crouch’s scholarly interests have focused
on the intersection of public health and incentive structures. Dr. Crouch was recently
a co-investigator on a six month randomized control trial at Anmed Health Medical
Center, analyzing the effects of social media and weight loss advice on obesity in
adults. Dr. Crouch has also directly examined interventions aimed to improve maternal
and child health. One of Dr. Crouch’s recent publications determined the likelihood
of immunization uptake among pre-school age children in the United States. This was
undertaken to better understand how incentives might further increase immunization
rates among minority populations. Additionally, Dr. Crouch’s research on the state
Medicaid population provided estimates of the cost-savings to healthcare payers of
improved infant outcomes from maternal health interventions.
Melanie Cozad
Melanie Cozad, PhD is an assistant professor in the Department of Health Services
Policy and Management and the Center for Effectiveness Research in Orthopedics at
the Arnold School of Public Health, University of South Carolina. Dr. Cozad’s research
primarily focuses on quantifying how changes within the health care industry affect
hospitals, hospices, and home health agencies. She comes to the Arnold School of Public
Health with an applied microeconomic background in health care and the environment
after having spent three years as an assistant professor at Furman University. Dr.
Cozad also served five years in the United States Marine Corps. Dr. Cozad has conducted
empirical research related to the implications of the Affordable Care Act on hospital
utilization, capacity, the workforce, and its profitability as well as how effective
hospices and home health care agencies are in delivering palliative care to children.
With other colleagues at the Arnold School of Public Health, she is also working on
a project that develops a valid and efficient approach to measure the preferences
of individual patients over patient reported outcomes that effectively integrates
these measures into the care process. Dr. Cozad completed her Ph.D. in Economics at
the University of Tennessee, Knoxville (UTK) in 2012. She also earned an M.A. in Economics
from UTK in 2010, an MBA from Cameron University in 2007, and a B.S. in Economics

framework with an emphasis on Community Based Participatory Research. Dr. Glover’s
research skills and training combined with her strong business management/organizational
behavior background, have led to the successful direction and management of several
comprehensive NIH and DoD center awards over the past ten years. Her current research
addresses the lack of African-Americans participating in clinical trials to reduce
and eliminate stroke disparities.

in epidemiology from the Ohio State University in 1984. His research interests are
in healthcare practices and policies, especially those relating to neurological disorders
and stroke, that improve health outcomes. Of note, findings from his epidemiologic
research into the cause of the outbreak of amyotrophic lateral sclerosis among veterans
of the first Gulf War resulted in a change in VA benefits policy.
