She is also interested in program evaluation methodology and decision analytic tools.

Ilene has worked as a program specialist at the Office of the National Coordinator for Health Information Technology. She was the 2013-2014 Johns Hopkins Center to Eliminate Cardiovascular Disparities Research Fellow and the Centers for Population Health and Health Disparities Cross-Center Research Fellow where she is working on a mixed-methods approach to quantifying the costs of a complex intervention targeting disparities in hypertension. She is the award recipient of the 2014 Charles D. Flagle Award and the Lee Lusted Student Prize in Decision Psychology and Shared Decision Making.

Eric Roberts, PhD candidate

Eric is a Health Economics and Policy PhD candidate in the Department of Health Policy and Management. His research interests include Medicaid and health care use among low-income adults; housing and health; and measuring health care quality and quality disparities. Underlying these research areas is his interest in econometric methods, and integrating techniques from statistics, biostatistics and econometrics to better understand the use of non-experimental data in health care settings. Eric's research has been funded by the Jayne Koskinas Ted Giovanis Foundation for Health and Policy, the Commonwealth Fund and the Aetna Foundation. He has also worked on contract research projects through the Johns Hopkins Center for Hospital Finance.

Eric's dissertation is titled "Essays on Markets for Health Care Services for Medicaid Adults," and focuses on supply- and demand-side effects of the Affordable Care Act's expansion of the Medicaid program to low-income adults.

Susan Christiansen, PhD candidate

SusanCSusan is a health economics student in the Department of Population, Family and Reproductive Health. She has a BA in Economics from Brigham Young University and an MA in Public Policy from Johns Hopkins University, with certificates in Health Policy and Health Disparities. Susan worked as an economic consultant for Charles River Associates for three years prior to starting graduate work. While there, she performed economic analyses for litigation and anti-trust cases primarily in the health care industry, building complex econometric models to estimate damages in pharmaceutical lawsuits or projected market share after a proposed hospital or health insurance company merger.

Susan’s research interests center around the economics of reproductive health, including efficient pricing and provision of reproductive health services. Her research at Johns Hopkins has focused on the impact of pregnancy intentions on child survival and education in Bangladesh and contraceptive pricing in Texas. She is also working on a project for USAID to build models to predict the impact of interventions on chronic conditions among maternal populations. Her dissertation will calculate the price elasticity of demand for contraceptives in Texas, and use these elasticities to estimate the impact of various policies on contraceptive use, failure rates and unintended pregnancy rates.
