Dr. Markus is interested in the intersection of law and health care, and her grasp of health care financing and health system reform have enriched her work in the areas of health rationing, comparative health care systems, and national and international public health. In Fall 2017, she was awarded a project by the Robert Wood Johnson Foundation under its “Research in Transforming Health and Health Care Systems” program, which seeks to build the evidence base on the potential effects of policies or policy changes intended to transform health. The goal of the project is to inform the policy debate on the implications for states, health centers and patients of potential changes to the Medicaid program at both the federal and state level. In December 2017, she also became the recipient of the 2017 GW Cancer Center Catchment Area Impact Grant. Under this award, she will conduct an analysis of disparities in cancer screening behaviors in the DC region by insurance status, with a special emphasis on Medicaid. In January 2016, in collaboration with Children's National Health System, she began a three-year, PCORI-funded project, which uses mixed methods and includes a comparative effectiveness analysis of two treatment options for children with a diagnosis of urea cycle disorder. In the Summer of 2016, Dr. Markus joined the Geiger-Gibson Program in Community Health Policy, which has as its core mission to eliminate medical underservice and disparities in population health and health care and improve health and health care for all persons. Her broad and interdisciplinary training in law, public policy, and health policy, and 25 years of local, state, federal and international experience have allowed her to study private and public health insurance and public programs, such as Medicaid/CHIP, health centers, and maternal and child health services, as well as health reform in the U.S. and abroad. In general, her current research focuses on the promotion of children and women's health and the policies that support this goal. Many of her pediatric research studies have focused on young children’s access to clinically recommended preventive and developmental services and more recently on prevention and management of chronic diseases, including pediatric HIV/AIDS, childhood asthma and urea cycle disorder (UCD). Dr. Markus recently completed as PI a multi-year, multi-site translational and implementation research project (called CHAMPS short for Community Healthcare for Asthma Management and Prevention of Symptoms), which examined system changes needed to successfully adopt evidence-based childhood asthma management interventions in Community Health Centers (CHCs). At the same time, she conducted quick turnaround analyses commissioned by the Howard County Health Department (one in conjunction with the Local Children’s Board), either as a consultant or as a faculty member of the George Washington University School of Public Health. Much of her research on maternal health is about Medicaid coverage of pregnant women and birth outcomes, such as infant mortality and preterm birth, and work accommodations for nursing mothers who are returning to their job after the birth of their baby.
