Dr. Chen is a health economist and health services researcher. She is the founder and the director of the Hospital And Public health interdisciPlinarY research (HAPPY) Lab. The mission of the lab is to improve multi-sector health care coordination for people with multiple chronic conditions.
Dr. Chen is leading the projects to estimate the impact of public health-integrated health care on health care access (R21MH106813, PI) and identify effective care coordination practices between health care and communities for minority patients with mental illness (R01MD011523, PI) and the aging population with ADRD (R01AG062315, PI). Her research suggested that community collaboration and the Accountable Care Organization that using team-based approaches and financial incentives to promote care coordination have the potential to improve health care quality and reduce disparities.
She is also among the first researchers to estimate the impact of the Affordable Care Act on health care disparities and apply economic decomposition methods to health disparity research to better isolate and quantify the importance of selected factors in explaining the racial and ethnic disparities in health care. She has published over 100 publications to evaluate health care access (e.g., access to primary care) and utilization (e.g., preventive care, mental health care, etc.) among vulnerable populations.
Dr. Chen has 17 years of research experience working with large secondary data sets and claims data and developing, refining, and applying analytical methods. She has been working closely with local health departments, hospitals, and community partners to design, develop and evaluate community interventions.
