Biography
Zhenqiu Lin, PhD is Senior Director of Healthcare Analytics at the Yale/Yale-New Haven Hospital Center for Outcomes Research and Evaluation (CORE) and Senior Research Scientist at Yale University School of Medicine. He received his undergraduate and master degrees from Peking University, China and his PhD from the State University of New York at Stony Brook. His interests focus on developing quality of care measures to evaluate healthcare provider performance and advancing measurement sciences. He has led the development of many quality measures that cover different care settings including hospital, hospital outpatient department, ambulatory surgical center, accountable care organization, eligible clinician and group practice. Most of these measures have been endorsed by National Quality Forum and are now publicly reported by CMS. Recently, he has focused on developing innovative metrics that shed light on health disparities both within and across healthcare providers while simultaneously conducting research to evaluate the tangible impact of social risk factors like housing, income, education, transportation, food security, and limited access to resources
