She is a health services researcher whose work integrates health economics, epidemiology, and advanced quantitative methods to evaluate healthcare delivery, quality, outcomes, and value. Her research focuses on understanding how evolving healthcare delivery models and health policies influence patient outcomes, healthcare utilization, quality measurement, and affordability. Dr. Tian leverages large-scale healthcare databases, including administrative claims and electronic health records, to generate real-world evidence that informs healthcare policy and clinical practice. Her methodological expertise includes causal inference, quasi-experimental study designs, and advanced statistical methods for observational research. She also designs and evaluates pragmatic clinical trials and implementation studies to assess the effectiveness, implementation, and economic value of healthcare interventions. Through rigorous study designs and interdisciplinary collaborations, her work aims to improve healthcare delivery and advance high-value, patient-centered care. Before joining UT Southwestern, Dr. Tian was a faculty member in the Department of Surgery at Northwestern University's Feinberg School of Medicine. She earned her PhD in Health Services Research, with a concentration in health economics, and an MS in Statistics from Texas A&M University, as well as an MPH in Epidemiology from Emory University. Dr. Tian serves as a Principal Investigator of an R01 research grant funded by the Agency for Healthcare Research and Quality (AHRQ), examining the outcomes and affordability of observation status among pediatric patients. She also serves as a Co-Investigator on federally funded studies evaluating healthcare interventions, including initiatives to improve cardiovascular care and preventive services in community-based settings, such as workplace health centers. Her research spans healthcare policy evaluation, health economics, outcomes research, and implementation science, with applications across diverse patient populations and clinical settings. Drawing on her expertise in quantitative methods, economic evaluation, and real-world healthcare data, Dr. Tian collaborates with multidisciplinary research teams to address important questions in healthcare delivery and population health. She is also committed to mentoring students, clinical fellows, and early-career investigators in rigorous health services research.
