Bio Abstract

Dr. Longjian Liu is an associate professor and has worked in the Department of Epidemiology & Biostatistics, Drexel University School of Public Health since 2005. Prior to joining Drexel, Dr. Liu had extensive training, teaching and research experience in leading universities of China, the United Kingdom, Japan, and in the University of Arkansas for Medical Sciences, AR.

Dr. Liu teaches Cardiovascular Disease Epidemiology and Prevention, and Epidemiology for Public Health Practice. Dr. Liu also led the course design and taught the online course, entitled “Certificate in Epidemiology and Biostatistics Principles and Methods for Public Health in the 21st Century”. Dr. Liu coauthored the chapter of Cardiovascular Disease Epidemiology for an APHA-published text entitled Chronic Disease Epidemiology and Control (3rd Ed., 2010). Dr. Liu’s teaching philosophy is Students First!

Dr. Liu’s research has focused on epidemiology of cardiovascular disease, metabolic disorders, nutrition, aging and global health. Dr. Liu has worked for several regional, national and international studies, and has had more than 60 articles published in peer-reviewed journals. The key theories applied in Dr. Liu’s studies are the integrated ecological models, chronic care model and disease being unequally (not-randomly) distributed in population. The overarching goal of his research is to translate social and biological finings to practical application of control of disease and risk factors. Three integrated themes are included in his research activities:

(1). Built environments, diet and biomarker determinants of hypertension, heart disease, stroke and diabetes mellitus.

(2). Micronutrients, metabolic disorders, oxidative stress, lipid profile and inflammation in relation to risk of heart disease, stroke and diabetes mellitus.

(3). Global health. Dr. Liu has involved in the World Health Organization - Cardiovascular Disease and Alimentary Comparison (WHO-CARDIAC) Study, the WHO – World Health Surveys, and the Study on Global Ageing and Adult Health (SAGE). The goal of these studies is to examine health inequality and prevention of non-communicable disease cross nations.   

Dr. Liu received his medical degree in Shanxi Medical University, Taiyuan, China, master degree of science in epidemiology in the University of London School of Hygiene & Tropical Medicine, London, UK, and doctor of philosophy degree in cardiovascular disease epidemiology in the University of Hong Kong, Special Administrative Region of China, and postdoctoral Geriatrics Fellowship in the University of Arkansas for Medical Sciences, AR.

Recent Research

Heart Failure Prevention Study for African Americans: This project aims to examine association between health behavior changes and heart failure risk reduction among African American patients with heart failure stages A, B and C. Role: PI.

Nutrition, Renal Dysfunction and Heart Failure: The study aims to investigate malnutrition and chronic renal function decline in relation to heart failure among minority and white populations. Role: PI.

Participatory Statewide Evaluation of the Pennsylvania Cancer Education Network: This project aims to evaluate and develop the Pennsylvania Cancer Education Network for the implementation of a public education program. Role: Co-I.

Mind-Body-Spirit-Health Collaborative - Advancing System Improvements to Support Targets for Healthy People, Role: Co-I.

Diet, Biomarkers and Cardiometabolic Disorders: This study uses existing data from nationally representative cross-sectional and longitudinal studies to examine risk factors and cardiovascular disease at regional, national and international levels. Given the characters of the large-scale and representative sample sizes, several hypothesis-driven projects are currently being conducted as my MPH and PhD students’ dissertation projects.

Healthcare system, Public Health Biology and Global Health: This project uses data from the World Health Organization Surveys to examine built environment, healthcare support and population health cross multiple culture, race/ethnicity and nations.
