Miami University

Dr. Paul Branscum is an Associate Professor of Public Health in the Department of Kinesiology & Health at Miami University, in Oxford, OH. Dr. Branscum is a registered dietitian by initial training, earning his B.S. in Human Nutrition (2005) and M.S. in Nutrition (2008) at The Ohio State University. He then earned his Ph.D. in Health Promotion & Education from the University of Cincinnati in 2011. Dr. Branscum has published over 80 peer-reviewed journal articles, and his main research focus has been in the area of nutrition and childhood obesity prevention; specifically, predicting and changing obesogenic health behaviors among children, parents and young adults. Health behaviors he has studied includes: snacking behaviors, physical activity, sedentary behaviors, sleep, and parental monitoring behaviors centered around sugar sweetened beverage consumption and fruit and vegetable intake. Additionally, his research focuses on planning, implementing and evaluating innovative theory-based obesity prevention programs. He is also interested in the area of Health Literacy (specifically digital health literacy) and uses quantitative and qualitative methods to understand how individuals search for, and find, health related information on the Internet. Recently, his research has focused on methods to better operationalize psychosocial constructs used in theories of behavior change (i.e. perceived norms, and perceived behavioral control/self-efficacy), to be better able to evaluate them in research and in practice.

Scott Leatherdale, PhD, FAAHBScott Leatherdale, PhD, FAAHB
University of Waterloo - School of Public Health and Health Systems

Dr. Scott Leatherdale is a Professor, a CIHR-PHAC Chair in Applied Public Health Research in the School of Public Health and Health Systems, and a University Research Chair at the University of Waterloo. His work focuses on advancing a systems science approach to primary prevention activities, developing and evaluating population-level health interventions across multiple risk factor domains, and creating research infrastructure to facilitate large population studies in chronic disease prevention. His work is designed to engage numerous stakeholders at multiple-levels (regional, provincial, national) to impact the Canadian population. The core foundation for his current program of research is the COMPASS System; a prospective cohort study following 75,000+ Canadian youth to evaluate how ongoing and real-world changes to programs, policies, or built environment resources surrounding youth impact multiple health behaviours and outcomes over time. Dr. Leatherdale was the inaugural winner of the Canadian CIHR-IPPH Trailblazer Award in Population Health Solutions. To date, he has been a Principal Investigator (PI) on 38 research grants totalling more than $8.7 million ($4.3 million in current funding), has received salary awards totalling more than $1.5 million, and has published 220+ peer-reviewed journal articles (150+ first author or senior author papers), with more than 200 different co-authors.

Hsien-Chang Lin, PhD, FAAHBHsien-Chang Lin, PhD, FAAHB
Indiana University

Dr. Hsien-Chang Lin is a Professor of Health Policy at Indiana University School of Public Health at Bloomington. Before joining Indiana University, he was trained in Economics (BA and MAs), Sociology (BA), Health Policy and Pharmaceutical Health Services Research (dual PhD), and Pharmacoepidemiology and Comparative Effectiveness Research (Postdoc). His research program encompasses health services, health policy, pharmaceutical health outcomes, and health behavior research.

Guided by the socioecological model of health, Dr. Lin applies multidisciplinary perspectives and methods to bridge macro-level health policy analysis to micro-level health behavioral research. Recently, he is particularly interested in how policies may influence substance use/misuse behaviors, including e-cigarette vaping behaviors as well as physicians’ prescribing and patients’ use/misuse of prescription opioids. His work also focuses on adopting innovative methods to address complex health issues, such as using big data methods to deal with high-dimensional quantitative data in policy and genetics to study their influences on substance use/misuse behaviors. His research is supported by federal and state agencies including the National Institute on Drug Abuse and Indiana State Department of Health.

Dr. Lin is a full member of AAHB since 2014 and has been active in his service to the Academy.

He enjoys being a devoted member of the Academy, his “academic home”. He continues to encourage students and colleagues to join this marvelous organization that has many phenomenal and passionate health behavior researchers.

Mary A. Steinhardt, EdD, LPC, FAAHBMary A. Steinhardt, EdD, LPC, FAAHB
University of Texas at Austin

Dr. Mary Steinhardt is Professor of Health Behavior & Health Education in the College of Education at The University of Texas at Austin. Dr. Steinhardt also serves as the University Faculty Ombuds. She is the recipient of the first annual Dean’s Distinguished Teaching Award in the College of Education, the Texas Excellence Teaching Award presented by the Texas Exes, and the Regents Outstanding Teaching Award from the University of Texas System. She also serves as a Senior Provost Teaching Fellow and is a member of the Academy of Distinguished Teachers. Dr. Steinhardt has worked with such companies as 3M, Motorola, Dell, and Applied Materials, as well as the military at Brooke Army Medical Center and Fort Hood. In 2017, she received The Civitatis Award, the highest distinction made by the University of Texas in recognition of outstanding faculty citizenship.

Dr. Steinhardt’s research broadly examines determinants and methods for building resilience and strength when challenged with change and stressful situations. Current projects focus on biopsychosocial pathways to type 2 diabetes in racially/ethnically diverse populations and resilience-based multi-behavior interventions to reduce these disparities. For example, her grant from the National Institutes of Health (NIDDK, R01) examines behavioral and biological pathways (HPA axis activity) by which resilience resources impact type 2 diabetes health outcomes among African Americans. Her research group also examines the role of campus integration as a moderating variable in the association between resilience and mental health outcomes among underrepresented minority college students, finding that greater resilience is associated with lower anxiety for students with higher versus lower campus integration.
