About Us

Our lab uses smartphone-based Ecological Momentary Assessments.

Dr. Michael Businelle's research lab is a cornerstone of the Health Promotion Research Center (HPRC), specializing in the use of mobile health technologies. The lab employs ecological momentary assessments (EMAs), passive sensor data, and just-in-time adaptive interventions (JITAI) to gain insights into the complex interplay between the environment, thoughts, feelings, and health behaviors. Driven by a multidisciplinary team with expertise in psychology, communication, and technology, the lab is devoted to developing and implementing real-time, mHealth interventions. Their diverse research initiatives encompass mobile health technology, smoking cessation, mental health, and health disparities in various populations, reflecting the lab's commitment to understanding and addressing health challenges from multiple angles​​.

Michael Businelle, PhD

Co-Director of the TSET Health Promotion Research Center, Director of the mHealth Shared Resource at the TSET Health Promotion Research Center at the OU Health Stephenson Cancer Center, Professor, Department of Family and Preventive Medicine

Michael Businelle was recruited to the University of Oklahoma Health Sciences Center in 2015 to develop and direct the OU Health Stephenson Cancer Center Mobile Health (mHealth) Shared Resource. The mHealth resource is staffed by 5.5 computer scientists/engineers and 4 additional staff members. The InsightTM platform enables researchers to rapidly create mobile applications that can use ecological momentary assessments (EMA) and sensor data (i.e., activity monitor, mobile carbon monoxide monitor, e-cigarette device) to identify environmental, cognitive, affective, physiological, and behavioral antecedents of health risk behaviors (e.g., smoking, heavy alcohol use, poor diet / inactivity / obesity, etc.) and deliver context-specific adaptive interventions in real-time. To date, the mHealth resource has supported 84 research studies (43 NIH funded, 5 studies have collected data outside the US – Cambodia, Laos, and Scotland; 5 languages [English, Spanish, Khmer, Vietnamese, and Lao]).

Since 2011, Dr. Businelle has been the PI on 20 studies that have been funded by the NIH, ACS, and internal funds and he has a strong publication record (i.e., over 185 peer reviewed publications) in the areas of smoking cessation, mental health, health disparities, and mHealth. Nineteen of his previous studies collected EMA data to identify mechanisms of health risk behaviors and 15 studies have used smartphones to intervene to improve health behaviors in real-time. His primary goal is to improve understanding of the causes of health disparities and to create and disseminate effective smartphone based just-in-time adaptive interventions (JITAIs) that reduce health disparities.

Postdoctoral Research Fellows

Headshot of Dr. Tonkin

Sarah Tonkin, PhD

Sarah Tonkin, PhD, is a Postdoctoral Research Fellow at the TSET Health Promotion Research Center at the OU Health Stephenson Cancer Center. Sarah earned her BS in Psychology from Penn State University and her PhD in Clinical Psychology from The State University of New York at Buffalo. She completed her clinical internship at the University of Texas Health Science Center at Houston. Sarah’s research seeks to identify psychological treatment mechanisms for smoking cessation and address treatment disparities by examining how these processes vary in populations that tend to benefit less from smoking interventions. To answer these questions, Sarah uses a translational approach by examining laboratory and “real-world” measurement of behavior, affect, and cognition.

Bingjing Mao, PhD

Dr. Bingjing Mao began her postdoctoral research fellowship at the HPRC in August 2022 after earning her Ph.D. in Communication Studies from the University of Miami. Dr. Mao’s research program involves the intersection between media psychology, digital technology, and cancer communication. Specifically, her research aims to understand the cognitive mechanisms through which interactions in a technology-mediated environment can impact health outcomes. Additionally, she is interested in the emotional processes behind health decision-making. As a research fellow at the HPRC, Dr. Mao can envision contributing to the multidisciplinary scholarship of digital health by working with her mentors Drs. Michael Businelle and Jordan Neil.
