Principal Investigator

Michael Businelle, PhD

Co-Director of the Oklahoma Tobacco Research Center, Director of the mHealth Shared Resource at the Oklahoma Tobacco Research Center at the Stephenson Cancer Center, Associate 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 Stephenson Cancer Center Mobile Health (mHealth) Shared Resource. The mHealth resource is staffed by 4 programmers, a program manager, and a research technician. The InsightTM platform enables researchers to rapidly create mobile applications that can utilize 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 cancer risk behaviors (e.g., smoking, heavy alcohol use, poor diet / inactivity / obesity, etc.) and deliver context-specific adaptive interventions in real-time. The mHealth resource currently supports over 30 studies (15 NIH funded, 2 studies collected data outside the US – Cambodia, and Scotland).

Since 2011, Dr. Businelle has been the PI on 11 intervention studies that have been funded by the NIH, ACS, and internal funds and he has a strong publication record (i.e., over 115 peer reviewed publications) in the areas of smoking cessation, health disparities, and mHealth. Ten of these studies include collection of EMA data to identify mechanisms of health risk behaviors in socioeconomically disadvantaged samples. This information has been used to develop novel interventions that automatically tailor treatment content based upon an individual’s current symptoms/needs. In upcoming studies, Dr. Businelle plans to integrate real-time wearable sensor data (e.g., smoking, eating, drinking gestures) to inform intervention algorithms.

Postdoctoral Research Fellows

Emily Hébert, DrPH

Emily T. Hébert, DrPH is a postdoctoral research fellow at the Oklahoma Tobacco Research Center at the Stephenson Cancer Center. Emily earned her DrPH in Health Promotion and Behavioral Sciences from the University of Texas School of Public Health. Her dissertation focused on the use of ecological momentary assessment to measure real-time tobacco marketing and message exposure among young adults. Her current research interests include the use of technology for health promotion, tobacco prevention and cessation, ecological momentary assessment, and the role of social media in tobacco marketing and health communication.

Karen Ra, PhD

Chaelin Karen Ra, PhD is a postdoctoral research fellow at the Oklahoma Tobacco Research Center at the Stephenson Cancer Center. Karen earned her PhD in Health Behavior Research at the Keck School of Medicine of the University of Southern California.

In addition to his clinical work, Chris has helped college and professional athletes, business leaders, and performing artists optimize performance through stress management and enhancing cognitive focus. While completing his Master of Arts in Marriage and Family Therapy, Chris’ research agenda included examining psychological distress in cancer caregiving dyads.

Joseph J.C. Waring

Research Program Coordinator 

Joseph joined the Oklahoma Tobacco Research Center in the summer of 2017 after receiving a Bachelor of Public Health from the University of Kentucky. Originally from Long Island, NY, Joe's interest in smoking cessation developed while he was volunteering in a kidney transplantation center in New York City. His research interests include smoking cessation interventions among those waiting for organ transplants and interventions using mobile technology. 

Tanushri Bhushan

Research Assistant

Tanushri Bhushan joined Oklahoma Tobacco Research Center in the spring of 2019 as a research assistant after receiving a Master of Public Health (MPH) degree in epidemiology from the University of North Texas Health Science Center (UNTHSC). Tanushri has worked on multiple research projects at UNTHSC focused on behavior modifications to increase self-efficacy and physical activity to decrease stress among graduate students. Also researched the role of EDNRB for early prediction of hypoxia in patients with Sickle cell anemia (SCA). Her current research interests include behavior treatments targeting impulsivity and decision- making capacity using mobile-based technology among chronic smokers and technology-based health promotion.


LaQuita McDade

Research Technician

LaQuita McDade joined Oklahoma Tobacco Research Center in summer 2019. She received her Bachelors of Arts in Psychology from the University of Texas at Dallas (UTD) where she completed undergraduate research at the UTD Center for Brain Health. Previous research focus was on the physiological effects of anorexia nervosa and its co-morbidities. Her current research interest include the behavioral and physiological determinants of disease including smoking related illnesses and obesity. 


Audrey Montgomery

Research Technician

Audrey Montgomery joined the Oklahoma Tobacco Research Center in January 2020 as a research technician. She previously worked as a licensed professional counseling candidate after receiving her Master of Education in Professional Counseling from the University of Oklahoma. Audrey completed her undergraduate research experience at the University of Oklahoma’s Center for Applied Social Research (CASR). She worked on multiple research projects focused on the relationship between attitudes in ideological Internet discussions and emotion and communication strategies.
