Substance Use Epidemiology and Health Outcomes (SUEHO) Laboratory

Clemson students working in a group

About SUEHO

The Substance Use Epidemiology and Health Outcomes (SUEHO) Collaborative is designed to address the continuing problem of substance use in the United States with specific consideration for more rural areas. Our team works to collaboratively explore and address some of these substance use-related issues through multidisciplinary research, innovative teaching and student mentoring and collaborative engagement with impacted communities. 

Mission

Substance use negatively impacts millions of people across the United States, and nearly every community. The work we do is critically important, and part of associated works across the country. Each of us has the ability to make a positive influence in lives and communities impacted by substance use. 

Our Research

Our collaborative network includes Department of Public Health Sciences research faculty, teaching faculty, affiliated faculty across departments, graduate student researchers, and community partners working together to advance substance use research, education, harm reduction, and community engagement.

If you are interested in learning more about the research and education as part of possible graduate study, please reach out to Rachel Mayo, Ph.D.

  • About Our Team

    Our team includes:

    • Primary research faculty within the Department of Public Health Sciences who approach specific aspects of substance use and how to reduce and mitigate associated harms
    • Primary teaching faculty who provide support for this research and students through the courses they teach, and also work to bring the research into the classroom
    • Affiliated faculty from our own and other departments with whom we partner in research and teaching
    • Graduate students who are working in this space and with our partners for their research
    • Community partners without whom much of our field work and community engagement could not occur. 

    Our portfolio is similarly diverse with multiple current funded projects and pilot projects reflected in our manuscripts, publications and conference presentations. Our portfolio also includes a suite of associated courses (undergraduate, graduate, and independent study) that support our research and prepare students to be active workers and researchers in this space.   

  • Primary Research Faculty

    Wiley Jenkins Wiley Jenkins, Ph.D., MPH
    Professor and chair of the Department of Public Health Sciences at Clemson University, he spent 13 years with the Illinois Department of Public Health before moving into academia in 2007. He began exploring and working to address rural health disparities in 2009 on the topic of sexually transmitted infections, made a purposeful shift to rural cancer disparities and epidemiology in 2012, and in 2017 (through 2023) was fortunate to partner with Dr. Mai Pho and co-lead the NIH/NIDA-funded clinical trial Ending Transmission of HIV, HCV, and STDs and Overdose in Rural Communities of People who Inject Drugs (ETHIC). As part of the national Rural Opioid Initiative, this work was foundational to developing the organizational and community collaborations to successfully perform large-scale engagement among people who use drugs in rural areas. Further, it allowed exploration regarding the multiple dimensions of health we all experience, to include such factors as health care access and utilization, cancer risk and screening, and personalized and person-centered means of engagement. Jenkins is actively engaged in helping establish similar, field-based collaborations to continue to work with rural PWUD and address their contextually-specific health risks and opportunities.

  • Affiliate Researchers

    Brian WitrickBrian Witrick, Ph.D. 
    I am an Assistant Professor at Clemson University, and my research focuses on chronic disease outcomes, substance use, and health disparities. I apply spatial and quantitative epidemiological methods to investigate how substance use contributes to adverse health outcomes, particularly among individuals with cardiovascular disease. My recent work has examined the association between substance use and stroke risk among individuals with heart failure, with a focus on how community-level socioeconomic distress modifies this relationship. I am also a co-investigator on Pathways to Purpose: Recovery and Workforce Opportunities for Stimulant Use Disorder, which is investigating recovery and workforce reentry pathways for individuals with stimulant use disorders. In addition, I have contributed to research on access to mobile health clinic services for hepatitis C screening among medically underserved populations and served as a dissertation committee member for a project on mobile clinics, spatial access, and overdose management. Collectively, these experiences reflect my commitment to advancing substance use research and addressing disparities in vulnerable communities.

  • Graduate Student Researchers

    Madison BrileyMadison Edgar, M.S. 
    Madison is a Ph.D. student in the Applied Health Research and Evaluation program with a focus on substance use research, particularly its impact on maternal and child health. She is especially interested in how pregnant women often face unique barriers and disadvantages when navigating substance use and treatment, which can affect both their own well-being and that of their infants. Ms. Briley works with Dr. Rachel Mayo and Prisma Health on the Managing Abstinence in Newborns (MAiN) program, which partners with hospitals across South Carolina to improve care for infants with neonatal abstinence syndrome (NAS). As part of this effort, their team engages with mothers who are using opioids to better understand their experiences and strengthen patient-centered approaches to care. This work continues to motivate her to pursue research that drives improvements in substance use care and creates healthier futures for women and children.
