Dr. Su is a cancer epidemiologist experienced in environmental contamination, nutritional assessment, and survey study design. He was the PI of the ARCH study from 2016-2022, and over the past few years, he has traveled to disadvantaged communities throughout the state and met with stakeholders to identify strategies to address cancer disparities. Dr. Su is currently the Associate Dean for Academic Affairs in the Peter O’Donnell Jr. School of Public Health at UT Southwestern in Dallas. He plans to
continue working with the ARCH and to research into factors that lead to health disparities in disadvantaged communities.
Dr. Brian Koss
Assistant Professor of Biochemistry and Molecular Biology
University of Arkansas for Medical Sciences
My areas of expertise include, T-cell biology, cancer biology, proteomics, histone epigenetics, cell death mechanisms, and mouse models. Research in my lab is currently focused on developing and applying cutting-edge proteomic approaches to understand the ability of a T cell to persist in solid tumors. To translate these findings, my laboratory seeks to establish new immune monitoring methodologies and engineer CAR T-cell therapies with superior persistence in the solid tumor environment. I work with other ARCH investigators to explore the impact of environmental exposure to heavy metals on T-cell function.

Yong-Moon (“Mark”) Park MD, MS, PhD
Fay W. Boozman College of Public Health
Department of Epidemiology
My research focuses on the etiology and prevention of breast and other cancers and cardiometabolic diseases, including obesity, type 2 diabetes, hypertension, and metabolic syndrome, as well as the influence of dietary, genetic and epigenetic, and social determinants of health factors on risk and prognosis of these conditions. This work includes mechanisms by which dietary patterns and nutrients affect cardiometabolic disease and breast cancer risk.
My breast cancer research exploring the role of metabolic status and dietary patterns in breast cancer risk is based on data from the NIEHS Sister Study, a large prospective cohort of women who have a biological sister with breast cancer but, at enrollment, had no history of breast cancer themselves. I am also interested in the influence of health disparities and social determinants of health on cardiovascular complications and prognosis among breast cancer survivors, leveraging a unique combination of comprehensive administrative healthcare data sets, such as the Arkansas All-Payer Claims Database and the UAMS electronic health records system. My other ongoing collaborations include the assessment of cardiometabolic dysfunctions in cancer survivors and the general population using secondary data from the Korean National Health Insurance Service database, which covers nearly the whole Korean population.
The MammoVan regularly travels throughout Arkansas providing digital screening mammograms and breast care education.
The three-room mobile unit is outfitted with the most advanced digital mammography equipment and is staffed by a certified mammography technologist and a technical assistant.
Patients receive their test results within one to two weeks. Results also will be sent to each patient’s primary care physician. If the mammogram shows a potential abnormality, the patient will be referred for follow-up to the appropriate services.
The unit is handicap accessible, with a wheelchair lift entering directly into the mammography suite. The mammography unit also is designed to accommodate women in a standing or seated position.
