Ron Hosek has worked in research, both basic and applied since his undergraduate days. This work has been directed primarily in the medical and chiropractic fields but has included projects in many other diverse areas as well. He served on the research faculty of Life University through most of the 1980s, serving as department chair from 1983 to 1986. Prior to coming to Life, he served as Research Director for the Department of Neurological Surgery at the University of Miami School of Medicine. Since leaving the Life faculty, he has been in the private practice of chiropractic and has worked as a consultant, focusing mainly on projects involving internet database and website creation. Dr. Hosek holds a PhD in Biomedical Engineering from Marquette University, a DC degree from Life and an MPH in epidemiology and biostatistics from Emory University.
Edward F. Owens, Jr.
Ed Owens has been involved in chiropractic research for more than 30 years. His background is in biomechanics with an MS in Engineering Science & Mechanics from Georgia Tech and a DC degree from Life University. He worked in the Life University research department from 1982-1999, serving on the research faculty and as editor of CRJ. He was then Research Director at Sherman College and also worked at Palmer College in biomechanics research and Northwestern Health Sciences University as Director of their Office of Data Management, an arm of the research department. Owens has over 40 publications and many conference presentations, including 3 award-winning papers. He is currently research director at TriMax Direct, a marketing firm in St. Paul where he is mastering database design and programming as well as statistical analysis.
He has worked with Ron Hosek on many projects over the years, both in research and in database software design. Together, they developed an office management system they marketed and maintained for 10 years. The system was written in an MS-DOS system but never ported to Windows or a more modern platform. They also co-developed software in the Visual BASIC/MS-SQL environment to manage patient recruitment and screening for research projects.
Emily Drake is a research scientist for the Dr. Sid E. Williams Center for Chiropractic Research at Life University. She leads a neurophysiology line of research investigating how the chiropractic adjustment influences brain function, which can provide insight into the relationship between chiropractic and neuroplasticity. She received a Bachelor of Science in biopsychology from Life University in 2016 and a Master of Science in human performance-clinical from Liberty University in 2022. She has worked with the Sid E. Williams Center for Chiropractic Research since 2016. Her research interests include understanding more about chiropractic’s impact on the brain, daily function, and overall health and well-being.

Kate Hayes has been engaging with data since her undergraduate career. She earned her Bachelor of Physics from the University of North Georgia where she focused on astronomy. Following her passion for learning, she attended Vanderbilt to enhance test methods for radiation-hardened semiconductor devices. She graduated with a master’s in electrical engineering.
After formal education, Kate served as the Tennessee Dept of Agriculture’s metrologist. She tested and enforced the state’s legal weights and measures for accuracy and traceability to National and International Standards. Her heavy use of statistics in the metrology field prompted an intentional pursuit of a data science and analytics career. The experience of data analysis utilizing Excel and Python Kate gained over the years is now benefiting the CCR. Joining the CCR team in 2021, Kate serves as the Technical Research Analyst and participates with various projects. When not crunching data, Kate enjoys mountain biking, hiking, and reading
