Post-doctoral Research Scholar Spotlight

Zacariah Shannon, D.C., M.S. spent 2¾ years as a post-doctoral research scholar at the Palmer Center for Chiropractic Research under the mentorship of Drs. Robert Vining and Cynthia Long. He was supported by an NIH Administrative Supplement from September 1, 2018-August 31, 2020 under the VERDICT grant (Veterans Response to Dosage in Chiropractic Therapy; UG3/UH3AT009761).

His primary work was working with the team to develop a decision aid for VERDICT and training study clinicians, resulting in four publications. He also had the opportunity to conduct a qualitative research project under the mentorship of Dr. Stacie Salsbury that resulted in one publication. He is now a full-time graduate student working on a Ph.D. in Epidemiology at the University of Iowa in Iowa City, Iowa.
