Our Trainees assist researchers in finding results in the latest area of addiction research.


Michael J Wedemeyer, PhD

Department of Pharmacology

Dr. Wedemeyer is a postdoctoral researcher working under the guidance of Dr. William P Clarke and Dr. Kelly A Berg at UTHSCSA. Their research is focused on understanding how drugs interact with opioid receptors with the goal of developing pain-relieving drugs without the addictive side effects of many opioids.


  • G protein-coupled receptors (GPCRs)
  • Computational molecular modeling


Dr. Wedemeyer received his bachelor’s degree in BioMolecular Engineering from Milwaukee School of Engineering in 2015. During his final year, he led a research team of four students working on developing a novel drug delivery system to the colon. This work was published along with a follow up manuscript describing potential use of their hydrogels as artificial red blood cells. After graduation, he attended the Medical College of Wisconsin where he discovered his interest in structural biology. Dr. Wedemeyer joined the lab of Dr. Brian Volkman and investigated chemokine-receptor interactions via NMR and cell-based assays. After he attended a bootcamp for learning the Rosetta molecular modeling suite, he spent a month in the lab of Dr. Jens Meiler at Vanderbilt University to jumpstart his development of a Rosetta protocol to model chemokine-bound receptors. The capstone of his PhD work involved combining bioinformatics and in vitro experiments to investigate how the two main chemokine subfamilies selectively bind their receptors.
