The Department of Pharmacology at The University of Arizona is comprised of faculty, fellows, students, and technical staff working together to understand how chemicals influence human disease. Some chemicals and drugs are used to treat human diseases while others are known to cause human diseases. Dr. John Streicher earned his PhD from UCLA in 2009, in the lab of Dr. Yibin Wang, where he studied the signal transduction cascades linking heart stress to heart failure. He then went on to a postdoctoral fellowship with Dr. Laura Bohn at Scripps-Florida, where he studied biased signaling at the opioid receptors. In 2012, he joined the faculty at the University of New England, where he combined the threads of his training into a research program focused on the signal transduction cascades of the opioid, cannabinoid, and other brain-relevant receptors, mostly in the context of pain. He joined the faculty of the University of Arizona in 2015, where he continues his work today.
