David Mokler received his doctorate at Michigan State University. His research in the lab of Richard Rech focused on the role of serotonin in the behavioral effects of psychedelic drugs. Their work was some of the early work to show that psychedelics such as LSD and mescaline worked through 5-HT2 receptors. His post-doctoral work was at the Medical College of Virginia with John Rosecrans. There he focused his work on the behavioral and endocrine effects of THC. He spent the rest of his career at the University of New England where he continued his work on serotonin, publishing over 60 peer reviewed papers. Recently, he has joined the team at HAVNlife as a scientific advisor. He has also joined his long time collaborator Geoffrey Bove at his CRO BoveLabs.
