Alex Kwan

Neuroscientist whose research focuses on the neurobiology of antidepressants, using sophisticated optical imaging methods to study how drugs such as ketamine and psilocybin modify brain circuitry. His lab develops optical imaging techniques to visualize neural structure and activity dynamics in awake mice.
