Off the court, as a biology major she gravitated toward hormones and neurotransmitters. She grew fascinated with the neurobiology of how and why drugs such as cocaine and opioids are addictive, as she learned about the effects of ecstasy on the serotonin system. “I thought drugs were so cool because they hijack the brain,” she said. “Drugs essentially take the normal systems we have in our body and drive them in a way that makes you want to take drugs again.”

After pursuing graduate work in neuroscience, in 2017 Calipari set up her lab at Vanderbilt to explore how addiction is connected to the ways the brain learns and makes decisions. “Deciding what to do and what not to do is really fundamental to everything we do,” Calipari said. “You put your hand on a hot stove, you learn really quickly not to do that again.” Addiction can diminish a person’s ability to learn that drug use is hurting them, and also their ability to learn anything at all.
