Alexxai Kravitz is associate professor of psychiatry at Washington University in St. Louis, where he leads a team of researchers that focuses on understanding how the brain mediates feeding and obesity in mice. In addition to a passion for understanding feeding, his lab has a strong interest in developing open-source hardware devices to study rodent behavior, and in adopting open-science practices for neuroscience research.
