In the second Nova Interview, Nova Fellow Alan Logan speaks with Dr. Christopher A. Lowry about the intersections of gut microbiome, nature, and mental health. For nearly twenty years, Dr. Lowry has been at the forefront of research connecting the microbiome to mental health, including publishing a provocative article titled “Can we vaccinate against depression?” In this interview, Dr. Lowry updates Logan on the field of integrative psychology and reflects on the early influences that shaped his career and work in microbiome sciences.
