Biography and academic career Marci received his B.A. in psychology at Columbia University, M.A. in psychology and philosophy at St Catherine's College, Oxford as a Rhodes Scholar, and then completed his M.D. at Harvard Medical School. He had further training in biometrics and the neuroscience of emotion through two National Institute of Health fellowships.

His early work focused on physiologic concordance or synchrony between patients and doctors as an indicator of empathy. One study, published in the Journal of Nervous and Mental Disease found a relationship between high levels of physiologic concordance and empathy in a clinical population.

Later in his career, he was inspired by the birth of his three children and the relationship between growing use of mobile media, information and communications devices and rising rates of mental illness among young people. This led him to write and publish his first book, Rewired: Protecting Your Brain in the Digital Age (Harvard University Press, 2022).
