John F. Barry is an experimental physicist currently at MIT Lincoln Laboratory. He received his Ph.D. from Yale University in the group of Dave DeMille, where he worked to demonstrate the first laser cooling, slowing, and trapping of a diatomic molecule. As a postdoctoral fellow in the Walsworth group at Harvard, John led a team that employed nitrogen-vacancy centers to magnetically detect single-neuron action potentials. He is now a technical staff member at MIT Lincoln Laboratory, where he is developing new quantum-based sensors for neuroscience, biomedical, and other precision-sensing applications.
