Monika Schleier-Smith, associate professor of physics at Stanford University, studies quantum mechanics, the theory that explains the nature of the itty bitty parts of our universe: atoms, photons, and individual particles. It's the science responsible for innovations in computers, telecommunications, and medicine. Schleier-Smith was recently awarded a 2020 MacArthur Fellowship for her work in the field. It's research that often starts in a lab and as Schleier-Smith describes, requires both troubleshooting and optimism.
