ML4Q&A continues featuring theoretical physicists in ML4Q. In the second episode, Chris Dickel is talking to David Gross, professor in Cologne and vice spokesperson of the ML4Q cluster. David's research interests lie on the application of rigorous mathematical methods to problems in quantum information theory and many-body theory. We talk about his career path, advising student projects in theoretical physics, teaching quantum mechanics and the Google event he was probably never invited to.
