Daniel R. Marlow

Interview with Daniel R. Marlow, Evans Crawford Class of 1911 Professor of Physics, at Princeton University. Marlow recounts his childhood in Ontario and his father’s military appointment which brought his family to the United States when he was fourteen. He describes his undergraduate experience at Carnegie Mellon and the considerations that compelled him to remain for his graduate work in physics. Marlow describes his thesis research under the direction of Peter Barnes and his research visits to Los Alamos, Brookhaven, and JLab, and he surveys the theoretical advances that were relevant to his experimental work. He explains his decision to stay at CMU as a postdoctoral researcher and as an assistant professor, and he describes his interests which straddled the boundary between particle physics and nuclear physics. Marlow describes the opportunities leading to his faculty appointment at Princeton by way of the research in k+ and pi+nu nu-bar experiments at CERN. He discusses his involvement in planning for the SSC, and how the Gem collaboration was designed to find the Higgs and supersymmetry before the LHC. Marlow discusses the e787 experiment and the lesson gained that rare kaon decay experiments are more difficult than they appear at first glance. Marlow describes the origins of the Belle project in Japan at KEK and its relationship to BaBar, and he explains how finding the Higgs was the capstone to the Standard Model. He surveys the current state of play in experimental particle physics and why he encourages students to follow their interests without overly analyzing future trends in the field. At the end of the interview, Marlow describes his current interest in studying displaced vertices and long-lived particle searches, and he muses that toward the end of his career, he wants to become more of a “graduate student” so that he can focus more exclusively on the physics that is most compelling to him.
