Interview with David Sokoloff, Professor Emeritus of Physics at the University of Oregon. Sokoloff discusses his focus on improving physics education at the collegiate level, and the programs and methods he has implemented to ensure that the state of physics education, both domestically and internationally, continues to advance. He discusses the workshops he has organized around the world for the development of Active Learning in Optics and Photonics (ALOP). These workshops also involve Interactive Lecture Demonstrations (ILDs), which Sokoloff has utilized throughout his career as a physics educator. He also reflects on creating Home-Adapted ILDs during COVID so that students could continue learning about these concepts during the pandemic. Sokoloff talks about how he has grappled with active throughout the pandemic, when so many aspects of education have been forced online. He discusses the challenges of replicating live learning situations through online platforms. Sokoloff then looks back on his time at MIT and his engagement with local and national politics during the 1960s and 1970s, particularly with the Teacher Corps. He returns to his discussions of Active Learning workshops and his multi-year collaboration with Priscilla Laws and Ron Thornton. Towards the end of the interview, Sokoloff remarks upon his experiences as a rep to the U.S. Liaison Committee for the International Union of Pure and Applied Physics, a rep to the International Commission on Physics Education, and a recipient of the Oersted Medal. Sokoloff rounds out the conversation discussing the importance of active learning in physics education, as well as how vital it is that students are given the space and opportunity to question ideas, make mistakes, and speak up for themselves. 

Interview with Piero Pianetta, Research Professor in the Photon Science Department, joint with Electrical Engineering, at Stanford. He recounts his family’s Italian heritage, and his upbringing in Italy and then in California. He explains his interest in pursuing physics as an undergraduate at Santa Clara University, and his graduate work at Stanford where he worked on monochromator experiments and contributed to the SPEAR collaboration at SLAC. Pianetta discusses his scientific interests converging on surface science and the influence of Seb Doniach on his research. He describes his postgraduate work at HP where he focused on laser annealing and subsequently SSRL to conduct research on device technology and photoemission techniques. Pianetta explains how SSRL became integrated in SLAC and how he became administratively housed in the Photon Science department, and how this development is illustrative of the way SLAC has diversified its research and redefined its relationship with the Department of Energy. He describes his most recent responsibilities as chair of the photon science group at SLAC and his current work chairing the laboratory promotions committee. At the end of the interview, Pianetta reflects on the long-term impact of remote work for SLAC generally and he conveys optimism on improving SSRL’s long-term capabilities.

Interview with Lene Hau, Mallinckrodt Professor of Physics and Applied Physics at Harvard. Hau recounts her childhood in Denmark and her early interests in science, and she describes her education at the University of Aarhus. She describes her studies in math and physics and her determination to build something meaningful for experimentation. Hau describes her interest in using lasers to cool down atoms during her postdoctoral work at Harvard and at the Rowland Institute, and she describes the opportunities that led to her full-time work at Rowland. She describes her collaboration with Jene Golovchenko and the impact of the discovery of Bose-Einstein condensation in 1995. Hau details the experiments that initially slowed down and then ultimately stop light in a Bose-Einstein condensate. She explains her decision to join the Harvard faculty and she surveys some of the practical applications of her research. Hau describes her research in nanoscale systems and her interest in applying her research to create more energy efficient systems with the explicit goal of addressing climate change. She describes some of the difficulties and systemic biases that women have to deal with in the sciences, particularly when they achieve prominence. At the end of the interview, Hau explains her interest to promote diversity in physics and particularly to encourage students who are the first in their generation to go to college.
