Stephon Alexander is a theoretical physicist, musician, and author whose work is at the interface between cosmology, particle physics, and quantum gravity. He works on the connection between the smallest and largest entities in the universe pushing Einstein’s theory of curved space-time to extremes, beyond the big bang with sub atomic phenomena.
Alexander is a Professor of Physics at Brown University, and the President of the National Society of Black Physicists. He had previous appointments at Stanford University, Imperial College, Penn State, Dartmouth College and Haverford College. Alexander is a specialist in the field of string theory and cosmology, where the physics of superstrings are applied to address longstanding questions in cosmology. In 2001, he co-invented the model of inflation based on higher dimensional hypersurfaces in string theory called D-Branes. In such models the early universe emerged from the destruction of a higher dimensional D-brane which ignites a period of rapid expansion of space often referred to as cosmic inflation.
In his critically acclaimed book, The Jazz of Physics, Alexander revisits the ancient interconnection between music and the evolution of astrophysics and the laws of motion. He explores new ways music, in particular jazz music, mirrors modern physics, such as quantum mechanics, general relativity, and the physics of the early universe. He also discusses ways that innovations in physics have been and can be inspired from "improvisational logic" exemplified in Jazz performance and practice. Alexander is also a professional touring jazz musician.

Professor Philip Phillips received his bachelor's degree from Walla Walla College in 1979, and his Ph.D. from
the University of Washington in 1982. After a Miller Fellowship at Berkeley, he joined the faculty at Massachusetts Institute of Technology (1984-1993). Professor Phillips came to the University of Illinois in 1993.
Professor Phillips is a theoretical condensed matter physicist who has an international reputation for his work on transport in disordered and strongly correlated low-dimensional systems. He is the inventor of various models for Bose metals, Mottness, and the random dimer model, which exhibits extended states in one dimension, thereby representing an exception to the localization theorem of Anderson's.
His research focuses sharply on explaining current experimental observations that challenge the standard paradigms of electron transport and magnetism in solid state physics. Departures from paradigms tell us that there is much to learn. Such departures are expected to occur in the presence of strong-electron interactions, disorder, and in the vicinity of zero-temperature quantum critical points. The common question posed by experiments that probe such physics is quite general. Simply, how do strong Coulomb interactions and disorder conspire to mediate zero-temperature states of matter? It is precisely the strongly interacting electron problem or any strongly coupled problem for that matter, such as quark confinement, that represents one of the yet-unconquered frontiers in physics. Understanding the physics of strong coupling is Phillips' primary focus.
Xiaoliang Qi is a professor of physics at Stanford University. He received his PhD in 2007 from Tsinghua University, and did postdoctoral research in Stanford University and UC Santa Barbara before joining the faculty of Stanford.

His current research focuses on the relation between quantum entanglement, quantum chaos and quantum gravity.

Black students are being excluded from the explosive growth in physics degrees through both hidden and open barriers. (Over the past 10 years, less than 4% of physics bachelor’s degrees have been awarded to African Americans, according to AIP statistics.) The larger physics community has a significant opportunity to increase the participation of persons of the African diaspora in the discipline by lowering barriers for interactions with communities within Historically Black Colleges and Universities (HBCU), Minority Serving Institutions (MSI), and Predominantly Black Institutions (PBI). In this second joint physics society webinar (view the previous webinar), panelists will highlight examples of successful partnerships that have a record of involving the 21 HBCU, 23 PBI, and four HBCU-PhD US institutions in creating effective bridges and taking a holistic view of building a unified physics community.
As physicists interested in the advancement of the discipline we must address systemic barriers in academia that have led to a gross underrepresentation of minorities, particularly Black Americans, in our field. This webinar features a panel of physicists who have been actively involved with increasing diversity in physics and improving its culture. The panel discusses why everyone from students to teachers to professors to administrators has an important role in building a diverse next generation of physicists. The panel shares ideas and concrete actions on what each of these groups can do to work toward this goal.
