Leon Balents    

University of California Santa Barbara

Dr Leon Balents is a theoretical physicist working on quantum states of matterHe received a bachelor's degree from MIT in Physics and Mathematics in 1989, and PhD from Harvard in 1994.  He was a postdoc at the then ITP, and then spent time at Bell Laboratories as a member of technical staff.  In 1999 he joined the faculty of the physics department at UCSB, and in 2008 was appointed as a Permanent Member at the KITP.  

Dr. Balents’ research group studies how many quantum particles interact with one another to collectively produce "emergent" phenomena.  While some of these assemblies of particles are familiar (for example every rock is one), some may do remarkable things.  (Even some of those rocks may be remarkable!).  The group seeks to find the remarkable examples, understand how to study and use them in the laboratory, and how new and beautiful mathematical structures describe them.

Collin Broholm  

Johns Hopkins University

Collin Leslie Broholm is the Gerhard H. Dieke Professor in the Department of Physics and Astronomy at the Johns Hopkins University. He earned his PhD from the University of Copenhagen in 1988, was a post-doc at AT&T Bell Laboratories from 1988–1990, and joined Johns Hopkins in 1990.

An experimental condensed matter physicist, Dr. Broholm is interested in anomalous forms of magnetism, superconductivity, and their interplay. Of particular interest are crystalline materials where quantum effects are enhanced on account of competing interactions (frustration) or low dimensionality. The main experimental tool is neutron scattering and Dr. Broholm has a long-standing involvement in development of the corresponding instrumentation. He has built two spectrometers at the NIST Center for Neutron Research and has served on various committees overseeing instrumentation development at National facilities for Neutron Scattering.

Dr. Broholm received the Presidential Faculty Fellowship in 1994, became a fellow of the American Physical Society in 2004, and received the Sustained Research Award of the Neutron Scattering Society of America in 2010. Dr. Broholm is the director of the Johns Hopkins Institute for Quantum Matter and is also affiliated as a joint faculty with Oak Ridge National Laboratory. In 2014 Broholm was selected as a Moore Experimental Investigator in Quantum Materials.


Alannah Hallas  

Stewart Blusson Quantum Matter Institute

Alannah Hallas is an Assistant Professor in the Department of Physics and Astronomy at UBC and has joined SBQMI to head the Quantum Materials Design Lab. Before coming to UBC, Alannah completed her PhD in physics as a Vanier Scholar at McMaster University and was the Smalley Postdoctoral Fellow at Rice University. Having worked in both physics and chemistry departments, Alannah is passionate about taking an interdisciplinary approach to the study of quantum materials.


Roser Valenti   

Goethe-Universität Frankfurt am Main

Roser Valenti is professor of physics at the Goethe University Frankfurt. She received her Ph.D. degree in theoretical physics at the University of Barcelona. Before joining Frankfurt, she was postdoctoral Fulbright fellow at the University of Florida at Gainesville, Habilitation researcher at the University of Dortmund and Heisenberg fellow at the University of Saarland, Germany. From 2009 to 2012 she was vice-president of the Goethe University Frankfurt and since 2016 she is an American Physical Society Fellow. Her field of research is the microscopic modeling of correlated materials such as unconventional superconductors, frustrated magnets and systems with topologically non-trivial states via a combination of first-principles- based methods and many-body numerical techniques.  (


Lucile Savary

CNRS, École Normale Supérieure de Lyon

Lucile Savary is a permanent CNRS researcher in condensed matter theory at the ENS Lyon.  She completed her PhD with Prof. Leon Balents, at UCSB, and  was a Gordon and Betty Moore postdoctoral fellow at MIT. Her research focuses on exotic phenomena in real systems, with an emphasis on frustrated magnetism. It includes quantum spin liquids, and in particular quantum spin ice, order-by-disorder, quantum criticality, the theory of RIXS, spin-orbital systems, the anomalous Hall effect, and non-centrosymmetric superconductors.


Markus Grueninger

Professor of Physics at the University of Cologne, Germany

Markus Grueninger studied physics at the University of Karlsruhe, Germany. He received his Ph.D. from the University of Groningen, in The Netherlands (1999). From 1999-2004, he studied as a postdoctoral at the University of Cologne, Germany. Following postdoctoral training, he joined RWTH Aachen University, Germany as a Professor of Physics until 2007. Since 2007, Grueninger has served as a Professor of Physics at the University of Cologne, Germany. His research focuses on spectroscopy from THz to x-ray range, electronic correlations quantum magnetism, and strong spin-orbit coupling.  


Lynne Vincent
Assistant Professor of Management
Syracuse University

Lynne Vincent holds an M.S. and Ph.D. in Organizational Behavior from Cornell University, School of Industrial and Labor Relations. She is currently an assistant professor at the Whitman School of Management at Syracuse University. Before joining Syracuse University, she was a postdoc at the Owen Graduate School of Management at Vanderbilt University. Her research focuses on the moral and social implications of creativity for individuals, groups, and organizations. She teaches undergraduate courses on management and organizational behavior at Syracuse University.


Tyrel M. McQueen
Director, PARADIM Bulk Materials Synthesis and Discovery Facility

Department of Materials Science and Engineering
The Johns Hopkins University


Tyrel M. McQueen, is PARADIM facility director and associate professor in the Johns Hopkins departments of Chemistry, Materials Science and Engineering, and Physics and Astronomy. PARADIM—Platform for the Accelerated Realization, Analysis and Discovery of Interface Materials—is one of the first awards under the NSF’s new Materials Innovation Platform program. Johns Hopkins, Cornell, Princeton, and Clark Atlanta universities form a team of institutions that the agency chose for a $25 million program over five years. The facility will join the Hopkins Extreme Materials Institute, the Institute for Quantum Matter, and the Institute for Nanobiotechnology in bolstering Johns Hopkins’ status as a national leader in materials research.
