Prof. Wagner received his bachelor's degree from North Carolina State University in 2002 and his PhD from the same institution in 2006. He then worked as a postdoc at Berkeley for two years, followed by a second postdoc at MIT in 2009. In 2011, he joined the physics department at Illinois.

He has pioneered the use of many-body electronic methods, in particular quantum Monte Carlo methods, to treat interacting systems of electrons in materials. His group has used these techniques to clarify the physics of strongly correlated systems such as the high temperature superconducting cuprates and vanadium dioxide. His group has developed new techniques to derive the collective physics of interacting quantum particles from these detailed calculations using data-based techniques.

Prof. Wagner is also active in software development, to enhance the availability of quantum many-body methods. He developed the QWalk package for quantum Monte Carlo, which scales these calculations to more than 1 million threads. Recently, he has been developing the pyscf/pyqmc ecosystem for many-body quantum projects.

Research Statement

I am interested in using high performance computation to simulate complex systems, and draw physical insights from those simulations. One major example of this is using quantum Monte Carlo calculations to accurately describe the wave functions of realistic models of electrons and nuclei, including the correlations that electrons have with one another. I am particularly interested in drawing conceptual information about how the electrons move in a correlated way. This research area can connect directly to experiments, since the calculations are realistic, and also connect to more coarse-grained theory, by solving for the effective physics of electronic systems.
