Research Interests:
  • Bryan Clark works in the field of computational condensed matter with a focus on strongly correlated systems and many-body physics. Our physics interests are broad and we use a wide range of methods including tensor networks and quantum Monte Carlo. He also interest in the areas of quantum computation and quantum information. Bryan Clark is a condensed matter theorist who specializes in the use and development of computational simulations and models to study the complexity of behaviors and interactions within many body and strongly correlated systems. In this work, Clark fully exploits today’s powerful supercomputing capabilities and he has written a wide range of highly efficient and massively parallel numerical codes, while developing novel numerical methods that improve the accuracy, parallelizability and efficiency of computing properties of many body systems. Clark was selected for an inaugural Blue Waters Professorship, which confers a significant commitment of Blue Waters computing resources, up to 240,000 node hours per year.
