Research Interests:

  • Theoretical Condensed Matter Physics
  • Theoretical Atomic, Molecular and Optical Physics


Ph.D. 2000, Brown University

Current Research:

My research focuses on theoretical condensed matter and atomic, molecular and optical physics, in particular quantum many-body systems, including properties of electronic correlated materials and cold atom systems. Current and recent projects include investigation of the electronic properties of grapheme, quantum phases of cold atom mixtures, dipolar fermions, and gauge fields on optical lattices.
