Research Interests

    I am generally interested in the use of ultracold atomic gases to study many-body phenomena.

    I am currently building an experimental apparatus to study fermionic atoms confined in an optical lattice potential. This system provides an exciting opportunity for studies of strongly-correlated fermions in a highly adaptable and precisely controllable environment. The hope is that this research will provide some insight into fundamental many-body problems of interest in condensed matter physics.

    If this research interests you, I encourage you to inquire about joining my group. I am currently looking for motivated graduate students and a post-doctoral research associate to take part in this project.
