I am a research assistant professor and NSF postdoctoral fellow in the
Department of
Mathematics, Statistics and Computer Science at
the University of Illinois at
Chicago. My research interests include Teichmuller theory, minimal surfaces, Kleinian groups, Higgs bundles and the geometry of character varieties.

- Domains of discontinuity for almost-Fuchsian groups. New.

Submitted. - Entropy, Minimal surfaces, and negatively curved manifolds. New.

Submitted. - Hitchin harmonic maps are immersions. New.

- Patterson-Sullivan measures and the space of negatively curved Riemannian metrics. (Joint w/ M. Lee)
#### Notes

- Harmonic maps - From representations to Higgs bundles. This is a preliminary draft of notes about harmonic maps and Higgs bundles I wrote for the workshop entitled "Higher Teichmuller-Thurston Theory" which was held in Maine during the summer of 2013.
