Biography

I received my B.A. in Chemistry from Kenyon College in 2004.  After a brief foray into industry, I entered graduate school and earned a Ph.D. in Chemistry from the University of Chicago.  This work was performed under the guidance of Steven J. Sibener, and focused primarily on the use of helium atom scattering to characterize the structure and vibrational dynamics of thin organic films.  I started as a Postdoctoral Research Associate with S. Alex Kandel at the University of Notre Dame in 2014, where I investigated the self-organization of small organic and organometallic molecules at the vacuum-solid interface using scanning tunneling microscopy.  I joined Clarkson University as an Assistant Professor in 2018.  My research group conducts research to identify the impact of chemical structure, growth environment, and molecule-substrate interactions on the formation of supramolecular structures at the vacuum-solid interface.

Research Interests
  • Growth of two-dimensional materials on solid interfaces
  • Growth of 2D materials in near-equilibrium and far-from-equilibrium conditions
  • Characterization of heterogeneous surfaces through scanning probe microscopy

Current Research

My research group uses physical chemistry and surface science methodologies to study the spontaneous organization of molecules at the gas/solid and liquid/solid interfaces under non-equilibrium growth conditions.  The goals of this research program is to discover the fundamental principles governing the self-organization of molecules at solid interfaces and to develop exploitable techniques for producing supramolecular structures that are not accessible through traditional self-assembly strategies.
