Professional Career

• 2010-present, Postdoctoral Research Associate, Los Alamos National Laboratory
• 2007-2010, Adjunct Faculty, Neumont University, Salt Lake City, Utah

Education

• 2010: Ph.D. Physics, University of Utah, Salt Lake City, Utah
• 2006: M.S. Physics, University of Utah, Salt Lake City, Utah
• 2004: B.A. Physics, University of Utah, Salt Lake City, Utah

Previous Research

• My previous research experience was in the area of Near-Field Optics. Specifically, I worked on increasing image contrast in near-field microscopy and developing a 3D tomographical imaging technique.  I have also studied nano-scale energy transfer between single carbon nanotubes and single quantum dots.

Current Research

• My current research involves mapping the near-fields of plasmonic nanostructures for applications in new classes of light-emitting diodes (LEDs).  This is done using a custom built near-field scanning optical microscope.  I also investigate optical properties of single “giant” quantum dots using this setup.

Awards

• 2008-2009: Graduate Research Fellowship, University of Utah
• 2003-2004: Physics Departmental Scholarship, University of Utah
• 1997-2003: Honors at Entrance Scholarship, University of Utah
