Undergraduate Research


Undergraduate research is a key component of my group and an area of great pride.  Below is a list of undergraduate research projects, Honor's thesis and high school research project that I have supervised.  Most of these research projects ended with the students giving presentations either to the funding agency or at a conference.  Click on the poster link to download a reprint of the student's presentation.
