Welcome
Welcome to my page. My name is Paul Johns, and I am a PhD Candidate in Chemistry at the University of Notre Dame. My research focuses on the propagation of surface plasmon polaritons through gold nanostructures and how defects and discontinuities can disrupt or enhance this propagation. I use a pump-probe technique with a galvo-scanning mirror developed during my time in the Hartland Lab to interrogate the samples. To further understand the propagation, I also model the structures using the finite element method program COMSOL Multiphysics®. I enjoy teaching as well, and have taught in a variety of capacities: as an undergraduate and graduate TA, as Visiting Laboratory Instructor where I taught Physical Chemistry I Lab, General Chemistry II Lab, and Organic Chemistry I and II Lab, and as the primary instructor of the Physical Chemistry II course.
