Current Research

My research presently focuses on computational spectroscopy of ligand-coated semiconductor nanoparticles. Nanoparticles are proposed for a wide variety of applications including photovoltaics, solid-state lighting, and bio-imaging. However, the performance of such systems can depend substantially on the surface environment of the particles. By correlating structural and spectroscopic information, both experimental and computational, we seek to understand the effect of surface chemistry on the physical properties of the nanoparticles.

Original Contribution

Beyond running existing codes to calculate structural and spectroscopic properties of ligand-passivated nanoparticles, I am currently developing code to calculate Auger spectra for these systems. While Auger spectra have been calculated previously for a limited set of systems, the size and heterogeneous nature of our structures requires a new approach in which excited-state properties are evaluated in real-space rather than Fourier space.
