Theoretical Investigations of Semiconductor Nanostructures

Recently, I began work at SAS Institute Inc. in the high-performance analytics department. Because of that move, I have gone from a physicst who does programing on the side to a programmer who does physics on the side. I am still continuing my resarch outside of my office hours, and intend to continue my existing collaborations. Additional collaborations are also of continuing interest, so please let me know if you need something calculated!

I was previously a postdoctoral researcher at the University of Oklahoma in the Center for Semiconductor Physics in Nanostructures. Together with Professors Mullen, Murphy, and Santos, I examined spin and charge properties of electrons in InSb quantum well structures. Professor Mullen and I also worked with groups in the Departments of Physics and Chemistry at the University of Arkansas on nanocrystal properties. For my doctoral work at the University of Iowa, I studied electron and hole spin properties and g-tensors in quantum dots (specifically, InAs/GaAs and InGaAs/GaAs quantum dots).

I perform my calculations on a desktop PC using a variety of codes including nextnano and a number of programs which I developed. I am working on codes to leverage the power of the Sooner supercomputer in order to perform larger, more detailed calculations. In my dissertation work, I used a cluster of Mac or Linux computers using a strain-dependent k-dot-p theory which was developed by Bahder and implemented numerically by Craig Pryor.

More recently, I have gained a background in general purpose graphical processing unit (GPGPU) high-performance computing using NVidia's CUDA development environment. To that end, I have become a registered NVidia CUDA developer. Given the speed and low power per flop of GPUS, I will definitely be using this knowledge in my future numerical physics work.
