Summary

Although I'm trained as a physicist, my research experience has focused on developing code for high performance computing. I've taken my experience developing for GPUs and FPGAs and applied this to develop machine learning techniques for the past couple of years. My research interests include continuing to develop machine learning techniques to tackle challenges in new data sets.
