My research primarily consists of using analytical, asymptotic, and numerical tools to investigate qualitative features of nonlinear dispersive wave phenomena, including dispersive shock waves and solitary waves. My current work is investigating these structures in the context of both shallow water and magnetic surface spin waves. For more information regarding current and published work, please see the manuscripts listed below. Feel free to contact me if you have any questions or suggestions.
