I am currently a postdoctoral researcher at Scripps Institution of Oceanography, where I'm using the SWASH model to understand the physics of infragravity waves from the breaker zone to wave runup. My primary research interests include observational coastal oceanography, infragravity waves, wave runup, science communication and education.
Other fascinating science: tides, beach-groundwater interaction, and sea level rise. When do I have the most fun? When I'm coding up elegant data displays and figures, and thinking up new ways to process and understand brand new observational data.
As beach vulnerability to erosion and associated coastal flooding increases with rising sea levels and more intense coastal storms, our understanding of storm waves and the resulting wave runup (e.g., waves generated by large North Pacific storms, hurricanes, tropical Storm Sandy) is still limited. My thesis field work obtained quantitative observations of the wave runup and changing sand levels in response to large ocean waves. Existing field observations of wave transformation from offshore to wave runup in large conditions are very sparse, reflecting the difficulty of working in this harsh environment. These observations were used to calibrate and improve a numerical model (SWASH) to evaluate its fitness for coastal planning and beach management in extreme conditions when shoreline infrastructure is most at risk.
