About me
I am a fifth year applied math PhD student at North Carolina State University. My main research involves global sensitivity analysis and uncertainty quantification for models that have high-dimensional inputs, function-valued outputs, are computationally expensive, stochastic, or some combination there in. I have experience working with both biological and physical models, including applications involving infectious diseases and multiphase multicomponent subsurface flow. I have spent two years as a graduate summer intern for Sandia National Labs (SNL) in Albuquerque, NM, where I collaborated on research in material sciences. I also really enjoy rock climbing, ultimate frisbee, and spending time with my Corgi, Vladimir (pictured with me, right).
