About

Software developer for CIWRO. I assist scientists in transitioning world-class weather radar research into algorithms that run operationally on NEXRAD weather radars. I've successfully transitioned two algorithms in my short time (~ 1 year) focusing on the R2O pipeline with more on the way! What kind of problems can I help you solve?
