I am an Applications Engineer at MathWorks. My MATLAB addiction began in undergrad while I was attempting to learn Fortran, then someone introduced me to MATLAB. I immediately picked it up and never looked back. These days I travel the country talking with folks of various backgrounds about how MATLAB can make their work easier.

Professional Interests: data analytics, parallel computing, machine learning, big data
