About Me

Currently a Senior Data Scientist at OpenX where I design, prototype, and deploy a wide variety of machine-learning models to support our programmatic advertising marketplace. Prior to that I was a member of the Caltech LIGO Laboratory Astrophysics group, where I worked on the detection and characterization of gravitational waves from colliding black holes that ultimately led to a 2016 Breakthrough Prize and the 2016 Gruber Cosmology Prize. My career is marked by nearly a decade of achievement in applying advanced statistical and machine learning techniques to hard problems in a variety of fields. In addition to a strong foundation in data science and programming, I have developed skills in theory, source simulation, time series analysis, digital signal processing, and experimental design.
