I am a Principal Data Scientist and the Chief Architect in the Instrument and Data Systems section, at the Jet Propulsion Laboratory (JPL) in Pasadena, California. I also am Director of the Information Retrieval and Data Science Group (IRDS) and Adjunct Associate Professor in the Computer Science Department within USC's Viterbi School of Engineering.
At USC, I teach CSCI 599: Content Detection and Analysis for Big Data, a new course in the Data Science track. I used to teach CSCI 572: Information Retrieval and Search Engines and CSCI 578: Software Architectures.
I wrote the Tika in Action book with Jukka Zitting and published by Manning Publications. Tika in Action is the definitive guide to a popular software framework for content detection and analysis that I co-invented (with Jérôme Charron) called Apache Tika.
