Dr. James G. Shanahan has spent the past 25 years developing and researching cutting-edge artificial intelligent systems splitting his time between industry and academia. He has (co) founded several companies including: Church and Duncan Group Inc.

In 2012 he went in-house as the SVP of Data Science and Chief Scientist at NativeX, a mobile ad network that got acquired by MobVista in early 2016. In addition, he has held appointments at AT&T (Executive Director of Research), Turn Inc. (founding chief scientist), Xerox Research, Mitsubishi Research, and at Clairvoyance Corp (a spinoff research lab from CMU). He also advises several high-tech startups (including Aylien, ChartBoost, DigitalBank, VoxEdu, and others).

Dr. Shanahan has been affiliated with the University of California at Berkeley and at Santa Cruz since 2008 where he teaches graduate courses on big data analytics, machine learning, deep learning, and stochastic optimization. He has published six books, more than 50 research publications, and over 20 patents in the areas of machine learning and information processing. Dr. Shanahan received his PhD in engineering mathematics from the University of Bristol, U. K., and holds a Bachelor of Science degree from the University of Limerick, Ireland. He is a EU Marie Curie fellow. In 2011 he was selected as a member of the Silicon Valley 50 (Top 50 Irish Americans in Technology).
