I have been working in the digital marketing space since 2010 building prediction and optimization products. Before that, did quant finance for a bunch of years including such storied places as Amaranth Advisors and WorldQuant where I was one of the original employees. This was the mid 2000s and a very exciting period in the field. Along the way I have spent many years in academia and produced a number of publications including some early work in Recommender Systems.
A theme in all my industrial work has been prediction and optimization as work product.
