Olly Downs is Chief Scientist at Mindset Media, where he is responsible for the science, architecture and development of a web-based predictive analytics platform enabling ad-targeting to internet users based on attitude rather than behavior.   

Olly specializes in applying abstract analytical ideas from mathematical, physical and statistical science to problems in the real world; to date this has resulted in 18 US patents pending in the fields of Bayesian Prediction, Statistical Estimation, Outlier Detection, Real-Time GPS Data Processing and Quantum Computing.

Previously, Olly was Principal Scientist at INRIX, the first technology spin-out from Microsoft Research. At INRIX, Olly delivered a world-first in the provision of real-time traffic information using a nationwide network of GPS-enabled probe vehicles (named 2007 Breakthrough Technology of the Year by the Washington Software Alliance), and drove the design and architecture of INRIX’ dynamic Bayesian predictive modeling platform for traffic conditions, revolutionizing the traffic information industry worldwide. 

Olly’s work has included pioneering web-facing applications of predictive analytics and probabilistic reasoning for Pelago, Farecast and MSN in addition to offline analytics; including financial mathematics, quantum computing and Bayesian prediction, for L1 Partners, D-Wave Systems, Apollo Data Technologies, Microsoft Research, Barnes & Noble, Knight Ridder, Ryder and IGT. 

Olly has also spent time in research roles at Microsoft Research and Bell Labs.

Olly holds PhD and MA degrees in Applied & Computational Mathematics from Princeton University, and BA, MA and MSci degrees in Experimental & Theoretical Physics from the University of Cambridge, UK.  He has an Erdös Number of 3.
