I lead economics at Unity (NYSE: U), where I work on ads auctions, machine learning, pricing and business models, and other strategic decisioning across the company. I am also a visiting scholar at the University of Hong Kong.

Previously, I was a visiting scholar in the Marketing Department at the Wharton School at the University of Pennsylvania, and a Principal Researcher in the Office of the Chief Economist at Microsoft Research, where I launched Azure Spot VMs, dynamically setting prices and allocation rules for Microsoft's cloud capacity.
