Some of his recent work has focused on: high-frequency market microstructure as well as the design of portfolio trading systems and algorithms; the interface between social learning and revenue optimization; the economics of services that are prone to congestion, including cloud computing; and the application of quantitative pricing and risk management in the residential real-estate market.
