My research in theoretical computer science mainly lies in the field of algorithms and computational complexity, which studies the inherent hardness in solving some computational problems. I am particularly interested in “total search problems”, which arise naturally in many applications, such as game theory, optimization, cryptography, and many more.

Research interests included the economics of past and current technological change, demographic history, institutional evolution, and topics in the economics of industrial organization with special reference to the micro-level sources of long-term productivity growth.
