About Me

I am a finance professor at the University of Toronto since 2018. I study the impact of technology on trading, securities exchanges, and asset management, and I try to understand how we can leverage innovation to build better markets. My research was published in leading academic journals such as The Review of Financial Studies, Management Science, and Journal of Financial Markets.

I will be joining Haskayne School of Business at University of Calgary in July 2024 as Associate Professor (tenured).

FNCE 559 Tokenomics
How does decentralized finance (DeFi) create value? In this hands-on course we investigate the role of “tokenomics” – the economic engines driving DeFi protocols. Beyond grasping their economic impact, we study the market, regulatory and security risks inherent to DeFi protocols. We will gain a deep understanding of the Solidity language and smart contracts on Ethereum and acquire practical experience by developing and deploying a DeFi application from scratch.
