"I am a part of all that I have met;

Yet all experience is an arch wherethro’

Gleams that untravell’d world whose margin fades

For ever and forever when I move."  –Ulysses, by Alfred Tennyson

Overview of my research

Financial markets are used throughout the world to allocate capital to productive uses. As a result, financial markets have a significant impact on economic activity and the well-being of individuals. My research examines the role of a key group of participants in financial markets who account for nearly 70% of all investment in U.S. public companies: institutional investors. Specifically, my research examines how the actions of short-sellers, hedge funds, mutual funds, and exchange traded funds interact with various market frictions to affect real economic activity and the formation of asset prices.
