Rama Cont¶
Affiliation¶
Professor of Mathematical Finance. Held positions at Columbia University, Imperial College London, and the University of Oxford (Mathematical Institute).
Key contributions¶
- Order Flow Imbalance — co-invented with Kukanov and Stoikov; the foundational empirical model linking order book events to short-horizon price changes (price-impact-order-book-events).
- LOB modelling — stochastic models of limit order book dynamics, including the "Stochastic model of order book dynamics" (Cont, Stoikov, Talreja 2010).
- Systemic risk — contributed to models of contagion and systemic risk in financial networks.
- Rough volatility — work on pathwise stochastic calculus and rough paths in finance.
- Functional Itô calculus — mathematical framework for path-dependent functionals of stochastic processes.
