## Biography

**Paul Wilmott** is a mathematician, author and financial consultant, specializing in derivatives, risk management and quantitative finance. He has worked with many leading US and European financial institutions.

Paul studied mathematics at St Catherine’s College, Oxford, where he also received his D.Phil. He founded the Diploma in Mathematical Finance at Oxford University and the journal *Applied Mathematical Finance*. He is the author of *Paul Wilmott Introduces Quantitative Finance* (Wiley 2007), *Paul Wilmott On Quantitative Finance* (Wiley 2006), *Frequently Asked Questions in Quantitative Finance* (Wiley 2009) and other financial textbooks. He has written over 100 research articles on finance and mathematics.

Paul Wilmott was a founding partner of the volatility arbitrage hedge fund Caissa Capital which managed $170million. His responsibilities included forecasting, derivatives pricing, and risk management.

Dr Wilmott is the proprietor of www.wilmott.com, the popular quantitative finance community website, the quant magazine *Wilmott* and is the creator of the Certificate in Quantitative Finance. He is a trustee of the charity Maths on Toast.

Paul Wilmott was a professional juggler with the Dab Hands troupe, and has been an undercover investigator. He also has three half blues from Oxford University for Ballroom Dancing. He was the first man in the UK to get an online divorce.

## Research interests

- Weaknesses of standard quantitative finance models: discrete hedging, transaction costs, incomplete markets, model error, etc.
- Model robustness: analysing models for sensitivity to assumptions
- Volatility: modelling volatility, testing standard and non-standard models
- Extreme markets: non-probabilistic approaches
- Exotic contracts: pricing and hedging, inherent but obscure risks
- Arbitrage: using classical tools in a non no-arbitrage framework, trading strategy optimization
