Short bio
My qualifications include BSc and MSc
in Mathematical Engineering from the Czech Technical University in Prague,
and a PhD in Economics from the University of Warwick (more
details here). I have spent 7 years at Imperial College London,
among others developing and teaching one of the core courses on the
MSc in Finance programme. I am currently a full professor of finance at the Cass Business School, City University London and a visiting professor of mathematics at Comenius University Bratislava, Slovakia.
Research interests
The theory of asset pricing
and risk measurement in incomplete markets is concerned with the methodology
and practical implementation of optimal hedging and pricing of derivative
securities in the presence of hedging errors. The standard asset pricing
theory assumes that all sources of risk are priced in the market; this
assumption is most famously embedded in the BlackScholes option pricing
formula. In reality, even extremely frequent hedging leaves a significant
amount of risk. In most models this risk is unaccounted for, as LTCM found
to its own detriment. My work proposes standardized measurement of risk
across different utility functions, allows for attribution of performance
among different assets (for example stocks and options) in a dynamic framework,
and provides extremely fast implementation of optimal dynamic hedge ratios
and risk measurements using Fourier transform.
