## About

### Overview

Prof. Černý received his MSc in Mathematical Engineering from the Czech Technical University in 1994 and PhD in Economics from the University of Warwick in 1998. Before joining Bayes Business School (formerly Cass) in 2005, he worked at Imperial College London. His main research agenda recognizes that financial markets are inherently incomplete.

Aleš has given a number of invited talks in Europe and U.S. on the subject of incomplete markets and published a textbook on the topic, now in its 2nd edition, with Princeton University Press. His research has appeared, among others, in The Annals of Probability, Bernoulli, The Economic Journal, European Journal of Operational Research, Journal of Derivatives, Mathematical Finance, Quantitative Finance, and SIAM Journal on Control and Optimization. He is an associate editor for the Review of Derivatives Research.

Aleš has consulted for government organizations in the UK and Japan in the area of optimal lifecycle asset allocation with particular focus on pension and real estate investment.
