General project description

My Ph.D. project is a research in the broad field of Econophysics. The aim is the better understanding of financial market mechanisms with the use of methods and tools borrowed form theoretical physics. My main interest is the way "information" is used by the actors on the stock market, and is being built into the prices.

I am interested in the microstudy of large price changes, ie. the analysis of the limit order book in the environment of extreme price jumps. You can find details on this project here.

Correlations between the individual assets are the main factors in classical portfolio management. The most important questions I am studying is
* the evolution of stock return cross-correlations through the last two decades, as market processes change
and
* determining the dependence of the correlation coefficients on the sampling frequency of data (Epps effect).

An other project I have been working on (in collaboration with Enrico Scalas, Juergen Huber and Michael Kirchler), is about the value of information on a double auction stock market. You can find more details about this work here.
