Research

I am an Assistant Professor and the chair of the Department of Appplied mathematics at the Faculty of Information Technology of the Czech Technical University in Prague.

I did my Ph.D. at Czech Technical University in Prague and University Denis Diderot - Paris VII participating in the co-tutelle programme supported by the French Government.

My advisors were Edita Pelantová and Christiane Frougny, the thesis Non-standard numeration systems and combinatorics on words was defended on 11/19/2010 in Paris.

Research Interests

• combinatorics on words
• non-standard numeration systems
• robust statistics
