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 cotutelle programme supported by the French Government.
My advisors were Edita Pelantová and Christiane Frougny, the thesis
Nonstandard numeration systems and combinatorics on words was defended on 11/19/2010 in Paris.
Research Interests
 combinatorics on words
 nonstandard numeration systems
 robust statistics
