Achievements:

I am doing my doctoral thesis within the Interdisciplinarity PhD Studies "Interdisciplinarity for Innovative Medicine - InterDokMed". The subject of my dissertation is the new functionalized biopolymers for medical applications. I work under the guidance of prof. dr hab. Małgorzata Witko, dr Maciej Guzik (Jerzy Haber Institute of Catalysis and Surface Chemistry PAS) as well as Prof. dr hab. Andrzej J. Bojarski (Jerzy Maj Institute of Pharmacology PAS). The main discipline of my work is chemistry, and the additional - medical biology.
