I graduated in Finance and Accounting from the University of Lodz. Since 2016, I have been working at the Department of Corporate Finance. My scientific interests concern the bankruptcies of enterprises and corporate finance.
I have an accounting specialist certificate issued by the Accountants Association in Poland and a work experience in the finance departments of international corporations. In addition, I have teaching experience both in Poland and abroad (conducting lectures as part of Erasmus + Staff Mobility - Teaching Assignments and Summer School).
