Polish

I studied for three years at a Polish University (Warsaw University and Maria Curie Sklodowska University). I have a certificate of a teacher of Polish and my level is close to a native speaker.

Russian

I am a native Russian Speaker. I used to work at a Language School and taught Russian and Business Russian to foreigners before I started my PhD.

STATA

I have been actively using STATA for financial economics research. I have taken Econometrics I, Econometrics II, Econometrics III and Financial Econometrics class where I used STATA for my homework and projects. STATA is a very powerful statistical tool. It is most popular with academics in social science fields and I can help students master STATA and its applications.
