In 1929 he got his habilitation, and in 1930 he was invited to the Stefan Batory University in Vilnius, Wilno Voivodship in Poland, to head the Department of General and Experimental Pathology of Faculty of Medicine (from 1930 to 1939).

Under his leadership the Vilnius Department of Medicine flourished, with many important publications, and with students who would go to become notable academics and physicians themselves (like professor J. Olszewski of Toronto, member of the Moscow Academy of Sciences M. Beklemishev, and J. Sztachelski, Poland's Minister of Health).

In May 1931 noting the lack of oncology-related health care in the Vilnius region he established the Institute of Oncology and Clinic, which constantly grew under his supervision.

In 1941 after German invasion of the Soviet Union, he continued to help various refugees, among them, Jews hiding from the Nazis, and working with medical services of Polish resistance organization Armia Krajowa.

[citation needed] The main fields of medicine in which he worked and published many publications were oncology, arthrology, cardiology, hematology and health-resort science.
