Wladislaws professional career began when she was hired by  (Indústrias Reunidas Francisco Matarazzo), but she was determined to go to graduate school.

Blanka got a grant from the British government to conduct postdoctoral studies at the Imperial College London on organic electrosynthesis. In the following decade, Wladislaw researched with organic electrochemistry, again with sulfur compounds. Returning to this field of study in 1971, she would at the same time be promoted to become a full time professor at USPs Institute of Chemistry and in 1975 started the Universitys Department of Fundamental Chemistry.
