Stępień, Ewa


Ewa Stępień is a professor of medicine and medical physics at the Institute of Physics. Marian Smoluchowski at the Jagiellonian University. After receiving her MA and PhD in molecular and cell biology at the Jagiellonian University, she devoted the first 15 years of her career to the practice of laboratory medicine and the development of a number of molecular methods for the detection of hepatitis viruses and the application of new biomarkers of cardiovascular and kidney failure.  She is now pioneering development of application of positronium atoms as sensors of early tissue alterations at the intra-molecular level.

It is one of the pioneers who recognized extracellular vesicles (EVs), i.e. exosomes and microvesicles, as a suitable resource for biomarker discovery and drug delivery system design. Her work lies at the intersection of data analysis, clinical science, and molecular biology methods.

She also helped found companies like K2Biomedical, was the lead scientist, and funded the Theranoscope spin-off. She is a medical coordinator in the J-PET group for application cost-effective medical imaging.
