Szymon Płotka

I am an Assistant Professor at Faculty of Mathematics and Computer Science, Jagiellonian University in Kraków, Poland 🇵🇱. At Jagiellonian University, I have been working on machine learning, deep learning, and computer vision in applications to medical image analysis. I did my PhD at the Informatics Institute,University of Amsterdam,, the Netherlands 🇳🇱, where I was supervised by Clara I. Sánchez, Ivana Išgum, and Arkadiusz Sitek from Massachusetts General Hospital, Harvard Medical School.
