I am an Assistant Professor at the University of Oulu, and I am also a member of the European Lab for Learning and Intelligent Systems (ELLIS).
The focus of my research is on Intelligent Medical Systems, and I develop new machine learning methods for medical applications.
Earlier, I was a post-doctoral fellow at the Finnish Center for Artificial Intelligence and Aalto University working with Prof. Samuel Kaski and Prof. Simo Särkkä.
Before that, I was a post-doctoral fellow at KU Leuven, working with Prof. dr. Matthew Blaschko.
I earned my PhD during 2017-2020 (graduated with distinction) at the Faculty of Medicine, University of Oulu. My PhD thesis was nominated the best doctoral thesis of the year 2020. My advisors were Prof. Simo Saarakkala, PhD (primary), Dr. Jérôme Thevenot, PhD, and Prof. Esa Rahtu.
I was awarded a title of docent (i.e. habilitation) in Machine Learning for Medical Imaging on 01.02.2022.
Motivation. My group develops new AI methods for medical applications. The research that we are conducting is motivated by the following challenges that we either already face with medical AI, or will be facing in very near future:
