About me

I am post-doctoral fellow at the Finnish Center for Artificial Intelligence and Aalto University working with Prof. Samuel Kaski and Prof. Simo Särkkä. I am also a member of the European Lab for Learning and Intelligent Systems (ELLIS). Previously, 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, Finland. 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.

In addition to my academic activities, I am a co-founder and CTO of Ailean Technologies Ltd.

Research interests

I am currently working on AI-assisted design in the context of medical aplications. Generally, I am interested in Bayesian methods, semi-supervised, self-supervised, and active learning. My main application area is medical imaging. My translational contributions are in the fields of on musculoskeletal disorders, breast cancer, and dementia.

My research agenda is to investigate how to build medical AI systems that

Are multimodal
Use as little labeled data as possible
Predict how uncertain they are in their predictions
Interact with humans and other AI systems

Current PhD students

I am privelleged to supervise the following PhD students at the University of Oulu:

Egor Panfilov, MSc, 2022 (w. prof. Simo Saarakkala and prof. Miika Nieminen)
Huy Hoang Nguyen, MSc, 2023 (w. prof. Simo Saarakkala and prof. Matthew Blaschko)
Abu Mohammed Raisuddin, MSc, 2024 (w. prof. Osmo Tervonen),
Santeri Rytky, MSc, 2024, (w. prof. Jaakko Niinimäki and prof. Simo Saarakkala)
Terence McSweeney, MSc, 2024 (w. docent Prof. Simo Saarakkala and prof. Jaro Karppinen)
Elias Vaattovaara, MD, 2025 (w. docent Mika Nevalainen and prof. Simo Saarakkala)
