Offer Description

The School VI of Medicine and Health Sciences comprises the fields of human medicine, medical physics and acoustics, neurosciences, psychology, and health services research. Together with the four regional hospitals, Faculty VI forms the University Medicine Oldenburg. Furthermore, there is a close cooperation with the University Medicine of the University of Groningen.

The Division AI4Health lead by Prof. Dr. Nils Strodthoff aims to fill

one PhD position (m/f/d) for 3 years
(E 13 TV-L, 85 %)
at earliest convenience. The position is suitable for part-time employment.

About us:

In the division AI4Health, we investigate methodological questions in the domains of self-supervised/label-efficient learning as well as explainability of deep neural networks (XAI) with particular focus on applications in the biomedical domain. Further information on the division is available at https://uol.de/en/ai4health .

Your tasks:

The position is part of the EU-project “QUMPHY”, a research project funded by European Metrology Programme for Innovation and Research (EMPIR) in cooperation with European metrology institutes and further university and non-university partners such as King’s College London and University of Cambridge. The project addresses uncertainty quantification for machine learning algorithms applied to photoplethysmography data. To this end, machine learning algorithms for different data representations are supposed to be compared for selected classification and regression tasks. Based on this, different approaches for uncertainty quantification are supposed to be adapted and implemented as well as appropriate metrics, which allow a quantitative comparison of the uncertainty information. Eventually, both components are supposed to be used for a comprehensive comparison in terms of both quantitative accuracy and uncertainty information. Project results are supposed to be deposited in public code repositories. The work for the advertised position will focus on the implementation/training of machine learning algorithms for photoplethysmography data as well as the adaptation and implementation of methods for uncertainty quantification as well as related documentation. The position allows working for a doctoral degree, which is also strongly encouraged.
