Ph.D. position in Clinical Data Science
Institute of Computer Science, Department of Systems Biology and Bioinformatics, University of Rostock
We are an interdisciplinary and international team of scientists located on the north-east coast of Germany. We are looking for a mathematician or computer scientist to develop algorithms for synthetic data generation in clinical taular datasets.
This is a full-time position for a research scientist that can be used to gain a Ph.D. The project is funded by the German Research Foundation (DFG). The start of the project is in spring 2023 (depending on the candidates’ availability, between March and May).
The recruited candidate is expected to develop Machine Learning algorithms and workflows to solve practical problems in clinical and biomedical data science. In particular, there are two research problems of concern: (i) The multimodal nature of clinical and biomedical data in patient stratification; (ii) The generation of synthetic tabular that can facilitate federated learning, helping overcome data privacy issues.
Questions and applications should be send to email@example.com (project leader) and firstname.lastname@example.org.
The recruited candidate is developing Machine Learning algorithms and workflows to solve practical problems in clinical and biomedical data science. In particular, there are two research problems of concern:
Problem 1: Clinical data is diverse in nature consisting of multiple modes such as tabular routine data, omics data, radiological images, and text data. The multi-modal nature of clinical and biomedical data makes it difficult to address tasks like patient stratification and decision-making.
Approach: The selected candidate will use diverse state-of-the-art machine learning techniques to form meaningful low-dimensional embeddings, which will be achieved by integrating data across different modalities. The developed algorithms and workflows will be deployed in the form of online tools.
Problem 2: Synthetic data generation often aids in addressing diverse practical problems prevalent in clinical data science. Such problems include scarcity of data, skewed data, and privacy issues hindering data sharing.
Approach: The selected candidate will build on existing in-house research on this topic, by developing, benchmarking, and deploying state-of-the-art algorithms for task-specific synthetic sample generation. The primary focus would be to generate synthetic tabular data that can serve as an alternative to real data, thereby facilitating federated learning.

Requirements for applicants
- Applicants must have a master’s degree in computer science, mathematics, or the physical and engineering sciences
- Applicants are required to have an excellent academic record.
- Prior knowledge of machine learning and deep learning, at least at a fundamental level.
- Excellent communication skills and academic writing skills are essential.
- Applicants are required to have excellent coding skills in Python.
- No one in our team works in isolation, and we are therefore seeking a team player. We employ and validate our work with partners in a clinical setting, which requires an interest in interdisciplinary collaborations.
- A deeper theoretical understanding of probability and statistics, linear algebra, and computational optimization is a plus.
- Knowledge of efficient computation is a plus.
- A GitHub profile and a knack for software-based tool designing and deployment is a plus.
- An interest in teaching is a plus. There are no teaching duties required with this post, but we care about sharing our expertise and also about the career development of the team members.
- Prior experience in scientific writing is a plus.
