Medical Data Science
Background
Data sciences and machine learning in medical research
Research in medicine changed substantially in recent years. Modern high-throughput technologies, such as RNA sequencing provide data of unprecedented amount and quality. Multiple molecular layers of information, such as the transcriptome and methylome, can be assessed within individual cells, and ven with spatial resolution.
These new data provide a valuable resource to gain insights into diseases and their patho-mechanisms. Computationally, methods have to deal with an overwhelming complexity. High-dimensional statistics and machine learning can help to resolve this complexity. However, yet, appropriate methods are rare, and need to be futher developed or adapted to deal with new, upcoming biomedical data.
Research Foci
We focus on developing computational approaches to deal with new, upcoming high-throughput data in the context of biomedical research. This comprises the development of machine learning methods for clinical decision support, and for the inference of molecular networks and mechanisms. Further, we are highly interested in applying state-of-the-art methods to solve questions that arise within research collaborations. Here, our focus is cancer research and kidney metabolomics.
