About Me

Research Interests

In my work, I investigate algorithms aiding the decision process of radiologists for various diseases. Here, I mostly focus on deep learning-based approaches to medical imagery and face various problems occurring in real-world scenarios such as low amounts of annotations and/or label noise. Thus, I am especially interested in weakly and semi-supervised approaches for medical image analysis, which manage to thrive in these scenarios.

Practical Course - CV:HCI

I currently supervise the practical course "Computer Vision for Human-Computer Interaction".  Here, groups of three students each try to tackle various problems solvable by computer vision ranging from standard methods to SOTA deep learning algorithms.

If you are interested in the different types of problems we investigated in this course, please check the following:

Short CV

  • Research Assistant/PhD Student at Computer Vision for Human-Computer Interaction Lab,  Karlsruhe Institute of Technology, since June 2019
  • M.Sc in Computer Science at Karlsruhe Institute of Technology, 2016-2019
  • B.Sc. in Computer Science at University of Stuttgart, 2013 - 2016

Open Master/Bachelor Thesis Topics

I currently have a few ideas on weakly-/semi-supervised learning utilizing medical reports which we could discuss about and select a fitting topic from [pdf]. However, if you are passionate about deep learning with applications in medical imaging and have a particular topic in mind - please send me an email with a few sentences about yourself and your idea.

Pulmonary embolism describes a blockage of an artery in the lungs affecting about 430,000 people each year in Europe. Due to the high mortality rate of pulmonary embolism accurate detection is crucial. In this collaboration with the university clinic Heidelberg, we are directly working with practicing radiologists on the integration of image-based AI algorithms to aid the process of detecting pulmonary embolisms. For this task, we explore methods to visually aid radiologists by either improving image quality leading to easier manual detection by radiologists, or highlighting regions of high confidence of deep-learning-based algorithm.
