Jonathan Disselhorst is a research engineer with 11+ years of experience at the intersection of medical imaging, image analysis, and machine learning, currently working at Siemens Healthineers in Lausanne. He holds a PhD in Medical Imaging and has a strong track record designing and applying convolutional neural networks for detection and segmentation across PET, MRI and CT, including multi-site and multi-parametric datasets. His research emphasizes assessing tumor heterogeneity by linking in vivo imaging with histology and omics, and he has built bespoke hardware and software tools—such as an image-guided milling machine and parametric map pipelines—to bridge imaging and tissue-level analyses. Experienced in production-oriented ML workflows (PyTorch, Python) and robust pre-processing (normalization, outlier detection), he also explores model stability under noise and distortion. Colleagues describe him as a hands-on scientist who combines deep domain expertise with practical engineering to translate complex imaging science into clinically relevant solutions.
