Thomas Michael Alscher

Thomas Michael Alscher is a PhD fellow and Guest Researcher at the Department of Computer Science, Faculty of Science, University of Copenhagen, specializing in the Image Analysis, Computational Modelling and Geometry research group.

His research focuses on:

• Physics-integrated deformable image registration
• Collision constraint handling in medical imaging
• Computational geometry for discontinuity management
• Diffeomorphism-based transformation models
• Realistic simulation of anatomical structures

Alscher's work bridges computational mathematics and medical imaging, developing frameworks that enforce physical plausibility during image alignment. His approaches prevent anatomical intersections in deformable registration by incorporating collision constraints and discontinuity management, significantly advancing medical image analysis where structural integrity is critical. This research enables more accurate surgical planning and diagnostic applications through physics-aware computational models.

His 2023-2025 publications demonstrate consistent innovation in physics-constrained registration, with his 2025 PhD thesis establishing foundational methodologies later refined in journal publications. The work shows strong interdisciplinary connections between computer vision, biomechanics, and clinical imaging.

Alscher collaborates extensively with researchers including Petersen, Lauze, Erleben, and Darkner within Copenhagen's computational imaging ecosystem, contributing to the department's leadership in geometric image analysis.
