Phd Student In Surgical Tool–tissue Modeling, 3D Reconstruction, And Soft

Your responsibilitiesThe PhD student's primary responsibility is to conduct original research on dynamic 3D modeling of surgical anatomy under tool–tissue interaction. You will work with multi-modal data acquired at OR-X, including CT, RGB-D sequences, tool tracking, and optical surface models, and use them to build methods that reconstruct and simulate anatomical changes during manipulation.The core research challenges include accurate 3D reconstructions that can be continuously updated from sensor data. Potential approaches include graph neural networks, NeRF representations, point-based and diffusion-based models, and advanced differentiable rendering frameworks such as Gaussian Splatting. The exact direction will be shaped based on the project's scientific explorations. n in user studies.The work is expected to produce methodological contributions documented through publications in leading venues such as MICCAI, IPCAI, or Medical Image Analysis. During the initial phase, the candidate will review the state-of-the-art and establish a structured multi-year research plan together with the supervisor. The PhD is embedded in the graduate school of the University of Zurich, which also involves serving as a teaching assistant for 1–2 courses per year.In particular, the PhD project will involve:Building multi-modal 3D reconstructions by fusing CT-based anatomical models with photorealistic or depth-based surface reconstructions from optical camerasDeveloping algorithms to integrate real-time camera observations into dynamic anatomical models to track tool–tissue interactionsInvestigating learning-based methods for dynamic anatomy modeling, including GNNs, implicit neural representations, and radiance-fielExploring simulation approaches ranging from FE simulation to learned–physical modelsPerforming user studies to evaluate the usefulness of the developed methods in a surgical training settingCollaborating with surgeons and engineers to ensure translational relevanceDisseminating results through scientific publications, patents, and prototype demonstrationsYour profileYou hold an excellent MSc degree in computer science, robotics, or electrical engineering with a strong background in computer graphics, simulation, and computer vision. You combine excellent programming skills with experience in medical imaging and camera hardware.We are looking for candidates who demonstrate:Solid understanding of generative models and proven experience in working with multimodal dataStrong understanding of 3D geometry processing, reconstruction, registration, or sceneExperience with modern 3D learning paradigms such as graph neural networks, implicit neural representations, or point/voxel-based modelsFamiliarity with physical simulation concepts or deformable modeling (finite elements, mass–spring models, or physics-informed models) is an assetPractical experience with computer vision, camera calibration, and tracking, and proficiency in relevant libraries (e.g., OpenCV, Open3D)Familiarity with AI/ML frameworks (e.g., PyTorch, TensorFlow) and medical image analysis libraries (Slicer3D, MONAI)Excellent communication skills in English (German is an asset), combined with initiative, problem-solving ability, and teamworkWhat we offerOur employees benefit from a wide range of attractive offers.
