[EXPIRED] The Capital Region of Copenhagen is looking for a PhD candidate in Machine Learning for Neuronal Feature Identification in 3D Microscopic Imaging - DTU Compute

Do you want to join a multidisciplinary team working with a new 3D optical imaging technology and develop machine learning models to map in the brain neuronal and cellular objects, their geometry, density and organization? Are you interested in learning about 3D imaging analysis, brain anatomy, collect your own high-quality microscopic data as well as generating synthetic cellular environments to evaluate and train your model? Are you intrigued by solving challenges working with big data? Are you eager to develop innovative solutions in a groundbreaking project at the intersection of neuroimaging and machine learning? If yes, we encourage you to apply and join our team!

DTU Compute’s Section for Visual Computing is opening a PhD position in Machine Learning for Neuronal Feature Identification in 3D Microscopic Imaging. The project is financed by the Independent Research Fund Denmark – and aims at modelling neuronal anatomical compartments from 3D Light-Sheet (label-free- and fluorescence- based) microscopic imaging data. The project will also be carried out at the Danish Research Centre for MR at Copenhagen University Hospital Hvidovre, and in collaboration with IRB Barcelona: Institute for Research in Biomedicine (Barcelona, Spain).
