Post Doc in Formulation and Application of Priors in Spectral CT

jobbeskrivelse:
One Post Doc position is available in the Section for Scientific Computing at DTU Compute, the Department for Applied Mathematics and Computer Science at DTU. The period of employment is two years starting January 1, 2015 or as soon as possible thereafter. The position is affiliated with the project High-Definition Tomography (HD-Tomo) financed by the European Research Council. Responsibilities and tasks The overall goal of the HD-Tomo project is to utilize and further develop the enabling mathematical technology and computational algorithms to produce a new generation of tomographic reconstruction methods that can incorporate many different kinds of available prior information in order to produce high-definition reconstructions, i.e., sharper images with more reliable details. This Post Doc will develop new robust and efficient computational methods for spectral CT, where the reconstruction model must include information about the absorption’s energy dependence. The main challenge is to formulate and incorporate prior information about the spectral behavior into the reconstruction algorithm, in order to ensure a reliable reconstruction. This involves careful considerations of the formulation and parameterization of the forward model and the spectral information, how to apply compressed sensing techniques (sparsity), and how to represent large spectral 3D solutions. We will also develop efficient implementations of the methods and test them on real data, e.g., from CT scanners at DTU. The Post Doc is also expected to contribute to the section’s teaching in scientific computing (max 20% of the total time can be associated with teaching). Qualifications Candidates must have a PhD degree or equivalent. Preference will be given to candidates that have documented research experience in Scientific Computing and Applied Mathematics. A background in Optimization and Inverse Problems is especially relevant. The postdoc should have the ability to work both independently and as a team-player. Finally the postdoc must master the English language with proficiency. We offer We offer an interesting and challenging job in an international environment focusing on education, research, public-sector consultancy and innovation, which contribute to enhancing the economy and improving social welfare. We strive for academic excellence, collegial respect and freedom tempered by responsibility. The Technical University of Denmark (DTU) is a leading technical university in northern Europe and benchmarks with the best universities in the world. Salary and terms of employment The appointment will be based on the collective agreement with the Confederation of Professional Associations. The allowance will be agreed with the relevant union. The work place is DTU, Lyngby Campus. The period of employment is initially 1 year. Upon mutual agreement the position can be extended for 1 more year. Further information Further information may be obtained from Professor Per Christian Hansen, phone: +45 4525 3097, pcha (at) dtu.dk. Application procedure: Please submit your online application no later than November 30, 2014. Applications must be submitted as one PDF file containing all materials to be given consideration. To apply, please open the link "Apply online," fill in the online application form, and attach all your materials in English in one PDF file.
