Postdoc in Goal-Oriented Uncertainty Quantification for Inverse Problems at DTU Compute

DTU Compute’s Section for Scientific Computing invites applications for a 2-year Postdoc position starting June 1, 2020 or soon thereafter. The position is associated with the research initiative CUQI financed by the Villum Foundation.


The Section for Scientific Computing at DTU Compute performs interdisciplinary research in mathematical modeling, numerical analysis and computational methods aimed at complex and large-scale problems in science, engineering and society. The section's expertise includes many of the aspects of computational science, from modeling of physical phenomena to developing, analyzing, and implementing methodologies for the solution of real-life problems. Our research focuses on functional analysis; partial differential equations; matrix computations; inverse problems and imaging; optimization and control; and computational mathematics – with applications in, e.g., energy systems and engineering design.


Project Description

Uncertainty Quantification (UQ) allows us to characterize and study the sensitivity of a solution taking into account errors and inaccuracies in the data, models, algorithms, etc. We focus on inverse problems (e.g., image deblurring, tomographic imaging, source reconstruction, and fault inspection), and the overall goal of the CUQI project is to create a computational platform, suited for non-experts in academia and industry.


In many applications, the end-goal is to compute a Quantity of Interest (QoI) defined on the solution to an inverse problem, such as the segmentation of a deblurred image, the dynamics of an object in CT imaging, or the location of details in a CT or EIT reconstruction.  Performing UQ on a QoI is often referred to as Goal-Oriented UQ, and some core problems here are 1) how to develop efficient computational algorithms and 2) whether we can compute the QoI directly from the data.


Our activities in Goal-Oriented UQ are performed in a collaboration with the Department of Mathematics, Virginia Tech, Blacksburg, VA. The Postdoc must spend some of the time at Virginia Tech.


Responsibilities and tasks

The present postdoc project will focus on theoretical and computational aspects of Goal-Oriented UQ, and we will study how to incorporate these types of problems in a general computational platform. The project involves development of theory as well as computational algorithms, plus evaluation of the results on selected inverse problems, e.g., sound source reconstruction, electrical impedance tomography, or image analysis.


The applicant will be responsible for developing practical models and methods for Goal-Oriented UQ with an eye to incorporating these types of problems in a general computational platform for UQ for inverse problems. The applicant will work in a team of PhD students, postdocs and faculty members in the section, and must contribute with research towards the overall goals of the CUQI project. The applicant must be prepared to spend time at Virginia Tech. Finally, the applicant is expected to give limited contributions to teaching and training activities as well as supervision of students.


Candidates should have a PhD degree or equivalent in scientific computing, computational science and engineering, applied mathematics, or equivalent academic qualifications. Preference will be given to candidates who can document research in uncertainty quantification, inverse problems, numerical algorithms and scientific computing. Furthermore, good command of the English language is essential.
