The RTG π3 is a collaborative project between mathematicians of the Center for Industrial Mathematics (ZeTeM); mathematicians in analysis, topology, and statistics; and applied scientists of the University of Bremen. We invite applications for a Ph.D. position (75% of a full position) in the area of inverse problems and data-driven methods in the framework of project R1-2: Inexact operator correction for inverse problems with applications in magnetic particle imaging.
Several imaging applications including magnetic particle imaging (MPI) suffer from an inaccurately known model, respectively forward operator. One workaround for linear operators is a full calibration with restrictions in possible resolution and accuracy. Two information sources thus can be combined to obtain an improved solution to the inverse problem, e.g., a mathematical model based on a time-dependent parabolic PDE and calibration data on a coarse resolution in MPI. In this project, we aim to develop and investigate explicit operator correction methods which consider both information sources for improved reconstruction methods for the imaging problem.
We are searching for an enthusiastic and committed researcher with an interest in inverse problems and learning-based methods as well as in developing and applying new mathematical models and algorithms. Within the research training group, the Ph.D. student will be part of the Industrial Mathematics group at the Center for Industrial Mathematics, working under the supervision of Dr. Tobias Kluth.
- M.Sc. or equivalent degree with excellent grades in mathematical sciences or related fields.
- Skills in scientific computer programming, preferably experience with Python.
- Experience in the field of inverse problems and machine learning is advantageous.
- Industry or research internships are advantageous.
- Fluency in English.
- Desire to work in an international and interdisciplinary team.
The position is for a fixed term of 3 years. The earliest starting date for each position in the research training group is 1 October 2022. The salary is according to the German federal employee scale TV-L E13, 75% of a full position (i.e., approximately € 1.900 – 2.100 monthly net income). This call is open until all positions are filled.
Applicants are invited to submit their letter of motivation including a reference to Ph.D. project R1-2, an extended CV including copies of certificates, a publication list (as far as applicable), one recommendation letter from a math professor, and contact information of two more scientists as possible referees.
The recommendation letter should be sent by the math professor directly to us (pi3-applicationprotect me ?!mathprotect me ?!.uni- bremen.de), while the application file should only include her/his name and affiliation.
All relevant documents, quoting the official reference number A 106/22, should be submitted by April 25, 2022,
– preferably electronically as a single PDF file to pi3-applicationprotect me ?!math.uni-bremenprotect me ?!.de – to the π3-coordination: Dr. Daniel Otero Baguer, Zentrum für Technomathematik, Universität Bremen, Bibliothekstr. 5, 28359 Bremen.
The University of Bremen has received several awards for its gender and diversity policies and is particularly aiming to increase the number of female researchers. Gender equality will be given special emphasis within this research training group. Applications from female candidates, international applications, and applications of academics with a migrant background are explicitly welcome.
Disabled persons with the same professional and personal qualifications will be given preference.
