ERC-Funded Postdoctoral Position in Optimization for Inverse Electromagnetic Scattering
The Department of Physics and Technology is pleased to announce a vacant position of a Postdoctoral Fellow in the optics group in connection with the recently announced ERC starting grant project ‘Label-free 3D morphological nanoscopy for studying sub-cellular dynamics in live cancer cells with high spatio-temporal resolution (3D-nanoMorph)’.
UiT The Arctic University of Norway
UiT – Developing the High North
UiT is a multi-campus research univeristy in Norway and the northernmost university of the world. Our central location in the High North, our broad and diverse research and study portfolio, and our interdisciplinary qualities make us uniquely suited to meet the challenges of the future. At UiT you can explore global issues from a close-up perspective.
Credibility, academic freedom, closeness, creativity and commitment shall be hallmarks of the relationship between our employees, between our employees and our students and between UiT and our partners.
The Department of Physics and Technology houses the optics group at the main campus of UiT. The optics group has experienced a great surge in research, thanks to a constant flow of Horizon2020 funding through ERC and MSCA-IF projects and funding from research council of Norway through diverse projects. This has lead to a thriving multi-national (currently representing 8 nations) and multi-disciplinary research group, currently comprising of 4 principal investigators, 7 post docs, 7 PhD candidates, several master students and a multi-million dollar research infrastructure. There is a constant flow of international visiting experts.
The group members represent various disciplines like optics, photonics, fabrication, biology, mathematics, sensing, microscopy, nanoscopy, chemistry, computer engineering, electronic instrumentation, etc. The group’s core research activity targets development of cutting-edge technologies in nano-photonics, optics-based climate sensing, microscopy, and optical and computational nanoscopy. There is an emphasis on gender equality, cultural integration, conducive work environment excellence through cooperation and co-enabling, and support of growth and ambition of everyone in the group.
The appointment is for a duration of 2 years. Expected starting date of the position is 1st January 2020.
The postdoctoral research fellow will be a part of 3d-nanoscopy team, led by Assoc. Prof. Krishna Agarwal, who works on super-resolution microscopy, also referred to as nanoscopy. Agarwal is also the principal investigator of the aforementioned ERC project.
We offer an interesting project funded from the prestigious ERC Starting Grant, scientific independence, great potential of growth, and fantastic work environment within the stunning landscape of Tromsø.
The goal of the ERC project is to develop a new label-free nanoscope comprising of a novel innovative optical instrument that measures scattered light and a novel inverse scattering approach designed for biological cells and sub-cellular organelles, which together provide nanoscopic resolution.
The novel inverse scattering solver is a key component of the project and the postdoc will work on it with the following goals:
- Develop and study the forward model corresponding to the novel optical microscope
- Develop optimization strategies for the non-linear inverse solver for the phaseless scattering light measurements – these may include multi-scale optimization, multi-domain optimization, multi-objective and/or many-objective optimization, etc.
- Develop mechanisms of including problem/sample specific priors
- Design the objective functions and constraints for optimization
- Design iterative optimization solvers – these may include gradient bases, stochastic, or hybrid optimization approaches
- Involvement in supervising a PhD student on optimization for inverse problem
- Disseminate the work through scientific journal publications and conference participation
The work is related to development of optimization approaches of multi-objective and many-objective variety for solving extremely NP-hard, severely ill-posed, and non-linear inverse electromagnetic problem, which might require innovation in multi-scale, multi-region, multi-objective, and multi-constraint optimization solvers. A patent is being applied for the instrument and it is likely that the inverse scattering solver, including the optimization approaches, may be considered for patent as well. The project is likely to lead to commercialization research grants or technopreneurial start-up in the future.
The fellow will be encouraged and supported to build his/her resume towards their ambition in academic, technopreneurial, or mainstream industrial career. The fellowship also offers opportunity of mentoring PhD students in the team and involvement in teaching, if it is of interest to the fellow. There is an opportunity for the fellow to build his/her research network through inheriting the collaborations of the group.
Major collaborators, beyond UiT and directly relevant to the project, include USoton (UK), NTNU (Norway), UiO (Norway), IIT (Italy), IFOM (Italy), University of Campagnia (Italy), EMBL (Germany), NUS (Singapore), ASTAR (Singapore), BU (China), Sun Yat Sen University (China), and IIT (India). The fellow will also be encouraged to become a member of Digital Life Norway (DLN), a national platform for multi-disciplinary research with life sciences as a focus. DLN offers several courses and career development programs, which the fellow can participate in.
