08 Postdoctoral Fellowship at KTH Royal Institute of Technology, Stockholm, Sweden

We are looking for a postdoctoral fellow to develop and improve models and codes for assessment of the liquid source term during severe accident (SA) of LWR systems. In particular, research will include assessment of the characteristics of the containment water pool by system code, thermodynamic and kinetic aspects of Cs and Sr chemistry including model development and its implementation to the system codes.  This project is contributing to the larger EU project SOCRATES which addresses the critical gaps in understanding of the liquid source term during SA and offers innovative solutions to mitigate and monitor the release of radionuclides into the environment.

The position as a postdoctoral scholar will be within the Division of light and matter within the Applied physics department at KTH. The department is part of the Stockholm center for physics, astronomy and biotechnology. The center groups physics related research within both KTH and Stockholm university which provides access to a multitude of research infrastructure as well as the opportunity for collaboration with a multitude of experimental as well as theoretical research groups.

We seek a highly motivated postdoc to conduct experimental research in the Quantum Matter group at the Applied Physics department KTH. Central to the research project is the study electronic structure and  the dynamics occurring at extremely short time periods, down to the femtosecond time scale (10-15 s). In your research, you will be part of a group investigating electronic structure and ultrafast transient states in quantum materials such as topological materials and superconductors. A primary tool is our newly commissioned time and angle resolved photoemission spectrometer (tr-ARPES). With tr-ARPES the electronic band structure of quantum materials will be mapped following ultrafast electronic and/or structural excitations. We have recently developed a new HHG source that delivers photon energies from 10.8 eV to beyond 25 eV at an energy resolution better than 20 meV. The combined high temporal, energy, and momentum resolutions will provide detailed information on dynamic processes previously not feasible to study experimentally. Of special current interest is the development of new spectroscopic techniques to study high temperature superconductivity. The research will also be carried out at national and international synchrotron light sources and in collaboration with other local and external groups.

Do you have a background within mechatronics, biomedical, mechanical, electrical, or computer engineering and research interests in medical robotics and human in the loop control – this could be a position for you. We are looking for an ambitious, collaborative, and structured person to join our team.

You will lead research efforts in human-in-the-loop control for medical robotics in the context of cardiovascular technologies. The goal is to innovate control systems for optimized interaction of soft cardiovascular pumps and wearable biofeedback systems with the human body. You will have the opportunity to critically assess the safety of the proposed control system for real-world application utilizing a hybrid mock circulation. The unique systems enables real-time testing in interaction with the human cardiovascular system dynamics across various patient groups. You are expected to publish in scientific journals in an independent way and to support the coordination of the research group and supervision of students.

Nuclear Power Safety (NPS) Division seeks engaged postdoc to study in-vessel corium melt retention (IVMR) in small modular reactor (SMR) of PWR type, and (ii) ex-vessel melt-coolant interactions and melt spreading. The project is supported by Swedish Radiation Safety Authority (https://www.stralsakerhetsmyndigheten.se/).  The IVMR research will be towards adaptation of the conventional IVR methodology developed for and used in the medium- and large-power PWRs and its further implementation in new SMR designs. The expected results are connected with demonstration of potential efficiency of the IVMR strategy, which can significantly improve SMR safety performance by preservation of integrity of reactor pressure vessel, i.e. the existing safety barrier.

The position is located at the division of process technology at KTH and will focus on CFD simulation of heat-transfer. It is part of our activity for sustainable processes and decarbonization of industry. The present project focuses on CFD simulations of chemically reacting flows with application to heat recovery. In this project, we consider the flow, turbulence, mixing, finite rate chemically reaction and conjugate heat-transfer in the simulations. The project will cover elementary and real type advanced heat-exchangers. We use both high-fidelity simulations to capture the details of the chemical associated with heat-transfer and commercial codes (ANSYS) for simulating the complex heat-exchanger. The work will consist of setting up simulations, meshing complex geometries, using super-computers, data analysis and presentation of the result. The data analysis might include some coding in python

To achieve rapid decarbonization of the industrial sector, technically efficient and cost-effective solutions integrating renewable energy sources, electrification of heat, and energy storage are deemed.  We aim to design and prototype different technologies, including low and high temperature thermal energy storage and integrated systems. The postdoc will contribute to the activities including TES unit development, laboratory testing and techno-economic analysis to identify optimal integration opportunities. Cooperation with industrial and academic national and international partners in the energy sector is planned. Candidates must have a documented background and interest in thermodynamics, heat transfer, and experimental methods and activities.

The Division of Decision and Control Systems is currently looking for 1-3 postdocs with a very strong background and interest in networked control systems, mathematics, and modeling. The successful candidates will join a project on developing novel mathematical and computational tools for the fundamental understanding and engineering design of emerging networked control systems, focusing partly on learning and resilient cyber-physical systems. A team consisting of the professors Henrik Sandberg, Karl Henrik Johansson, Cristian Rojas, and György Dán will supervise the work.

The Division of Decision and Control Systems conducts fundamental research in networked control systems, cyber-physical systems, system identification, and transport systems. Industrial projects involve partners such as ABB, Ericsson, and Scania. A large part of the research is funded by the Swedish Research Council, WASP, Digital Futures, Vinnova, MSB, Swedish Energy Agency or the EU. We have an extensive academic network and collaborate with researchers at Imperial College, Oxford, ETH, Caltech, MIT, and UC Berkeley, among others.
