24 Postdoctoral Fellowship at Chalmers University of Technology, Gothenburg, Sweden

The postdoc position is focused on experimental work in advancing low-noise InGaAs HEMTs for cryogenic applications 1-100 GHz. Depending on the background of the applicant, the research can be focused on device physics and engineering or the full HEMT LNA.  We have international collaborations with US and South Korea and participates in the EU Chips JU project Move2THz for exploring InP HEMTs on silicon bulk.

Possible GNSS-related research topics can include, e.g., reference frames, crustal motion, glacial isostatic adjustment, atmospheric signal delays, ionospheric research, LEO-augmented GNSS, new space missions, etc. The Postdoc position is in the research group for Space Geodesy and Geodynamics. It is restricted to three years (2+1) with a review after the second year. Together we work to increase knowledge on how to best achieve a long-term sustainable planet. Our main working places are the Onsala Space Observatory, 40 km south of Gothenburg, and Chalmers University of Technology in Gothenburg.

One of the main projects in WACQT is designing and building a quantum computer with the ability to solve problems beyond the capabilities of even the best conventional supercomputers. Join us if you have expertise in device fabrication and characterization techniques and want to work in a world-class cleanroom, if you are motivated to collaborate with colleagues to build quantum computers and have a career in quantum technology, in academia or at an institute or a company.

We are looking for a postdoc to work in the field of geometric hydrodynamics, particularly incompressible fluid equations  in geophysical fluid dynamics (GFD). The research is both analytical and numerical: the central tool is Zeitlin’s spatial discretization enabled via quantization theory. Depending on the candidate’s interest, the direction can be more theoretical (e.g., theorems related to hydrodynamics and Zeitlin’s model) or more numerical (e.g., derivations, simulations, and numerical analysis of GFD models via Zeitlin’s discretization) or more programming-oriented (e.g., efficient implementation of GPU algorithms for Zeitlin-based numerical methods).

Magnetic levitation of superconducting microparticles is a platform that greatly decouples the center-of-mass motion of a levitated mechanical resonator from its environment. This platform will enable ultra-sensitive force and acceleration sensors, as well as quantum experiments with macroscopic objects of 10^13 atomic mass units. The goal of the project is to generate quantum states in the center-of-mass motion of levitated microparticles. We will make this possible by merging magnetic levitation of superconducting microparticles with superconducting quantum circuits. Coupling these two platforms will allow us to reach quantum control over the motion of the levitated particles.

The Division of Subatomic, High-Energy and Plasma Physics performs research on theoretical and experimental subatomic physics, mathematical and high-energy physics, plasma and fusion physics, as well as nuclear physics. This diversity of research topics allows us to connect fundamental questions about the particles and forces governing our Universe to energy-related research. The methods of our investigations are also diverse and complementary, and range from theory and computer simulations to experiments in subatomic physics. 

The postdoctoral project will be focused on the design of optimized generation schemes for tailor-made electron beam and radiation sources in laser-produced plasmas.

The postdoctoral project will be focused on developing theoretical and numerical models to simulate electron acceleration from magnetic reconnection, and to apply these models analyze extreme acceleration events and determine the key underlying mechanisms for efficient acceleration. The work will be performed in close collaboration with IRF, Uppsala and KTH, Stockholm.

In quantum optics, it is common to assume that atoms can be approximated as point-like compared to the wavelength of the light they interact with. It is only in the past few years that experiments (at Chalmers, MIT, and other places), with artificial atoms built from superconducting circuits, have shown that this assumption can be violated. These artificial atoms can couple to an electromagnetic field at several points, which can be wavelengths apart. The study of giant atoms and the interference effects that arise from their coupling points is still in its infancy, but it is attracting increasing attention. In this project, we aim to go from fundamental research towards useful applications of giant atoms in emerging quantum technology.

The project is carried out in the stimulating research environment of the Wallenberg Centre for Quantum Technology (WACQT), a 12-year, billion-SEK initiative started in 2018 with the purpose of advancing Swedish academia and industry to the forefront of quantum technology, and to build a Swedish quantum computer.

The WACQT team at Chalmers currently has about 80 members (faculty, permanent research staff, postdoctoral researchers, PhD students, and undergraduate students) and is expanding. WACQT is committed to promoting career development, diversity, and gender equality through networking and supporting activities.

We expect high independence in conducting research projects. We expect that you guide PhD students in conducting and publishing their research. Excellent communication and supervision skills are expected. We develop a range of digital tools and you are expected to lead developing those further. Furthermore, you are expected to support in writing research applications.

The push for open science means that scientific knowledge is increasingly disseminated both inside and outside academia: future scientists need the right tools to communicate with a broad and diverse audience. This requires advanced writing expertise and rhetorical flexibility, well beyond writing for academic purposes. Unfortunately, writing education at the graduate and post-graduate level seldom addresses this need: writing research has not investigated how to promote transfer of writing skills and the development of rhetorical flexibility in the training of future researchers.

For this postdoctoral position, we seek applicants who are interested in addressing this gap. We invite project proposals which use or develop established theories in writing research and educational sciences, and adopt an empirical focus with a rich methodological approach in the investigation of pedagogical practices and task development in writing.
Possible interesting areas of research include but are not limited to (1) research on genre pedagogy in academic settings with a focus on learning dynamics and/or teacher perspectives (2) research on writing transfer (3) research on pedagogical writing-task development, including multimodality, use of LLM/AI, and/or multilingual approaches, 4) research on science communication pedagogy. To address the proposed research questions, we welcome qualitative, quantitative, and mixed-method approaches, as long as the proposed approach is well described and justified, and demonstrates a focus on data richness.

An ongoing international collaboration and a pilot project on multi-genre pedagogy will provide the interested applicants with a strong and reliable support basis, but applicants will be able to develop their postdoctoral work according to their interests and skills, and are therefore encouraged to present creative projects.

The research group of Mikael Molin has in later years pioneered the molecular understanding of oxidants in protein homeostasis (a k a proteostasis). Because low levels of oxidants are produced endogenously and because they target protein synthesis, folding and degradation they have a profound impact on physiology and disease. Because of their role in feed-back regulating protein synthesis as a function of metabolism oxidants have also turned out to limit the productivity of cell factories. However, modern methods to measure ROS and expertise in redox signaling enables rational metabolic engineering to increase the productivity of yeast cell factories (Gast V, Appl Environ Microbiol, 2021; -, Bio-protocol, 2022).

Moreover, yeast cell factories transforming sustainable starting materials, such as lignocellulose, to fine chemicals sustain significant oxidative and acid stress that limit productivity. Interestingly, recent studies in the collaborating Nygård lab (Division of Industrial Biotechnology, Chalmers) has pinpointed a key role for genes involved in the dissociation of one of the major protein degradation complexes in cells, the ubiquitin-dependent proteasome, in acid resistance (Mukherjee V, mSystems, 2021), implicating further oxidative proteostasis networks in cell factory performance.

In this project you will take engineering further by incorporating modern oxidant/proteostasis probes, CRISPRi and high-throughout screening with the aim to develop resistant yeast cell factory strains able to produce higher titers of aromatic chemicals from sustainable starting material.

Our group works with chemically modified nanostructures for various applications. We are interested in developing a new kind of platform for trapping single or very few biological molecules. This will open up new possibilities for analyzing biomolecules and their function, which may ultimately lead to a better understanding of life on the molecular level.

More specifically, we want to study the behavior of proteins. For instance, we believe that the methods we are developing can be used to gain new insights on oligomer formation among certain proteins that are associated with diseases such as neurodegenerative conditions (amyloid formation). By investigating how a very small number of molecules, confined in space to the nanoscale, interact with each other we may be able to understand better how and why toxic oligomers form.

We are also interested in using our technologies to study enzymes, which are nature’s catalytic machines. Enzymes are very important for various applications in bioprocessing technology. A better understanding of how they operate, obtained by studying them one by one, can improve various areas of biotechnology and sensor devices.

Finally, the synthetic systems we are developing can be used to mimic biological processes, such as transport of proteins through the membrane surrounding the cell nucleus. By artificially reproducing such processes we can learn more about how the biological machinery works on the molecular level and construct biologically inspired devices in a “bottom up” manner.

As a postdoc, you would contribute to our work on the above topics, although your exact project is subject to discussion and new research directions may emerge. Our broad research field requires knowledge about advanced nanofabrication techniques, fluorescence microscopy and organic chemistry synthesis, among other things. (You are not expected to know everything when you start, but some topic relevance in your background is meriting.) You will work closely together with other PhD students and postdocs in the same research group.

To qualify as a postdoc, you must have a doctoral degree. Good recommendations from your previous supervisor are meriting. Similarly, good publications are meriting but not a formal requirement. The most important qualification is a true interest in science and a strong motivation to do research. Your thesis should ideally be from the fields of physics, chemistry or materials science. However, a PhD in other topics such as life science could also be a suitable background.

This position is supported by the Knut & Alice Wallenberg Foundation. You will study 2D structures using advanced electron microscopy including imaging, diffraction and spectroscopy. The microscopy provides site specific information with high spatial resolution and high precision that is crucial for the understanding of how to control the materials properties. Using our unique in situ capabilities you will directly correlate electrical, mechanical and optical properties to the detailed material structure.

The project will be carried out in close collaboration with partners that fabricate and characterise the properties of materials and devices, develop the theory for the mechanisms determining the properties and define the targeted performance of the devices.

We invite applications for a postdoctoral research position at Chalmers University of Technology, focused on electronic packaging of quantum processors. At Chalmers we are at the forefront of quantum technology. We are part of the European Project OpenSuperQ+ that is a large collaboration between European universities and research institutes in quantum technology. In OpenSuperQ+ we are investigating how to package quantum processors as they grow to 100 qubits and beyond. The initial appointment is for two years, and the desired starting date is fall 2024.

The specific goals of this research project are to develop novel labels/probes and nature-mimicking molecules for DNA/RNA systems, new improved techniques for biochemical and biological investigations and use these labels/probes, nature-mimicking molecules and techniques to study and enhance the function and delivery process of next generation drugs. Now the Wilhelmsson (Chemistry) and Höök (Physics) research groups, in collaboration with the research group of Margaret Holme (Life Sciences) and as part of FoRmulaEx, invites applications for up to two 2-year PostDoc positions in the field of biophysical chemistry and biophysics with an emphasis on enhancing the functional lipid nanoparticle(LNP)-assisted cellular uptake of RNA therapeutics.

The role primarily involves developing control and orchestration methods for confluent networking. In summary, the main goals are to improve capacity, energy efficiency, and latency by implementing advanced control of new physical layer solutions as part of the ECO-eNET project. This will involve efficient provisioning using both existing and new controllers for wired, wireless, and computing systems, as well as an AI-enabled orchestration layer. AI-driven service and network orchestration will use network sensing technology to gather environmental data, support applications, and optimize networks. The applicant will also be able to interact with our national and international network of collaborators from academia and industry.

While current magnetic refrigerators utilize rare earth element (REE) Gd or Gd-based compounds, which are highly critical and expensive, our project aims to develop robust alternatives using compositionally complex alloys. We’re looking for a postdoc with proven experience in magnetocaloric materials, and ideally, some familiarity with machine learning and/or additive manufacturing, to drive these innovations forward.

The project is positioned at the intersection of history of technology and energy history. The person employed will be working closely with an international research project funded NORDFORSK that aims to analyse how people and communities have lived with, through and shaped energy transitions throughout history. Applicants are invited to propose their own research project within this framework focusing on large energy infrastuctures, such as oil refineries, district heating, energy buildings and infrastructure afterlives. The Postdoctoral project will benefit from synergies with the division’s new research program on infrastructures in the modern and contemporary world.

An optical frequency comb is a laser source with evenly spaced, narrow frequency lines that maintain phase coherence across the spectrum. Microresonator frequency combs (microcombs) offer a chip-scale alternative to femtosecond mode-locked lasers, with advantages in frequency synthesis and metrology, from advanced communications to radio-frequency photonics.

Our group has demonstrated high-efficiency microcombs based on silicon nitride, with applications in coherent optical communications and nonlinear physics. We seek a postdoctoral fellow to explore new research avenues, including integration with active devices like microtransfer printing and hybrid techniques.

The Photonics Laboratory at the Microtechnology and Nanoscience Department (MC2) is a dynamic, international group of about 30 members. We conduct both fundamental and applied research in optoelectronics, nanophotonics, and fiber optic systems. Our state-of-the-art laboratory and in-house cleanroom facilities enable us to develop cutting-edge photonic devices.

We are looking for a highly motivated Postdoc to join our research group at Chalmers. You will be part of our organic electronics team and focus on electrochemical doping as well as wearable electronics. The goal of your project will be to study how the mechanical properties of conjugated polymers change during electrochemical oxidation/reduction cycles, and then design devices for wearable electronics that harness the observed changes in, e.g., stiffness or stretchability. You will work closely with several PhD students and Postdocs in our group, as well as with several external collaborators, and together study the mechanical, electrical and electrochemical properties of different types of conjugated polymers. The following recent review provides an overview of the research topics that the position will address: https://pubs.rsc.org/en/content/articlelanding/2024/cs/d3cs00833a

This position is focused on research in applications of image analysis in the biomedical area, e.g. developing automatic methods to interpret images from medical imaging systems. The project aims to develop models to evaluate, predict and prognosticate diseases, focusing on lung cancer mainly using computed tomography images (CT), and other medical imaging modalities such as x-ray, ultrasound, and nuclear medicine imaging. We aim to develop state-of-the-art methods for medical image analysis, based on key enabling techniques from machine learning, estimation, optimization, and mathematical modeling. Our research is highly multi-disciplinary and will be performed in close collaboration with medical researchers from the Sahlgrenska Academy at Gothenburg University and other medical institutions within Sweden and on the international scene.

This project seeks to advance computational studies of optical effects in modified base pairs and photoswitches when integrated into RNA/DNA environments. A key challenge is that electronic structure analysis typically relies on Kohn-Sham Density Functional Theory (KS-DFT), which, while widely used for its balance between accuracy and computational cost, has significant limitations. Foremost among these limitations is the tenuous connection between the energies of KS-DFT eigenstates (the orbitals) and physical reality as revealed, for example, in optical excitations.

Crucial leadups to this project is development of a formally exact and orbital-free DFT expression for the average energy of electrons, and beyond state-of-the-art DFT methodology exceptionally well suited to describe base-pair interactions. As a postdoctoral researcher in the Chalmers Molecular Spectral Design Initiative, you will help integrate these advances to develop a novel approach to chemical bonding analysis. This new method focuses on accurate calculations of the electron energy density and its connections to the total energy, molecular orbital theory, and key chemical concepts like electronegativity.

The research will primarily utilize periodic (plane-wave-based) DFT. However, analysis and design efforts will also incorporate extensive experimental spectroscopic data and insights from RNA/DNA nucleobase analogs and DNA-bound molecular photoswitches.
