Postdoctoral Fellowship (08) at Linkoping University, Sweden

The project’s contribution will lie at the intersection of random matrix theory and statistical inference theory, with applications in several fields of science. Special emphasis will be devoted to practical problems in economics and finance, like the construction of high-dimensional optimal portfolios.

Motivated by the widespread application of sample generalized inverses in practice when the dimension of the data-generating process exceeds the sample size, this project will contribute by developing the distributional properties of generalized inverses of the high-dimensional sample covariance matrix. The project’s findings will yield improved estimators of high-dimensional quantities by developing new linear and nonlinear shrinkage approaches. In particular, new estimators of optimal portfolio weights will be derived, leading to considerably more stable and less risky trading strategies.

For this position, we are seeking a highly qualified postdoctoral researcher who will contribute substantially to the quantitative research carried out in the division in collaboration with national and international partners.

The Soft Electronics group is an international team led by Prof. Klas Tybrandt and is part of the Laboratory of Organic Electronics (LOE). We develop composite materials, design concepts and devices for soft and deformable electronic and energy systems. Areas of special interest are sustainable energy harvesting/storage, bioelectronics and neural interfaces, and stretchable (semi)conductors. Many of our projects involves national and international collaborations including a variety of competences. Prof. Tybrandt is the recipient of the ERC CoG 2022 and Wallenberg Academy Fellow 2021.

At the Laboratory of Organic Electronics (LOE) we explore electronic and optical properties of organic semiconductors, biomaterials from the forest, and hybrid organic materials. Our activities span the range from basic research to commercialization, the latter carried out in close collaboration with the institute RISE. LOE currently has ~175 researchers and research students working within 13 research groups, each led by a principal investigator. Read more at www.liu.se/loe

Linköping University (LiU) conducts world-leading, cross-disciplinary research in fields that include materials science, IT and life science technology. LiU is one of the largest universities in Sweden and today has 46,000 students and 4,700 employees. The students are among the most desirable in the labour market and international rankings consistently place LiU as a leading global university.

Cellulose nanofibrils, isolated or in the wood cell wall, are unique building blocks for new materials, combining nanoscale dimension with excellent mechanical properties. New functionalities can be provided to such materials, which in combination with mechanical properties contribute strongly to sustainable development. Active research in this cellulose materials program includes materials design of multifunctional biocomposites, new polymers by in-situ polymerization, chemical cellulose surface modification, process-structure-relationships in colloidal systems, new biocomposites by controlled nanostructuring, high resolution structural characterization, structure-property relationships in novel composites as well as organic electronic devices.

As a Research Engineer you will serve as a supportive function for the researchers within the experimental activities at the Center for Social and Affective Neuroscience (CSAN). The conducted research focuses on neurobiological mechanisms, underlying affective disorders and addictions. 

Your tasks will consist of: 

• responsibility for animal handling, and work with animal models together with researchers in the group 

• molecular and biochemical analyses such as preparation of protein and nucleic acids from human and rodent tissue, ELISA, various PCR methods. 

The project focuses on electrocatalysis and electrolyzer system optimization for sustainable energy and chemical conversion. The research will involve reactions such as CO₂ conversion, water splitting, biomass-derived molecule upgrading, and other small-molecule transformations, with the aim of developing efficient, selective, and stable catalytic systems.

You will take a leading role in developing research activities that connect catalyst design, operando spectroscopic characterization, reaction mechanism investigation, and device-level performance optimization. The work may include catalyst synthesis, electrochemical testing, product analysis, operando spectroscopy, mechanistic studies, and optimization of electrolyzer configurations.

You are expected to conduct independent and collaborative research, publish in peer-reviewed journals, present results at international conferences, contribute to collaborations, and participate in the supervision of junior researchers. You may also contribute to the development of new experimental platforms and research directions within the group.

The candidate will join a newly established Pharmacogenomics research group within the Department of Biomedical and Clinical Sciences at Linköping University. The projects involve the identification of pharmacogenomic biomarkers from biobanks and clinical genotyping/sequencing data, and the development of machine learning methods to interpret the functional consequences of pharmacogenetic variants.

As postdoc, you will principally carry out research. A certain amount of teaching may be part of your duties, up to a maximum of 20% of working hours.

To advance bioelectronics and biointerfaces, we seek a postdoctoral researcher to contribute to the development of next-generation implantable bioelectronic systems for biomedical applications. Our work focuses on in situ formation of organic electronic materials in living environments, enabling new ways to create soft, adaptive, and spatially precise interfaces with biological tissue (see, for example, Strakosas et al., Science, 2023, https://doi.org/10.1126/science.adc9998).

This position addresses the emerging opportunity to bridge conventional implantable devices with bio-integrated, in situ formed electronic functionality, with particular relevance for neuromodulation and neuropharmacology, including applications in Parkinson’s disease and related movement disorders.

You will join a highly collaborative effort aimed at establishing new principles for electronic functionalization of living systems, where biological structure and signaling guide both the formation and operation of electronic materials.

The successful candidate will have strong problem-solving skills, be able to work effectively in a multi-disciplinary and international team and have excellent communication abilities. This is an exciting opportunity to work at the interface between chemistry, biology, and electronics in the highly collaborative and supportive Laboratory of Organic Electronics (https://www.liu.se/loe).

Your work will primarily be under the guidance of Asst. Prof. Xenofon Strakosas (https://liu.se/en/employee/xenst86) with additional guidance by Prof. Daniel Simon (https://liu.se/en/employee/dansi08), Organic Bioelectronics (OBE) group leader at the Laboratory of Organic Electronics.

If you are passionate about advancing the field of organic bioelectronics and meet the qualifications, we encourage you to apply and become a part of this transformative research journey.
