PhD: Hollow Core Fibers: Enabling Optical Links for 6G/Quantum Networks

Department of Molecular Sciences Third-cycle subject area: Chemistry Description of the doctoral project Do you want to work in a project that aims to replace fossil sources with forest raw materials for the production of biomaterials? Are you interested in immersing yourself in molecular interactions at the atomic level with advanced analytical instruments? Do you want to work with a whole group of researchers who share these interests? If so, this could be a PhD position for you. The overall goal of this PhD project is to enzymatically modify glycans from hemicellulose to produce bio-based crosslinkers for applications in adhesives, hydrogels and other crosslinked materials. However, many materials that we consider bio-based, such as wood fibreboards, hydrogels and stabilizers from non-fossil polymers, still rely on crosslinkers that have fossil origins and are often very harmful chemicals. Fibreboards for furniture, construction and insulation typically contain around 9% glue consisting of urea formaldehyde. Formaldehyde is classified as a known human carcinogen and its emissions from fibreboards are a major concern. Oxidative enzymes will be used on hemicellulose substrates, such as xyloglucan and glucomannan, to obtain aldehyde and ketone functions on the sugar ring in parallel with a partial degradation to oligosaccharides. The expected result is a collection of non-toxic, bio-based crosslinkers that can potentially replace formaldehyde and similar fossil-based crosslinkers. About the position You will be part of a research group conducting research in organic chemistry and biotechnology with a focus on structural analysis of enzymes and carbohydrate substrates using NMR spectroscopy, as well as the development of new methods for studying interactions between proteins and carbohydrates using NMR spectroscopy. The project includes a lot of laboratory work and will be carried out with an advanced level of characterization using NMR spectroscopy and mass spectrometry to be able to draw conclusions about the structural composition of the crosslinkers and the crosslinked materials. To achieve these goals while ensuring a productive and enriching environment, the project includes supervision in organic chemistry, enzymology and wood technology. The position also includes teaching up to 20% of the time. Requirements To meet the general entry requirements you must have: been awarded a second-cycle (Master’s) qualification; satisfied the requirements for courses comprising at least 240 credits of which at least 60 credits were awarded in the second-cycle, or acquired substantially equivalent knowledge in some other way in Sweden or abroad (Higher Education Ordinance 1993:100, Chapter 7, Section 39). Specific entry requirements for the third-cycle courses and study programme in chemistry: To meet the specific entry requirements, you must have at least 60 HEC in chemistry-related subjects (general, analytical, inorganic, organic and physical chemistry as well as biochemistry). This must include a degree project and at least 30 HEC must be at second-cycle level. You must also meet the equivalent English language requirements as those necessary for the Swedish upper-secondary qualification Engelska B/6. Your profile We are looking for a highly motivated candidate who has a master's degree in a field relevant to the position, for example in organic chemistry, biotechnology, molecular biology or equivalent. A focus on biochemistry or organic chemistry with experience in laboratory work are valuable merits, as are experience in NMR spectroscopy and/or protein expression and purification. Great emphasis is placed on personal qualities such as collaborative skills, analytical and problem-solving skills, as well as the ability to work independently. Good knowledge of English (both spoken and written) is required. About us You will be placed in the subject of organic chemistry at the Department of Molecular Sciences, SLU, Uppsala. The department consists of about 100 employees and, together with three other departments, forms an inspiring research environment at the BioCenter on the Ultuna campus in Uppsala.

The position is linked to AIMARIA – Accelerating Innovation in Marine AI-Powered Bioprospecting, a Horizon Europe Innovation Action coordinated by NTNU.   AIMARIA combines omics, bioinformatics, artificial intelligence, synthetic biology, bioprocess development and sustainability assessment to accelerate the discovery and sustainable production of marine and aquatic natural products. At NTNU, a central part of the project is the development of more predictable and efficient methods for the refactoring and heterologous expression of biosynthetic gene clusters (BGCs).   The PhD project will investigate how regulatory DNA elements, BGC architecture and microbial host selection influence the expression of complex biosynthetic pathways. Molecular biology, microbial strain engineering and synthetic biology will be combined with AI-supported design of promoters, 5′ untranslated regions and other regulatory elements. The resulting data will be used to establish more predictable design principles for BGC expression and to support iterative AI-guided design–build–test–learn cycles.  The precise scope of the doctoral project will be refined according to the candidate’s qualifications, the BGCs prioritised in AIMARIA and the scientific development of the project.   The PhD candidate will work closely with a researcher recruited to the same scientific activity and with national and international partners in the AIMARIA consortium.
