This PhD project is part of ECOPHARM, a research project funded by the Knut and Alice Wallenberg Foundation (Wallenberg Academy Fellows 2025) and is based at the Department of Aquatic Sciences and Assessment, SLU Uppsala. The overarching aim of ECOPHARM is to decipher the mechanisms driving PDP interactions with conjugative plasmids and bacterial hosts, and to understand their impact on antibiotic resistance gene transmission in aquatic environments. As a PhD student, you will investigate the diversity, ecology, and functional interactions of plasmid-dependent phages in aquatic ecosystems. The work will combine environmental sampling, cultivation-based approaches, metagenomics, genome analysis, and experimental infection assays. You will work in a dynamic and internationally connected research environment at the intersection of microbial ecology, virus-host coevolution, and AMR research.

PhD Student in Multimodal Machine Learning for Energy Storage Materials
Department of Chemistry - Ångström conducts research and education in chemistry. The department has 270 employees and generates annual revenue of 300 million kronor. The department's six programs conduct highly successful research of international caliber. We have a large number of externally funded research projects, often with international collaboration, and we see continued strong growth within our field. The department provides education within engineering and civil engineering programs as well as master's programs. Project Description The development of tomorrow's energy storage materials relies on a fundamental understanding of how their chemical composition and structure change during operation in applications. No single method can capture the complete picture. Instead, researchers must rely on multiple complementary techniques, each providing an incomplete and indirect view of the same underlying process and which are traditionally interpreted manually and separately. Multimodal machine learning offers a principled alternative: integrating heterogeneous data streams from both experiments and simulations into a unified, physically grounded model. The project focuses on developing such a framework and applying it specifically to electrode/electrolyte interfaces in batteries, where surface-sensitive X-ray scattering techniques (X-ray reflectometry, GISAXS, and GIWAXS) and electrochemical quartz crystal microbalance with dissipation monitoring (EQCM-D) are combined in operando experiments. The core of the methodology is data assimilation, where the interface's underlying properties (mass, volume, density, porosity, and morphology) are treated as a latent state evolving in time, with each measurement technique contributing a noisy and incomplete observation through its own forward model. The work encompasses sequential Bayesian inference, deep state-space models, and uncertainty-aware representations trained on both experimental data and simulations, such as phase-field simulations of metal nucleation and growth coupled to lattice-Boltzmann modeling of the quartz crystal's acoustic response. Machine learning-accelerated surrogate models make these simulations sufficiently fast to function as transition and observation operators in the inference engine. Finally, the learned latent space is analyzed to extract physical meaning, and the models' generative capability is leveraged to translate data between techniques. The goal is an interpretable and uncertainty-quantified model of how interfaces form and grow, deepening understanding of metal deposition and surface passivation in Li-, Zn-, and Cu-based systems, and transferable to other materials and analytical techniques. The PhD student's task is to develop and implement this framework in close collaboration between chemistry and computer science at Uppsala University and together with our German partners. This involves building and validating inference and simulation pipelines, actively participating in planning and conducting operando experiments – including measurement campaigns at the synchrotron facility PETRA III (DESY, Hamburg) – and developing deep expertise in probabilistic machine learning, data assimilation, scientific computing, and analysis of electrochemical interfaces. The PhD student's focus is research. Some teaching responsibility may be assigned but will not exceed 20% of total working time. The PhD student will also take graduate courses closely connected to the project's research themes. We are looking for a highly motivated person who will contribute to high-quality scientific work in a multidisciplinary research environment, aiming to publish results in leading scientific journals and present them at both national and international conferences. Qualifications Required Applicants must have: - completed a degree at an advanced level, or - completed course requirements of at least 240 credits, of which at least 60 credits at advanced level (of which 15 credits constitute independent work), with content relevant to doctoral studies, or - in some other way, within or outside the country, acquired substantially equivalent knowledge - very good knowledge of English, both spoken and written - a degree at an advanced level or equivalent as described above in chemistry, materials science, computer science, applied mathematics, engineering physics, or a related field - the ability to express yourself clearly, document your work, and contribute to the community in a research environment Great weight will also be placed on personal qualities such as good collaboration skills, drive, and independence, as well as how the applicant, through their experience and competence, is assessed to have the ability to manage doctoral studies. Desirable/Meriting Additional Qualifications Practical experience with probabilistic machine learning, Bayesian inference, generative models, data assimilation, or scientific computing is meriting, as are strong programming skills (e.g., Python, PyTorch, or JAX). Experience with electrochemistry, battery research, X-ray scattering techniques, or analysis of experimental time series data is also advantageous.

PhD Student
Department of Plant Production Ecology Doctoral Field: Biology with specialization in Ecology. Description of the PhD Project: Crop production faces increasingly significant challenges due to multiple interacting stress factors, including drought, heat, limited nutrient availability, weeds, pests, and diseases. Genetic diversity in crops can strengthen resilience under such conditions, but how this resilience is expressed depends heavily on environment, cultivation techniques, and management. Cultivation methods using cover crops or undersown intercropping can contribute to sustainability by providing valuable ecosystem services such as regulation of weeds, pests, and diseases, nitrogen fixation, and preservation of soil health and fertility. However, there is still limited knowledge about how genetic diversity in crops and cover crops or undersown intercropping interact to reduce the effects of multiple stress factors, which represents an important knowledge gap that this project aims to fill. The project will investigate how different cultivation methods affect the resilience of main crops, particularly wheat and peas, against multiple stress factors. You will study how different cultivation methods affect the response of various varieties or genotypes under varying growing conditions, with particular focus on the interaction between variety/genotype, environment, and cultivation method. The goal is to increase understanding of how cultivation methods affect different crop genotypes' resilience to multiple stress factors and to identify promising combinations of varieties/genotypes and cultivation methods that can contribute to stable yields and good productivity under low-input growing conditions. Field experiments will be conducted comparing different cultivation methods. Field measurements will include crop development, phenology, yield, and quality characteristics, as well as documentation of a broad spectrum of abiotic and biotic stress factors such as drought, heat stress, nutrient deficiency, and occurrence of weeds, pests, and plant diseases. Surveys of biological diversity, microbiome analyses, and environmental observations will provide additional evidence for assessing the effects of different cultivation methods and for evaluating crop performance. As a PhD student in this project, you will gain broad research experience in conducting field experiments, data processing, statistical analysis, scientific writing, and communication of research results. You will work in close collaboration with researchers at SLU and within a European research consortium. This collaboration provides excellent opportunities to develop your scientific expertise, build an international research network, and contribute to research across national and disciplinary boundaries. Qualifications Master's degree or equivalent in agronomy, plant science, plant biology, plant ecology, plant breeding, agricultural science, or a related field Documented experience with working with plants, crops, or agricultural systems Strong knowledge in plant ecology and understanding of its importance for sustainable crop production and cultivation. Documented experience with statistical data analysis Good ability to communicate in both speech and writing in English Meritorious Experience Documented experience with crop phenotyping, plant physiology, or evaluation of genotypes Documented experience with field assessment of weeds, pests, diseases, or environmental factors Documented experience with scientific writing and scientific communication Valid driver's license for Sweden We place particular emphasis on personal qualities. You should be able to work both independently and in collaboration with others, take own initiatives, handle complex tasks in a structured manner, and contribute positively to an inclusive work environment that encompasses multiple disciplines and countries.

PhD Student in Agroecological Crop Management
Department of Crop Production Ecology Research subject: Biology with specialisation in ecology Description of the doctoral project Crop production is increasingly challenged by multiple, interacting stresses, including drought, heat, nutrient limitations, weeds, pests, and diseases. Crop genetic diversity can strengthen resilience under these conditions, but the expression of resilience depends strongly on the environment and on how crops are managed. Service crops, used as an agroecological management practice, can provide valuable ecosystem services, such as the regulation of weeds, pests, and diseases, as well as nitrogen fixation and the maintenance of soil health and fertility. However, there is still limited understanding of how crop genetic diversity and service crops interact to alleviate multiple stresses - an important knowledge gap that this project will address. The project will investigate how agroecological management practices influence resilience to multiple stresses in wheat and pea. You will examine how management practices modify genotype responses across growing conditions, with a particular focus on interactions between genotype, environment, and management. The aim is to understand how management practices shape resilience to multiple stresses in different crop genotypes and to identify promising variety–management combinations that support stable performance under low-input conditions. Experiments will be conducted under field conditions, comparing different agroecological management practices. Measurements will include crop development, phenology, yield, and quality traits, alongside monitoring of a broad range of abiotic and biotic stresses, including drought, heat, nutrient limitation, weeds, pests, and diseases. Biodiversity assessments, microbiome analyses, and environmental observations will provide additional context for evaluating the wider effects of management practices and for interpreting crop performance under field conditions. As the PhD student in this project, you will gain broad research experience through field experimentation, data processing, statistical analysis, scientific writing, and the communication of research findings. You will work closely with researchers at SLU and with partners in a European research consortium. This collaboration will provide excellent opportunities to develop your scientific expertise, build an international research network, and contribute to research across countries and disciplines Qualifications A second-cycle (MSc) degree in agronomy, crop science, plant biology, ecology, plant breeding, agricultural systems science or a related field Documented experience of working with plants, crops, or agricultural systems Good knowledge of plant ecology and an understanding of its relevance to sustainable crop production, agroecological management, or crop resilience Documented experience in statistical data analysis Good command of written and spoken English The following qualifications would be an advantage: Documented experience with crop phenotyping, crop physiology, or genotype evaluation Documented experience with field assessment of weeds, pests, diseases, or environmental factors Documented experience in scientific writing and communication A driver's license valid for use in Sweden We place particular emphasis on personal qualities.

Human Exposure to Emerging Environmental Contaminants via High-Resolution MS
Department of Water and Environment Doctoral Study Subject: Environmental Analysis with specialization in Environmental Chemistry Description of the Doctoral Project: This doctoral project aims to develop an analytically robust strategy to identify, measure, and interpret emerging environmental contaminants (contaminants of emerging concern, CECs) relevant to human exposure via water. The project will use existing information from pan-European monitoring campaigns stored in the NORMAN database on chemical occurrences to identify substances that may be present in water resources and contribute to human exposure. Based on this knowledge, the doctoral student will develop and validate analytical methods for selected emerging contaminants and apply these to water-related samples collected at the national or international level. The results will be interpreted using hazard, exposure, and risk indicators to support the prioritization of substances for future monitoring. Additionally, suspect screening and non-target screening will be used to identify new substances that can contribute to early warning systems for emerging chemical risks. The project includes: i) selection and prioritization of emerging environmental contaminants using European monitoring data and information on chemical properties of substances; ii) development and validation of an LC-HRMS-based targeted method for selected substances; iii) application of the method to water-related samples, such as drinking water and precipitation; iv) comparison between LC-HRMS and LC-MS/MS for selected compounds to evaluate sensitivity, linearity, precision, and suitability for monitoring; and v) interpretation of results in relation to human exposure. You will work in an international and interdisciplinary research team. The project provides access to advanced instrumentation and training in data analysis, scientific communication, and international research collaboration. Duties: We are seeking a doctoral student who wants to contribute to increased knowledge of emerging environmental contaminants in water-related exposure pathways for humans, with a particular focus on analytical method development and high-resolution mass spectrometry. To achieve this goal, you will develop and apply analytical workflows for determining selected emerging contaminants in water-related samples collected at the national or international level. The selection of substances will be based on existing knowledge and available monitoring data. A central part of the project is the use of liquid chromatography coupled to high-resolution mass spectrometry (LC-HRMS) for sensitive and reliable chemical analysis. Analysis of polar substances may require the use of specialized chromatographic columns. The project may also include comparisons between LC-HRMS and LC-MS/MS for selected substances to assess method sensitivity, linearity, precision, and suitability for monitoring. Selected samples may be analyzed using effect-directed analysis (EDA) to link chemical occurrence to biological effects. Duties also include sample preparation, extraction and analysis of contaminants, HRMS data processing, quality assurance, data analysis, visualization and interpretation of results using hazard, exposure, and risk indicators, collaboration with national and international partners, and authoring scientific articles in English. Eligibility: Basic eligibility is held by those who have completed an advanced degree, completed course requirements of at least 240 ECTS credits, of which at least 60 ECTS at the advanced level, or who have otherwise acquired substantially equivalent knowledge within or outside the country (the Higher Education Ordinance, Chapter 7 § 39). Special eligibility for admission to doctoral studies in the subject of Environmental Analysis with specialization in Environmental Chemistry is held by those with knowledge in aquatic ecology, aquatic biogeochemistry, statistics, or ecotoxicology. Undergraduate education must include an independent project. In addition, you must have English language skills equivalent to a passing grade in English B/6 from Swedish upper secondary school. Your Background: Applicants should have a master's degree in analytical chemistry, environmental chemistry, environmental science, toxicology, or equivalent. Specialization in chemical analysis of water pollutants and experience with LC-MS or LC-HRMS are advantageous. Previous experience with laboratory work, sample preparation, extraction and analysis of organic contaminants is beneficial. Experience with method development, method validation, quality assurance, or analysis of water-related matrices is also considered advantageous. Experience with suspect screening and non-target screening workflows is particularly desirable. Skills in data processing using statistical computing and visualization tools (e.g., R, Python, or equivalent) are also advantageous. The ability to handle large analytical datasets and work in a structured and reproducible manner is important for the project. Great emphasis will also be placed on personal qualities such as good collaboration skills, analytical ability and problem-solving skills, accuracy, motivation, and the ability to work both independently and in collaboration with others.
