The overarching project investigates how plant cells rapidly integrate co-occurring osmotic, salinity and pathogen-derived signals. Your PhD project will examine B4-RAF protein kinases as intracellular signal integrators. These kinases are activated rapidly by diverse environmental stimuli and occur in distinct subcellular puncta, suggesting that they assemble into signalling complexes (signalosomes) that coordinate early cellular responses.

You will (1) identify and validate the components of B4-RAF signalling complexes in Arabidopsis thaliana, (2) establish how these complexes assemble and localize under distinct environmental conditions, and (3) determine how these complexes contribute to stress resilience. The work combines plant molecular biology, protein biochemistry, functional proteomics, quantitative live-cell imaging and genetics.

Core research activities include:

• identify candidate B4-RAF signalosome components through immunoprecipitation coupled to tandem mass spectrometry (IP–MS/MS), building on existing proximity-labelling datasets;
• validate protein interactions and co-localisation using approaches such as FRET-FLIM, co-immunoprecipitation and live-cell confocal imaging;
• generate and characterise Arabidopsis loss-of-function and fluorescent reporter lines;
• use microfluidics-coupled live-cell imaging to investigate the spatiotemporal dynamics, environmental conditionality and subcellular localisation of B4-RAF signalling complexes;
• integrate proteomics, imaging and genetic datasets to develop mechanistic models of rapid plant signal integration.

Tasks and responsibilities:

• complete a PhD thesis within the official appointment duration (four years);
• systematically and independently design, perform, analyse and document experiments;
• be an active and responsible member of the research group
• collaborate closely with other group members (incl. PhD candidate, technicians and postdoc);
• discuss work with group members and at departmental meetings, and incorporate feedback;
• take a leading role in writing manuscripts for publication in peer-reviewed journals;
• participate in the PhD training programme of the University of Amsterdam and the national graduate school Experimental Plant Sciences (EPS);
• assist with teaching and supervision of Bachelor’s and Master’s students.

You will have the opportunity to:

• work at the interface of plant genetics, biochemistry, functional proteomics and quantitative imaging;
• present results at national and international scientific conferences;
• expand academic, professional and personal skills;
• contribute to science communication and outreach activities;
• thrive in a team that values impactful research and mutual support;
• combine the advantages that a collaborative project offers, including access to state-of-the-art research facilities at the Swammerdam Institute and the University of Amsterdam.

You are passionate about science and have a particular interest in biochemistry and cell biology. You are eager to understanding complex environmental signalling mechanisms in plants at the molecular level and have a strong interest in protein signalling mechanisms, especially kinase regulation, protein complexes or phosphorylation-dependent signalling. You enjoy combining experimental biochemistry with molecular genetics and quantitative microscopy. You are methodical, curious and able to take initiative, while also valuing close collaboration in an interdisciplinary and international research environment.

Your experience:

• an MSc degree in molecular biology, biochemistry, or a closely related discipline.
• demonstrated hands-on laboratory experience in at least two of the following areas: protein biochemistry, (plant) molecular biology, confocal microscopy, proteomics and protein-protein interaction assays;
• ability to plan experiments carefully, maintain high-quality laboratory records, analyse results critically and troubleshoot experimental work;
• fluent in English, both written and spoken;
• ability to work independently as well as constructively in an international team.

Experience with CRISPR/Cas9 genome editing in plants or analysis of proteomics and/or imaging data (e.g. using Python or R) is a plus.

A temporary contract for 38 hours per week for the duration of 4 years (the initial contract will be for a period of 18 months and after satisfactory evaluation it will be extended for a total duration of 4 years). The preferred starting date is not later than February 1st, 2026. This should lead to a dissertation (PhD thesis). We will draft an educational plan that includes attendance of courses and (international) meetings. We also expect you to assist in teaching undergraduates and master students.

Your salary will range between €3,204 in the first year to €4,051 gross per month in the last year of employment, based on a fulltime employment (38 hours per week). This sum does not include the 8% holiday pay and the 8.3% end-of-year bonus. A favorable tax agreement, the 30% ruling, may apply to non-Dutch applicants. The Collective Labour Agreement for Dutch Universities (CAO NU) is applicable.

Besides the salary and a vibrant and challenging environment at Amsterdam Science Park we offer you multiple fringe benefits:

• 232 holiday hours per year (based on fulltime);
• multiple courses to follow from our Teaching and Learning Centre;
• a complete educational program for PhD students;
• a pension at ABP for which UvA pays two third part of the contribution;
• the possibility to follow courses to learn Dutch;
• help with housing for a studio or small apartment when you’re moving from abroad.
