Wageningen University & Research is advertising two openings in Printing of Complex Fluids : a PhD and a Postdoc in the chair group Physical Chemistry and Soft Matter / Physics of Soft Matter . The research focuses on the hydrodynamics of complex multicomponent fluids during inkjet printing and droplet formation at very high speeds. Topics include soft matter , physical chemistry , fluid dynamics , microscopy , high-speed imaging , colloids , surfactants , polymers , and model ink systems. The PhD project aims to build a quantitative understanding of jetting behavior, satellite droplets, cavitation, and meniscus dynamics. The postdoc project is more instrument-focused and includes designing and building a high-speed imaging instrument coupled to a fluorescent light sheet microscope, plus bespoke colloidal particles and surfactant molecules for extreme time/length-scale imaging. Supervision is by Prof. Jasper van der Gucht , with dr. Uddalok Sen and dr. Thomas Kodger involved in co-supervision/support. The post is shared by Uddalok Sen , Assistant Professor at WUR. PhD eligibility: completed MSc in physics, physical chemistry, fluid dynamics, or soft matter; independent working style; interest in new instrumentation; experience with soft materials and computational tools; microscopy/high-speed imaging experience; English at C1 level. Postdoc eligibility: PhD in experimental soft matter, physics, fluid dynamics, or a related field; experience developing microscopy/imaging techniques, especially high-speed methods; independent working style; interest in new instrumentation; experience with soft materials; English at C1 level. Funding: the PhD is fully funded. The postdoc is a salaried research position with a gross monthly salary of about €3,546–€5,538 (full-time, 38 hours/week), plus standard WUR employment benefits. The PhD also includes a tailored course program. Deadline: applications are open until 2026-05-15 . Only applications submitted through the WUR website will be considered. For the PhD, applicants should submit a CV and motivation letter (max 3 pages total); additional files such as grades/transcripts are not required at this stage.
