This postdoctoral project at Wageningen University & Research focuses on the physical chemistry behind food ingredient functionality and on improving how it is measured across laboratories. The work addresses a clear methodological challenge in food science: analytical methods for properties such as emulsifying, foaming, and gelling functionality are often not sufficiently standardized, making comparisons between studies difficult. The successful candidate will contribute to the development, cri...

About this position

This fully funded PhD position at Wageningen University & Research focuses on the mechanisms of surface-active chemical (SAC) film formation and their mechanical properties, particularly in the context of recycled cardboard industry and microbial biofilms (anaerobic granular sludge). The project integrates expertise from surface rheology, material science, food physics, and environmental process engineering to investigate how SACs interact with biofilm surfaces, their rheological properties, and the implications for process stability in water treatment. The research aims to identify problematic chemicals, understand their biodegradability and accumulation, and redesign biological processes to avoid instabilities. Key activities include preparation and rheological characterization of SAC films, development of surface rheology protocols, use of colloidal probe atomic force microscopy (AFM) and super resolution microscopy to visualize and quantify film structure, and assessment of mass transfer of biogas through these films using microfluidics.

The project is embedded within the chair of Physics and Physical Chemistry of Foods, led by Prof. Erik van der Linden, and co-supervised by Dr. Dainis Sudmalis, Dr. Mehdi Habibi, and Dr.

Leonard Sagis. Collaboration with industry partners and another PhD project at Environmental Technology is central. Candidates should have an MSc in a relevant field, strong background in rheology, fluid dynamics, or bioprocess engineering, and be fluent in English (C1 level).

Experience with Python, rheology, and AFM is a plus. The position offers a competitive salary, excellent benefits, and a supportive, international research environment.

Applications are open until November 25, 2025, and must include a CV and motivation letter (max 3 pages), plus a mandatory information form. Wageningen University & Research provides assistance for international staff, including visa support and integration services.

What's required

Applicants must hold an MSc degree in physical chemistry, food physics, applied physics or mechanics, material science, chemical engineering, environmental engineering, or biotechnology. Strong background in rheology, fluid dynamics, or bioprocess engineering is required. Candidates must be fluent in written and spoken English at C1 level; an English proficiency certificate is required if the MSc was not obtained in the Netherlands or English is not the mother tongue. Official, stamped MSc degree certificate is required. Good command of programming languages like Python, experience with rheology, and experience with atomic force microscopy (AFM) are considered a plus. Motivation for multidisciplinary work and collaboration is essential.
