PhD in Biomedical Engineering: Dynamic Interaction Forces and Their Use in Biomedical Technologies

The laboratory of Prof. Xavier Banquy at the University of Montreal is recruiting a motivated PhD candidate to study interaction forces between biomimetic surfaces at the nanoscale. The project aims to move beyond static models by exploring how external fields, such as electric and acoustic stimuli, dynamically reprogram force–distance relationships and binding kinetics in real time. Two main research tracks are offered: Track 1 focuses on electro-stimulation in weak electrolytes, where AC electric fields are used to polarize interfaces and drive induced-charge electro-osmosis, enabling rapid reorganization of ion clouds and dynamic control of double-layer repulsion and ligand–receptor interactions. Track 2 investigates acoustic actuation in nanogaps, using high-frequency vibrations to generate squeeze-film pressures and acoustic streaming, thereby modulating hydrodynamic drainage and the balance of dispersion, hydration, and electrostatic forces. The project leverages advanced force spectroscopy and imaging techniques to map the coupling between ion transport, micro-fluid dynamics, and interfacial energetics, revealing field-responsive changes that are not apparent in equilibrium models. These insights are expected to directly inform the development of new biomedical technologies, including improved drug administration, penetration, pharmacokinetics, and dynamic control of tissue–device interfaces. The PhD program offers comprehensive training at the intersection of physical chemistry, soft matter, and bioengineering, making it ideal for ambitious students interested in translating fundamental discoveries into real-world biomedical applications. The Banquy laboratory is located on the main campus of the University of Montreal, in the vibrant city of Montreal, which is recognized as a top destination for graduate studies. The lab provides world-class research facilities and a stimulating environment for students pursuing careers in materials engineering and related fields. Federal funding (Canada Research Chair) is secured for the full four-year duration of the PhD. Applicants should have prior experimental research experience, preferably in materials mechanics, nanotechnology, biomaterials, surface characterization, or force measurements, and must be highly motivated, proficient in English, and eager to work in a multidisciplinary setting. To apply, candidates should send their transcripts, cover letter, CV, and references to Prof. Banquy.
