About me


M.Phys Master of Physics: Investigating self-assembly phenomena in the drying of bimodal
colloidal films


I am a physicist focused on colloids, rheology, and soft matter physics more generally. These
fields combine knowledge of nano and microscale phenomena to paint our understanding of
the forces and interactions that describe fascinating phenomena ranging from the colloidal
nature of cells and proteins in our blood to those that give rise to the unusual behaviour of
non-newtonian fluids under stress. As an experimentalist, I really enjoy being able to test these
phenomena down to the nanoscale and directly observe the dynamics that drive them.
Key words: Experimental physics, Colloid science, Rheology, Flow Phenomena


About my PhD research
Subject: Restructuring colloidal gels through ultrasound-activated deformable inclusions
Research description: Colloidal gels consist of a structural network of particles that give rise
to their rheological properties. In these systems, ultrasound-induced bubble oscillations have
been found to alter the nearby microstructure of particles, making the local tailoring of
rheological properties possible. I will conduct experimental research to uncover the underlying
flow mechanisms that drive this effect, with the goal of bridging the gap between tailoring and
precise control over the microstructure of colloidal gels. Ultimately, this project aims to deepen
our fundamental knowledge of colloidal gels and uncover applications for the development of
new products.
