Complex Fluids Soft Solids
What we do
We describe processes at the nano and micron scales that arise in complex fluids & soft solids. This work is usually driven by as yet unexplained experimental results whose fundamental origin we clarify by developing mathematical and computational models; we also invent new physical effects not yet met in experiment.
Current directions are in active matter for materials, the life sciences and energy, including ion electrokinetics and unconventional effects in odd viscous liquids.

In 2021, I was awarded a 4-year, 56-course interdisciplinary degree in the Humanities (Ethics, Philosophy, History,...) from the University of Athens. This was accompanied by a career break (2016-2021). Earlier, I spent most of my time investigating various areas of science and mathematics.
