Sela Samin

This page collects my work as a scientist trying to make sense of soft and complex systems. Most of the work was done between 2014 and 2018, when I was a post-doc in the group of Prof. René van Roij at the Institute for Theoretical Physics, Utrecht University.

My research focuses on theoretical studies at the interface of soft condensed matter and fluid mechanics. My scientific interests include multi-phase transport at small scales, active colloids, electrostatics and fluid dynamics in porous materials, and suspensions of charged and magnetic colloids.
