Amélie Chardac

Physicist interested in soft and active condensed matter.

I am currently a postdoc in the group of Guillaume Duclos, at Brandeis University (Waltham, MA, USA).

I am a soft condensed matter physicist interested in pattern formation and collective behavior. I perform experiments and analyze data in order to investigate how topological defects and external fields affect self-organization in active systems.

My current research interests include emergence of collective motion, pattern formation, control of active fluids and frustration of topological active materials. I perform experiments using biomimetic systems made of purified proteins and networks of molecular motors and microtubules.

My PhD work @BartoloLab (ENS de Lyon, France) consisted in understanding the marvelous phases of polar active matter. My main goals were to investigate the robustness of colloidal flocks in disordered media, and the coarsening dynamics of active fluids. I addressed these questions by performing and analyzing experiments based on self-propelled colloids that spontaneously organize into a flock at high density (Quincke rollers).

I am also interested in education and outreach. I am currently a Fellow in the SciComm Lab at Brandeis, where I help scientists to improve their Science Communications skills. Some materials I made to distribute my research to a broad audience are available in the Outreach & Science communication tab.
