Microfluidics Adventures #1: Physics at the microscale

$How to make a miniature river What if we recreated rivers in the lab, to better understand them in real life? 🏞️ This the PhD work of Anaïs Abramian! She takes us on a tour of this model experiment, at the crossroads between physics and geology! ↓ More infos and links in the description! ↓ LINKS: French version: https://www.youtube.com/watch?v=yY76LOO4P0E Subscribe to the channel : https://youtube.com/thelutetiumproject Follow us on Twitter : https://twitter.com/TheLuProject Visit our website: https://www.lutetium.paris/en MORE ABOUT THE INTERVIEWEE: Anaïs Abramian is an alumna of ENS Lyon. She obtained a masters degree in liquid state physics from École Normale Supérieure. She conducted her PhD thesis at Institut de Physique du Globe de Paris, as a member of the team of Geological Fluid Dynamics. She defended in 2018; her thesis was titled Self-organisation of sediment transport in alluvial rivers. She then joined Institut Jean le Rond dAlembert as a postdoctoral researcher in 2019. Her research now focuses on cohesive granular materials.
