Microfluidic droplet generation. Each droplet is 100 micrometer in diameter

Nucleation of Dextran microdroplets at the edge of a drop under evaporation.

The nucleated microdroplets coalesce and advance in a stepwise manner ((Soft Matter, 2024,20, 8260-8266))

Phase separation of a PEG/dextran microdroplet during evaporation. The nuclei flow inside the droplets and eventually merge to form discrete phases.

This is a sessile drop of PEG and dextran evaporating on a solid surface. The dextran nucleates upon liquid-liquid phase separation and migrates towards the center of the drop. Our study explains how these dynamics evolves over time (Soft Matter, 2024,20, 8260-8266)

Bacteria (Mycobacterium smegmatis) replicate and forms a colony. We study how salt affects their growth and response to antibiotics.
