Collective behavior of crowded drops in microfluidic systems

In a crowded and confined system where many drops interact, how do the interactions give rise to collective behavior? How do these interactions impact the performance of droplet-based microfluidic technology, and how can we overcome or leverage such interactions? This paper reviews our recent work on answering these questions, by studying the collective behavior of droplets in a concentrated emulsion and tracking the dynamics and the fate of individual droplets within the emulsion in a microfluidic system.
