From the Brownian movements of inanimate matter to the swimming motility of bacteria, the world at the micron scale is extremely dynamic. We are interested in the origins, the consequences and the applications of these motions. To study that, we build digital microscopes that integrate optical and computer hardware and where light can be used for imaging, manipulation and fabrication of microsystems in 3D.
