David A. Weitz

Mallinckrodt Professor of Physics and Applied Physics. Experimentalist in the field of soft-condensed matter physics, known for explorations of colloids, foams, gels, glasses, biological rigidity and the cellular cytoskeleton, and emulsions; creating novel materials; and showing how macroscopic properties can be understood microscopically. Developed and used powerful methods for studies of soft materials, including microrheology, microfluidics, confocal microscopy, and diffusing wave spectroscopy. Carried out definitive set of experiments on emulsion droplets with colloidal particles that led to advancements in the field of colloid stabilized (Pickering) emulsions. Serves as director or co-director of three materials science research centers.
