Research Area

Soft Matter Physics

Sorensen's research concerns aerosols and colloids. Topics include aggregation kinetics, aggregate morphology and gelation. His experiments often involve light scattering so he also studies the optical properties of particles and their aggregates. In related work he has developed novel synthetic chemical techniques to create nanoparticles of uniform size which form 2d and 2d superlattices.

Sorensen is also interested in curriculum development and has implemented studio instruction into Engineering physics and Optics and integrated primary text readings into Physical World.
