Seth Fraden

seth fradenProfessor of Physics
Ph.D., Brandeis University, 1987

Our group studies a broad range of topics in Soft Matter. We utilize a variety of methods and approaches covering experiment, theory, and simulation. Our research interests lie squarely in the intersection of physics, chemistry, biology and materials science. Our lab is interdisciplinary, but we are also involved in several multi-investigator projects. Current areas of interest are active matter, coupled non-linear chemical oscillators, protein crystallization, microfluidics, colloidal liquid crystals, DNA - colloid self-assembly and DNA origami.
