Shared Postdoc Position


In the CorwinLab our research is driven by an attempt to understand how complex collective behavior arises in the field of soft-matter physics from the simple interactions of simple components. To this end, our research efforts focus extensively on experimental, numerical, and theoretical studies of the jamming and glass transition(s), the collective behavior of granular materials, complex macroscopic systems subject to chaotic forcing, and the extremes of statistical mechanics.

Visiting Artist Program

The Corwin lab runs a visiting artist program which aims to tell the story of science and scientists from the inside out. Artists are embedded into the Corwin Physics Lab for a period of time where s/he functions side-by-side with research scientists, participating in every aspect of life in the lab. Working alongside researchers in the same space, the artist creates work that responds to the world of science as it is, in all of its complexity and humanity.
