SMatCH  |  Soft Materials Coffee Hour

What is SMatCH?
Princeton has an amazing community of researchers whose work deals with soft materials: liquids, polymers, foams, gels, colloids, granular materials, as well as most soft biological materials. This is an opportunity for us all to come together!

Nothing formal: simply a venue to meet other people with mutual interests over cookies-free thanks to support by PRISM, coffee (free!), and talk about research or anything else. We usually have two or three mini-talks each less than 10 min long followed by general mingling and discussion.
