Randall David Kamien (born February 25, 1966) is a theoretical condensed matter physicist specializing in the physics of liquid crystals and is the Vicki and William Abrams Professor in the Natural Sciences at the University of Pennsylvania.[1]

Biography

Randall Kamien was born to economist Morton Kamien and Lenore Kamien on February 25, 1966, and grew up in Wilmette, Illinois on the outskirts of Chicago.[2] Kamien completed a B.S. and a M.S. in physics at the California Institute of Technology in 1988 and completed a PhD in physics at Harvard University in 1992 under the supervision of David R. Nelson.[3] Prior to joining the faculty at the University of Pennsylvania he was a member of the Institute for Advanced Study in Princeton, New Jersey, and a postdoctoral research associate at the University of Pennsylvania. Kamien was appointed assistant professor at the University of Pennsylvania in 1997 and promoted to full professor in 2003.[4] Kamien is a fellow of the American Physics Society and the American Association for the Advancement of Science.[4] Kamien is the editor of Reviews of Modern Physics.[5]

Research

Randall Kamien studies soft condensed matter – and in particular liquid crystalline phases of matter – through the lens of geometry and topology.[6] In particular, Kamien has contributed to understanding Twist Grain Boundaries,[7] Focal Conic Domains,[8] and defect topology in smectic liquid crystals.[9] He is also known for his idiosyncratic naming conventions, such as “Shnerk’s Surface” [10] and “Shmessel Functions.”
