Randall David Kamien 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 is the son of economist Morton Kamien and his wife Lenore. ^[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 Physical Society and the American Association for the Advancement of Science. ^[4] Kamien was the chief 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."
