How Things Bend and Break: Materials Science at the Molecular Scale (G,S)
Modeling Smectic Liquid Crystals from the Nanoscale to the Macroscale (G,S)

Robin Selinger received her bachelors and Ph.D. degrees in physics at Harvard University. After postdoctoral work at the University of California at Los Angeles, the University of Maryland and NIST, she joined the physics faculty of Catholic University in Washington, DC. Her research involves applications of statistical physics in computational materials science (fracture, plasticity) and in chemical physics (complex fluids) with a strong emphasis on computer simulation. Her work is funded by the Navy and by the National Science Foundation. Her honors include: the National Science Foundation Career Award, National Research Council Postdoctoral fellowship, the Harvard University Physics Department Robbins Prize, and a Zonta International Amelia Earhart fellowship. Dr. Selinger is a member of the American Physical Society and the Materials Research Society.

Physics of Fluid Thin Films (P)
Fluid Flows in Freely Suspended Films (G)
Hydrodynamics and Turbulence in Two Dimensions (S)

Xiao-Lun Wu received his Ph.D. from Cornell University in physics and is an associate professor at the University of Pittsburgh. His research focuses on the long-standing problem of the effect of spatial disorder on critical fluctuations of Ising-like systems, particularly fluid flow and turbulence in thin, free-standing liquid films as well as particle diffusion and thermal convection. Some of his recent research includes: hydrodynamics in free-standing liquid films, nucleation and chiral symmetry breaking under hydrodynamic flows, structure and dynamics in a glass forming system, internal modes of macromolecules and critical fluctuations in porous media. Dr. Wu has been an invited speaker at Los Alamos National Laboratory, the Aspen Center for Physics, Ford Motor Company and numerous universities and society meetings. He is a member of the American Physical Society and the Materials Research Society.

Spectroscopy and Imaging of Tissues with Diffusing Light (G)
Entropy in Suspension (G)

Arjun Yodh is professor of physics and astronomy and professor of radiation oncology at the University of Pennsylvania. He received his Ph.D. from Harvard University. His current interests involve aspects of chemical, solid-state, and optical physics, with experiments oriented towards lasers and the unique spectroscopies these tools offer (including tissue diagnostics). He elucidated the phenomenology associated with diffusive waves and has shown that diffusing photons can be used to probe variations of the absorption, fluorescence, scattering and dynamical properties of turbid media. His lab group has several areas of ongoing research including: complex fluids, laser spectroscopy of biological samples, biomedical applications of NIR imaging, and non-linear optical spectroscopy. He was an Alfred P. Sloan Research Fellow and a National Science Foundation Presidential Young Investigator, as well as an AT&T Bell Laboratories Faculty Fellow. Currently Dr. Yodh is the William Smith Term Chair at the University of Pennsylvania.
