Single particle motion in colloids:  Microrheology and microdiffusivity

Professor John F. Brady received his BS in chemical engineering from the University of Pennsylvania in 1975 and spent the next year at Cambridge University as a Churchill Scholar. He received both an MS and a PhD in chemical engineering from Stanford University, the latter in 1981. Following a postdoctoral year at the Ecole Superiéure de Physique et de Chimie Industrielles, he joined the Chemical Engineering department at MIT. Professor Brady moved to Caltech in 1985. Professor Brady's research interests are in the mechanical and transport properties of two-phase materials, especially complex fluids such as biological liquids, colloid dispersions, suspensions, and porous media. His research takes a multilevel approach and combines elements of statistical and continuum mechanics to understand how macroscopic behavior emerges from microscale physics. He is particularly noted for the invention of the Stokesian Dynamics technique for simulating the behavior of particles dispersed in a viscous fluid under a wide range of conditions. Professor Brady has been recognized for his work by many awards, including a Presidential Young Investigator Award, a Camille and Henry Dreyfus Teacher-Scholar Award, the ASEE Curtis W. McGraw Research Award, and the Corrsin and Batchelor lectureships in fluid mechanics. He is a fellow of the American Physical Society and a member of the National Academy of Engineering.

Elastic instabilities in entry flows: A consequence of upstream stretch or downstream relaxation? (Click here for abstract)

Professor Justin Cooper-White received his PhD at the University of Queensland in 2000. His research interests are in biomaterials processing, tissue engineering, non-Newtonian fluid mechanics, rheology and microfluidics. Specifically, his research group at the Tissue Engineering and Microfluidics (TEAM) Laboratory has projects in all of these areas with a common focus of providing fundamental insight into complex polymer-based structures and systems, with the aim of ultimately tailoring and controlling their interactions with biological systems. These projects are investigating novel methods of manufacturing polymeric scaffolds and methods of surface engineering of these scaffolds for drug delivery and tissue engineering applications, new in vitro modules for mapping cell-surface and cell-scaffold interactions, manufacturing functional microparticles with micro processing plants and complex fluid behaviour in microdevices.

Linear and nonlinear rheology of entangled, flexible polymers that are highly branched (Click here for abstract)

Professor Gary Leal is Warren and Katherine Schlinger Professor of Chemical Engineering and Chair of the Department of Chemical Engineering at the University of California, Santa Barbara where he conducts research on the dynamics of complex fluids, such as polymeric liquids, emulsions, foams, polymer blends, and liquid crystalline polymers (LCPs). Much of this is related to the coupling between the influence of flow on the microstructure of these materials, and hence on the macroscopic material properties. Within this broad framework, Professor Leal is working on: coalescence phenomena; the dynamics of thin liquid films and the control of the stability of such films due to additives such as copolymer surfactants, and nano- or micro-particles; the flow behavior of LCPs, including the formation of disclinations; and the dynamics of entangled polymers. Professor Leal is the recipient of the American Physical Society Fluid Dynamics prize, the Society of Rheology Bingham medal and the AIChE Allan Colburn award; he is currently the editor of Physics of Fluids and is the John Simon Guggenheim Foundation Fellow, Fellow of the American Physical Society and a member of the National Academy of Engineering.
