Lynn Walker is a professor in the Department of Chemical Engineering at Carnegie Mellon University, with courtesy appointments in the Departments of Chemistry and Materials Science & Engineering. Walker received her B.S. Chemical Engineering degree from the University of New Hampshire in 1990 and her Ph.D. from the University of Delaware in 1995, under the supervision of Norman Wagner. After holding a postdoctoral position at Katholieke Universiteit Leuven, Leuven Belgium, Walker joined Carnegie Mellon’s Department of Chemical Engineering in 1997. Walker was a visiting professor during a sabbatical at Polymer IRC, University of Leeds in 2007.

Research in the Complex Fluids Rheology group focuses on understanding and controlling complex, or structured, fluids in engineering applications. Walker’s group’s work is primarily experimental and involves rheometric characterization, classical colloid and macromolecular analytical techniques, small-angle scatterning and microfluidic tools. They collaborate closely with others in the Center for Complex Fluids Engineering. Two main themes, Impact of Nanoscale Structure on Rheology and Behavior of Complex Systems with Fluid-Fluid Interfaces, run through the group and their interests lie in applying fundamental knowledge and ideas to real engineering situations.
