Abstract: Within the last 20 years, the use of microscopy to visualize DNA chains in flow as pioneered by Chu and co-workers has revolutionized our understanding the fluid flows of long chain hydrocarbons or “polymers”. These flows are critical to the processing of plastics for molded parts, coatings, and even food. Rather than simply postulating models for polymers in various ``strong'' flow fields (i.e. those that create significant molecular deformation), researchers can now directly examine the conformational statistics of a molecule in flow far from equilibrium. Combining these experimental studies with computational molecular models, researchers have an extremely powerful tool to probe the physics in the molecular dynamics.

In this presentation, I will review the state of research in single DNA dynamics studies in flow including a variety of important flow fields and I will discuss outstanding questions that have developed in this research. I will also introduce and discuss a few relatively new applications of single molecule microscopy involving DNA dynamics in micro-post arrays, as scaffolds for molecular wires and in non-dilute solution. All of these examples indicate that the applications of examining polymer dynamics “one molecule at a time” are burgeoning and will play an important role in the study of polymeric liquids in the foreseeable future.

Biographical information: Eric Shaqfeh is the Lester Levi Carter Professor and Department Chair of Chemical Engineering at Stanford University. He joined Stanford’s faculty in 1990 after earning a B.S.E. summa cum laude from Princeton University (1981), and a M.S. (1982) and Ph.D. (1986) from Stanford University. In 2001 he received a dual appointment and became Professor of Mechanical Engineering. He is most recently (as of 2004) a faculty member in the Institute of Computational and Mathematical Engineering at Stanford.

Shaqfeh’s current research interests include non-Newtonian fluid mechanics (especially in the area of elastic instabilities, and turbulent drag reduction), nonequilibrium polymer statistical dynamics (focusing on single molecules studies of DNA), and suspension mechanics (particularly of fiber suspensions and particles/vesicles in microfluidics). He has authored or co-authored over 170 publications and has been an Associate Editor of the Physics of Fluids since 2006.

Shaqfeh has received the APS Francois N. Frenkiel Award 1989, the NSF Presidential Young Investigator Award 1990, the David and Lucile Packard Fellowship in Science and Engineering 1991, the Camile and Henry Dreyfus Teacher--Scholar Award 1994, the W.M. Keck Foundation Engineering Teaching Excellence Award 1994, the 1998 ASEE Curtis W. McGraw Award, and the 2011 Bingham Medal from the Society of Rheology. A Fellow of the American Physical Society, he has held a number of professional lectureships, most recently the Merck Distinguished Lectureship, Rutgers (2003), the Corrsin Lectureship, Johns Hopkins (2003) and the Katz Lectureship, CCNY (2004). He was also the Hougen Professor of Chemical Engineering at the University of Wisconsin (2004) and the Probstein Lecturer at MIT (2011).
