Chemical and Biological Engineering

In memory of our colleague, Princeton University’s Department of Chemical Engineering has established the Dudley A. Saville Lectureship for exceptional early-career chemical engineers and scientists. Inspired by his family and colleagues, this series reflects Dudley Saville’s longtime association with Princeton, his uncompromising pursuit of excellence, and his commitment to helping young people begin their academic careers. In his nearly 40 years at Princeton University, he pioneered new directions in fluid mechanics, especially electrohydrodynamics. Although Dudley’s emphasis was always on fundamentals, the practical applications of his research spanned protein crystallization, electrohydrodynamic printing, enhanced oil recovery, patterning of colloidal crystals, and fluid behavior in microgravity, including an experiment flown on the Space Shuttle Columbia.

Dudley was also a pillar supporting the department’s educational mission. Whether teaching thermodynamics, fluid mechanics, engineering mathematics, or transport phenomena, his classes were distinguished by their mathematical rigor and clarity of exposition. A demanding instructor, he earned the respect of generations of chemical engineering students.

In 1997, he received the Alpha Chi Sigma Award from the American Institute of Chemical Engineers; in 2001, he was named the Stephen C. Macaleer ’63 Professor in Engineering and Applied Science; and in 2003 he was elected to the National Academy of Engineering, the highest professional recognition for an American engineer.

Todd Squires earned dual B.S./B.A. degrees in Physics and Russian Literature at UCLA in 1995, then spent a year as a Churchill Scholar at Cambridge University, where he earned a distinction in Part III of the mathematics tripos in DAMTP. He earned his Ph.D. in Physics from Harvard University in 2005 under the supervision of Michael Brenner and Howard Stone, on problems in colloidal hydrodynamics and electrokinetics. He then spent three years as a Lee A. Dubridge Prize Postdoctoral Fellow and NSF Mathematical Sciences Postdoctoral Fellow at Caltech, where he continued theoretical work in electrokinetics and microfluidics, and initiated new studies of nonlinear microrheology with John Brady.

He is currently associate professor of Chemical Engineering at the University of California, Santa Barbara, where he started his faculty career in 2005. His group focuses on micro-scale fluid mechanics and transport, both experimentally and theoretically. Specific areas of interest include linear, nonlinear and interfacial microrheology, and theoretical, experimental and computational studies of electrokinetics and ion transport for flow manipulation and energy storage. Honors include the NSF CAREER award, the Beckman Young Investigator, and the Camille and Henry Dreyfus Teacher-Scholar award, the Francois Frenkiel Award from the APS Division of Fluid Dynamics, and the 2010 Allan P. Colburn Memorial Lectureship at the University of Delaware.
