Saville Lectures

Dudley A. Saville
Dudley A. Saville

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.

2014 Saville Lecturer: Ryan C. Hayward

Ryan Hayward is an Associate Professor of Polymer Science and Engineering at the University of Massachusetts Amherst. He received a B.S.E. in Chemical Engineering in 1999 from Princeton University, where he conducted research with William Graessley on solution-state properties of polymers, and with Dudley Saville and Ilhan Aksay on electrophoretic assembly of colloids.  At the University of California, Santa Barbara he worked with Edward Kramer and Bradley Chmelka on block copolymer templating of inorganic materials and received his Ph.D. in Chemical Engineering in 2004. From 2004-2005 he worked with David Weitz in Engineering and Applied Sciences at Harvard University as a post-doctoral fellow, on microfluidic emulsion processing. His group studies a variety of topics in polymers and soft materials, with a particular focus on thin films and interfaces. Recent areas of interest include swelling-induced deformation of constrained and micro-patterned stimuli-responsive gels, and solution state self-assembly of polymer and particle-based nanostructures. His honors and awards include the Presidential Early Career Award for Scientists and Engineers (PECASE), the 2011 ACS Division of Colloid and Surface Chemistry Unilever Award, the 2013 Journal of Polymer Science Innovation Award, and the 2014 John H. Dillon Medal of the American Physical Society. Since 2013, he has served as an Associate Editor for the journal ACS Macro Letters.


Tuning Interactions and Self-assembled Structures in Polymer Heterojunctions and Nanocomposites

The Hayward Group seeks to take advantage of supramolecular interactions between polymers, nanoparticles, and small molecules to precisely control the self-assembled morphologies, and resulting properties, of multi-component mixtures. In one example, we consider assembly of conjugated polymers, where the interactions between p -conjugated systems are central to both self-assembly and electronic conductivity. We have studied polythiophenes as a basis for the controlled growth of hybrid nanowire structures, and as crystal modifiers to tailor the growth of electron accepting materials such as perylene diimides. In a second example, we take advantage of hydrogen bonding interactions between ligand and matrix polymer chains to tailor dispersion of grafted nanoparticles in polymer matrices. Favorable interactions yield dispersion even when entropic considerations would lead to aggregation of athermal systems, and the temperature-sensitivity of hydrogen bonds provides opportunities for the design of materials with tailored and switchable dispersion states.
