Paul Nealey is a pioneer of directed self-assembly, which is becoming very important in microelectronics processing to create patterns for integrated circuits. He is one of the world’s leading experts on patterning organic materials, literally creating physical patterns of structure and composition in the materials at the nanometer length scale, where the patterns affect the function of the materials.
Many of Prof. Nealey’s collaborative projects with Prof. Juan de Pablo have focused on block copolymer films, which spontaneously self-assemble to form structures with dimensions that range from three to 50 nanometers. Nealey’s experimental and de Pablo’s computational teamwork extends even to jointly advised doctoral students. Their approach has become so powerfully productive that other institutions seek to replicate their formula for success with their own research teams.
Nealey’s interest in tissue engineering of corneal prosthetic devices, pursued in collaboration with a veterinary ophthalmologist, demonstrates the versatility of his expertise in fabricating nanostructured surfaces.
Nealey holds 14 patents and is the author of more than 180 publications. His honors include fellowship in the American Physical Society, the 2010 Nanoscale Science and Engineering Forum Award from the American Institute of Chemical Engineers, and a 2009 Inventor Recognition Award from Semiconductor Research Corporation.
Prior to arriving at the Pritzker School of Molecular Engineering, Nealey was Shoemaker Professor of Chemical and Biological Engineering, University of Wisconsin–Madison. He also conducted postdoctoral research at Harvard University and was an engineer at Solvay et Compagnie, Brussels.
Nealey earned a PhD in chemical engineering from the Massachusetts Institute of Technology. He holds a BChE, magna cum laude, from Rice University.
The Nealey Group consists of graduate students and postdoctoral researchers pursuing interdisciplinary topics in advanced lithography, nanofabrication, polymer thin films, and cell-substrate interactions.
