Who is John A. Quinn?

John A. Quinn, Ph.D. is the Robert D. Bent Professor Emeritus of Chemical and Biomolecular Engineering at the University of Pennsylvania School of Engineering and Applied Science. He has been a leader in the fields of mass transfer and membrane transport in synthetic membranes since the 1960s. In the early phase of his career at the University of Illinois, Quinn and his students devised simple, elegant experiments to elucidate the role of the interface in mass transfer between phases. In later work at Penn, he applied these insights to problems of engineering and biological significance involving chemical reaction and diffusion within and through both finely porous and reactive membranes. His chemical engineering science has informed matters as far afield as the separation of chiral pharmaceuticals and the behavior of cells at interfaces.
