Timothy P. Lodge

Lodge contributed to the understanding of polymer structure and dynamics. His precise diffusion experiments led to a revision of reptation, the fundamental theory of polymer dynamics. He showed that combining reptation with insight into the universal effect of chain connectivity on local packing (self-concentration) can correctly predict the viscosity of polymer mixtures. He also made discoveries on the dynamics and self-assembly of block copolymers. Lodge developed a systematic route to structured micelles--block copolymer micelles in which the micellar cores are subdivided. This work has been cited over 500 times and led to studies by many other researchers and applications to drug delivery, viscosity modification and nanostructure templating.
