Seminar 11/9/2011 - Marjorie Longo, UC Davis: Engineering & Patterning of Domains in Lipid Assemblies: From Wine-making to Membrane 'Circuits'

Abstract: The compositional flexibility and self-assembling nature of lipid assemblies makes them very attractive platforms for study and engineering. I will briefly introduce a few examples from our lab involving experimental models for: membranes of wine yeasts, lipid shells of medical microbubbles, obstacles for diffusion, and curvature sorting of lipids. I will present new results where we use nanofabricated substrates that impose curvature to create dynamic sorting patterns of lipid domains that resemble the pixilated patterns of integrated circuits.

Bio: Marjorie (Margie) Longo is a Professor of Chemical Engineering and Materials Science at UC Davis, where she has been since 1996. She received her bachelors and PhD degrees from the University of California, Santa Barbara in Biochemistry and Chemical Engineering, respectively.  Her postdoctoral work was performed at Cornell University, Ithaca, New York. Professor Longo's research employs, develops, and combines quantitative microscopy techniques to gain knowledge of the structure, transport, thermodynamics, and mechanics of synthetic lipid bilayer membrane and monolayer systems. These serve as models of real biological membranes, and in some cases have technological applications that are easily identified (e.g. drug delivery devices). Recently she received the UC Davis Engineering Dean's Outstanding Mid-career Research Award.

All seminars are held on Wednesdays from 12:00 noon-1:00 p.m. in the Bowen Hall Auditorium Room 222. A light lunch is provided at 11:30 a.m. in the Bowen Hall Atrium immediately prior to the seminar.
