Women in Science and Engineering Postdoc Networking Group
Fri, Jan 12, 2007 @ 12:00 PM - 01:00 PM
Viterbi School of Engineering Student Affairs
Workshops & Infosessions
A group of post-docs has formed a cross-disciplinary group targeted at Women in Science and Engineering Post-docs. The goal is to provide networking, career, and social opportunities (for example, how to prepare for the academic job market, etc.) for female post-docs at USC. The group has been given seed money by USC's WiSE program and will hold meetings on the second Friday of each month, beginning January 12.For more information including location, please contact Angie Knapp (angelakn@usc.edu) or Katharine Moore (katharim@usc.edu).
Location: To be determined
Audiences: Postdoctoral Scholars / Visiting Scholars

Graduate SeminarProtein Mobility, Filtering, and Separation in Model Cell MembranesDr. Susan Daniel
Department of Chemistry
Texas A&M UniversityAbstract
Investigating how biomolecules behave in cell membranes gives us insight that can be used
to create better assays, sensors, and devices that mimic the cell surface. Applications for
these devices include rapid combinatorial analysis of drug targets, biosensors for toxin
detection, and proteomics research. Solid-supported lipid bilayers (SLBs) are an excellent
platform for mimicking the surface chemistry of cells. However, there are several drawbacks
to these platforms. First, proteins can lose their mobility in these systems, impairing their
function. Second, there is no good way to discriminate between analytes that bind to the
same surface ligand within these platforms. Third, separation, purification, and formation of
arrays of membrane species is difficult, impeding the progress of rapid combinatorial
assaying of membrane proteins.
Results will be presented on studies conducted to understand these issues and strategies to
overcome them. By investigating the behavior of protein-protein interactions on SLBs, we
found that protein-packing influences the point at which diffusion is arrested in these systems.
To improve binding specificity, we devised a system for size-selective discrimination of
protein analytes that bind to the same ligand, by incorporating poly(ethylene glycol) (PEG)
lipopolymers into SLBs. Using our platform, we were able to achieve discrimination of
several orders of magnitude. Finally, we developed a technique to separate membrane
species within an SLB: bilayer chromatography. Results will be presented that show our
separation method is sensitive enough to differentiate isomers of dye-labeled lipids and is
currently being extended to the separation of membrane proteins.

Microbial fuel cell operation for electricity generationZhen HeDepartment of Energy, Environmental and Chemical Engineering
Washington University in St. LouisWe have developed upflow microbial fuel cells (UMFC) that simultaneously can clean wastewater and produce electricity. By sufficiently utilizing the inner volume of the anode and minimizing the space between electrodes the power output of the UMFC was improved from 3 to 25 W/m3. We are also working on harvesting electric energy from natural waters (e.g. river and ocean), with a novel design of a rotating cathode in a sediment microbial fuel cell to improve oxygen availability to the cathode. Finally, we have adopted a bacterium found in the normal human gut microbial community whose genome has been sequenced as a model anode biocatalyst to study its genomic variations using DNA chips. First year MASC students are required to attend.
