Postdoctoral Experience

Dr. Ross Carlson, Chemical and Biological Engineering July 2009 - February 2014
Montana State University

My work here is part of a broader ongoing careful study of Escherichia coli metabolism intended to improve predictive interpretation of biological networks. In this position I worked with a doctoral student providing my expertise in microbiology and proteomics. This project includes characterization of overflow metabolism, protein expression and biomass composition of cells grown in chemostats under iron, carbon and nitrogen limitation. In addition, I worked with another graduate student on efforts to improve the labs computational capability for the calculation of the elementary flux mode set for biological networks. Several papers from this work are in preparation. I also managed lab inventory by ordering supplies.

Dr. Philip Stewart, Center for Biofilm Engineering June 2007 - June 2009
Montana State University

This was two one year projects. The first examined the transcriptomic response of Pseudomonas aeruginosa biofilms exposed to antibiotics. This project included PCR, and RNA extraction. The second project screened a novel set of antimicrobials collectively known as bismuth-thiols, for the purpose of identifying those most effective against biofilms.

Dr. Joseph Frank, Department of Food Science and Technology January 2007 - May 2007
University of Georgia

This was a six month project to study survival of Escherichia coli O157:H7 on leaf lettuce under abuse and regular storage conditions similar to harvest, transport, and shelf display storage. The project considered the conditions of wilting, internalization or surface localization as factors. I was trained on the multi-photon confocal at the Center for Ultrastructural Studies at UGA during this work.
