My duties in the ZRU have involved printing microarrays for E. coli, Salmonella, Enterococcus, and soon for Campylobacter and helping the users detect/image them. These microarrays have been used to identify unique genes that appear in certain isolates.
 

   
  I have also helped with an Enterococcus bead array, which will be able to help identify where an isolate came from, i.e. cattle, humans, etc. While in this lab, I have also done microarray with Flavobacterium species and bead arrays with IHNV, IPNV, and VHSV.Before becoming a part of Dr. Call’s lab at Washington State University, I worked at the University of Idaho in Dr. Carolyn Bohach’s lab trying to identify E. coli O157 colonization in cattle, acid resistance of E. coli O157 in the gastrointestinal tract of cattle, and vaccine trials against the pathogen in cattle.
