Expertise
I will answer questions relating to the identification of bacterial and fungal isolates using phenotypic (macroscopic/microscopic appearance, biochemical bench tests, fatty-acid analysis) as well as genotypic (RiboPrinting) methods. I can also answer questions relating to environmental microbiology, especially those specifically relating to the pharmaceutical industry. I am less familiar with clinical microbiology.
Experience
I have worked within the biotech industry for 9 years, most of that time spent in a Quality Control Microbiology laboratory setting.
Within the laboratory, I routinely performed bioburden testing; sterility testing; gel-clot and kinetic LAL testing; biological indicator testing; stability testing; microbial limits testing; media performance/growth promotion testing; microbial identifications testing using API, Vitek, MIDI (GC-MIS) and RiboPrinter identifications systems; total/fecal coliform testing; environmental monitoring; media preparation; stock culture maintenance; qualification of identification test kits and QuantiCult Plus organisms. I executed the QC validation of the DuPont Qualicon RiboPrinter Microbial Characterization System. I also supported sites internationally with the fungal/microbial identification process, the RiboPrinter assay, stock culture maintenance and the microbial identification process flow.
