I am the Director of the Wadsworth Center Protein Expression Core. This core performs recombinant expression and purification of proteins in E. coli, insect and mammalian expression systems. I have over 30 years of experience in the field and specialize in finding conditions for expression of soluble protein in E. coli. I have expressed and purified over 170 proteins. 

I also direct the Wadsworth Center Biochemistry Core. This core provides instrumentation for the analysis of biomolecules and complexes. Core staff help investigators design experiments, collect, analyze and interpret data.

I am the section head for Blood pH and Gases, Clinical Chemistry, Endocrinology, and Therapeutic Substance monitoring/Quantitative Toxicology for the Clinical Laboratory Evaluation Program.  I review lab developed tests, Certificate of Qualification applications, and act as a subject matter expert.
