Biography

Dr. Lemieux received her PhD in biochemistry from the University of Illinois in 1991. She has held research positions at the University of Illinois, the European Molecular Biology Laboratory, Queen's University and Neurochem (currently Bellus Health) before joining St. Lawrence College as a Professor of Biotechnology in 1998. At St. Lawrence College she collaborated on research with the company Octane.

Her previous research includes the following projects
*Identifying and studying unique enzymatic drug targets in the parasite Leishmania.
*Protein structural studies on Cytochrome o Oxidase in E. coli through DNA sequencing, site-directed mutagenesis and spectroscopic analysis of mutants.
*Development of drugs to treat various types of amyloidosis including Alzheimer’s and systemic AA-amyloidosis.
*Identification of Cord Blood Stem cell requirements for amplification in an automated tissue culture system to produce sufficient stem cells to provide immune recovery for adult patients.
