Dr. Terry D. Cyr

Research Scientist

Development and application of new research methods for the analysis of vaccine proteomes and the comparison of biosimilars (subsequent entry biologics).

Current research and/or projects

Development and application of mass spectrometric methods to identify and characterize vaccines and therapeutic biologics, especially peptides and proteins in complex matrices.

Research and/or project statements

  1. Mass spectrometry (MS) of complex biologics:  Development of proteomic methodologies related to peptide analysis and the MS identification and quantification of proteins.
  2. Structural characterization of biotech products:  Characterization of the structure and determination of the purity of biotech products, biosimilars and reference standards through application of mass spectrometry.  
  3. Application of mass spectrometry to vaccine analysis and testing: Development of proteomic methodologies to identify viral vaccine strains, quantify major viral vaccine proteins and assess purity in a wide range of influenza vaccine formulations and sources. This is especially important for characterizing the reference materials that are used in vaccine manufacturing. 
  4. Mesenchymal stem cells:  Proteomic characterization of mesenchymal stem cells to develop high throughput diagnostics for the identification and quantification of therapeutic cells in stem cell-based health products.
