About Us

What we do

  • Bioactive compound isolation and characterization, Protein/glycoprotein chemistry, Purification and characterization, Glycomics, Method development, Collaboration with industrial/academic partners

Our thematic areas of research

  1. Lab-scale analytical discovery of complex glycans in foods and food streams
  2. Pilot-scale engineering to separate newly discovered glycans and produce unique food ingredients
  3. In vitro and in vivo studies to establish safety and elucidate the potential health benefits of the isolated complex glycans.


  • Our research explores how novel ‘omics combined with advances in separation science make discoveries of bioactive food components possible.
  • Using a combination of Proteomics, Glycomics, Lipidomics and Peptidomics in a cheese whey model system, our work captures previously unavailable bioactive milk components that can be rapidly adapted into novel functional foods while adding value to a waste stream.
  • With successful separation of milk components and verification of their similarity to human milk, these can serve as the basis for improved infant formulas and other therapeutic applications.
  • Based on this foundation, we recently assembled a comprehensive structural bioinformatic library for bovine milk oligosaccharides. This library includes several novel bioactive (fucosylated) oligosaccharides and will allow rapid identification of low-abundant oligosaccharides in all food streams.
  • Currently, the dairy industry must manage the cost of discarding whey permeate as a waste stream from whey protein concentrate production. Capturing the value from this waste stream as a high-value supplement and/or product for both targeted at-risk populations and for the general public could result in significant, direct economic revenue.
  • We are conducting the first human study to elucidate tolerability and effectiveness of bovine milk oligosaccharides in enriching intestinal microflora toward beneficial populations (ClinicalTrials.gov Protocol Record 264294 )
  • Our ultimate goal is to make significant contributions to the development of novel processes that reduce agricultural/industrial waste with the aim of recovering from those side-streams important bioactive components that can be used to improve health.

Our cutting edge technologies

  • Nano LC MicroChip Quadrupole ToF (Time of Flight)
  • MALDI ToF -Matrix-Assisted Laser Desorption/Ionization Time of Flight
  • HPAEC-PAD - High-Performance Anion-Exchange Chromatography with Pulsed Amperometric Detection
  • 6470A Triple Quad LC-MS - Triple Quadrupole Liquid Chromatography Mass Spectrometer
  • The combined use of these 4 analytical instruments provides a platform of technologies upon which we can investigate relatively untapped organic “waste” streams for valuable, healthful components, with concomitant mitigation of environmental pollution.
