Research Projects

Investigation of alpha-Glucosidase I (GluI I)

Glu I is the first enzyme to act in processing oligosaccharides N-linked to proteins. While Glu I essential for normal cell biochemistry and viability in higher organisms, there is solid evidence that inhibitors of this enzyme can be effective therapeutic agents to treat disease states that manifest in abnormal glycosylation or rely on glyco-recognition.

Tyrosine/Phenylalanine Ammonia Lyase (T/PAL)

T/PALs are one of the few non-hydrolytic enzymes that have considerable industrial application. The enzyme from different sources show very different specificity for either Phe or Tyr, and this is being investigated to develop enzymes with more useful characteristics.

Tinamou Egg Proteins

Tinamous are terrestrial birds endemic to South America with commercial potential in British Columbia. There is very little information available on the protein composition of tinamou eggs. We are investigating their functional and biological properties.

Microfluidic applications in food analysis

Microfluidic systems miniaturize analyses, which allows results to be rapidly generated on-site. This makes it an ideal approach for many food analyses. We are investigating the use of molecularly imprinted polymers as a solid phase extraction medium to use in a microfluidics system.
