Dr. Sarah Purdy MSc, PhD
Post Doctoral Fellow Plant SciencesSarah has a background in physics and applies her knowledge of materials, complex systems, and models to process development for lipid quality and utilization. She is an expert in spectroscopic techniques including O17-NMR, and FarIR, used to analyze plant extracts and products. She has interests in food fraud detection using spectroscopic techniques and spends extra time on science communication. She is involved with projects in the LQU group including Adding Value to Canola Seed Production, Electrostatic Conditioning of Canola Oil, Cyanogenic Glycoside Removal from Whole Flax Seeds, and Ethanol Fuel Upgrading to address the shortage of hand sanitizer in Canada during COVID-19. Dr. Purdy enjoys deciphering complex and challenging problems that don’t have a clear solution.
