Dr Allison Schaap
Biography
Allison Schaap is a research engineer and Assocate Head of the Ocean Technology and Engineering Group at NOC. Her primary research interest is the engineering of new technology for environmental sensing, with a focus on microfluidic system design. She has contributed to the development of a number of NOC's lab-on-chip sensors and deployed them around the world in support of a range of scientific research projects.
She received her PhD from the Eindhoven University of Technology (The Netherlands) for work on integrating optics and microfluidics to automatically identify algae species. Prior to that she completed a masters in Mechanical Engineering and a bachelors in Engineering Physics at the University of British Columbia (Canada).
