Yin Fan has worked as a Water Resources Engineer for the IJC and Environment Canada for more than 6 years. She was intensely involved in the work of the Plan Formulation and Evaluation Group of recently completed IJC Study for the Lake Ontario and St. Lawrence River System (2000-2006). Dr. Fan developed and verified the computer programming of many of the components in the "Shared Vision Model" successfully used in that study. She also investigated and developed methods to simulate the flow distribution in the Lac Des Deux Montagnes-Lac St. Louis system, and also a method to estimate an ice roughness factor in the stage-discharge relationship for Lac St. Louis. Yin developed expertise in the analysis and development of lake regulation plans in the Lake Ontario and St. Lawrence River Study. She recently co-authored a conference paper titled “Hydrologic Scenarios for the Evaluation of Lake Ontario Outflow Regulation Plans”. From 1994 to 1999, she was employed by the Tecnum Group Inc. as a project manager and software developer and previously worked as a research engineer for Hydro-Quebec from 1992 to 1994.
