Lindsey Falk, Masters of Public Health (Epidemiology) Candidate, University of Toronto


Biography:Lindsey Falk completed her undergraduate degree in biology at Queen’s University where she studied plant ecology and evolution. She is currently a second year Master of Public Health (epidemiology) student at the University of Toronto, Dalla Lana School of Public Health. Lindsey is involved with several initiatives including the Ebola Working Group, an occupational health project in Gujarat, India, and an economic evaluation of paediatric fracture pathways. At her most recent position, with the Public Health Agency of Canada, she developed a risk assessment model, predicting listeriosis risk among vulnerable Canadian subpopulations.

Lirui Feng, PhD Candidate, University of Science and Technology of China, China


Biography: Lirui Feng is currently in his final year of his combined masters/Ph.D. program at USTC, which usually lasts for 5 years. In 2014, he came to York U under the supervision of Professor Jianhong Wu via the Jointed Educational Plan and began to systematical learn about delay equations and conduct research on traveling wave of reaction-diffusion equations with non-local delay. Now, we have abstracted it to a discrete semi-system and gotten the threshold dynamics. Now, this year maybe is the last year of my PHD study, and there is a long road in my academic career in mathematics and its application. Therefore, I would like to use an ancient Chinese poem line to express my aspirations: "路漫漫其修远兮,吾将上下而求索”.

Research Interests: Dynamics of semi-flow with preserving order induced by cone of high rank, traveling waves of reaction-diffusion equations with delay, and dynamical structure of negative feedback systems with delay.
