### Members

**Cedric Chauve**

Department of Mathematics

Dr. Chauve's research focuses on the design of mathematical models and efficient algorithms for computational biology.

**Caroline Colijn**

Department of Mathematics

Caroline Colijn works at the interface of mathematics, evolution, infection and public health. She joined SFU's Mathematics Department in 2018 as a Canada 150 Research Chair in Mathematics for Infection, Evolution and Public Health. She has broad interests in applications of mathematics to questions in evolution and public health, and was a founding member of Imperial's Centre for the Mathematics of Precision Healthcare.

**Thomas Loughin**

Department of Statistics

Dr. Loughin is a professional Statistician and researcher with extensive experience in both statistical applications and methodological development. He has worked with researchers in a wide array of disciplines, including agricultural, engineering, medical, education, and other areas. He runs the SFU-Surrey Statistical Consulting Centre, where he focuses on communication with subject-matter experts, re-expressing complex statistical concepts into language that is easy to understand.

**Snezana Mitrovic Minic**

Department of Mathematics

Dr. Minic's research includes application of combinatorial optimization, integer programming, and graph theory to solving problems in vehicle routing, logistics, transportation, satellite mission planning, healthcare operations, and natural resource management. Snezana is especially interested in large-scale discrete optimization problems and dynamic time-constrained problems.

**Bojan Mohar**

Department of Mathematics

Dr. Mohar is a Canada Research Chair in Graph Theory, where he is developing algorithmic and computational tools.

**Abraham Punnen**

Department of Mathematics

Dr. Punnen's applied research and consulting activities include applications of optimization in industry and government. In particular he is interested in transportation and logistics, network design, routing and scheduling, timetabling, optimization applications in medicine including radiation therapy treatment planning and management of organ transplant, healthcare management, and optimization applications in forestry.

**Randall Pyke**

Department of Mathematics

Dr. Pyke earned his PhD from the University of Toronto studying nonlinear wave equations that arise in applications such as optics. His research interests also include fractals, dynamics, and simulating stochastic systems. Randall has been working to promote operations research in the math curriculum since its inception and has worked on consulting projects.

**Alexander (Sandy) Rutherford**

Complex Systems Modelling Group

Dr. Rutherford is the Scientific Director for the Complex Systems Modelling Group (CSMG). Among his research areas is health care, where he has worked on the design and evaluation of protocols for electronic health records and applications of queuing theory to surgical waitlists and the acute care system. He has also worked on application of dynamical systems methods to health care modelling, criminal justice system modelling, and epidemiology.

**Tamon Stephen**

Department of Mathematics

Dr. Stephen's research interests include optimization, algorithms and discrete mathematics. Externally he has worked with local clients in manufacturing, health care and municipal services.

**Zhe George Zhang**

Beedie School of Business

Dr. Zhang's research interests include the quantitative and economic analysis of the congestion problems in urban/mass transportation networks, health/medical care systems, and public service systems with both customer service quality and security concerns.
