Dr. Reza Vaziri is a Professor in the Department of Civil Engineering, and served as Department Head from 2008 to 2014. He obtained his B.Sc. from the University of London, England (1982), and his M.A.Sc. and Ph.D. degrees from the University of British Columbia (1985 and 1989), specializing in mechanics of fibre reinforced composite materials. Dr. Vaziri's research is focused on the development of analytical and numerical modelling techniques to simulate the manufacturing process of composite structures as well as their fracture and damage behaviour under service loads including high intensity impact and crash loadings.

The Composites Group is actively seeking graduate students at the Ph.D. level for September 2015.
Please apply directly to email@example.com if you meet the qualifications below, citing Job Reference: DOCTORAL2015 in the subject line.
Job Description: The Composites Group is seeking to fill one or more research assistant positions (graduate student at the Ph.D. level) in the areas of numerical simulation (computational modelling) of processing and/or damage and fracture of composite materials and structures.
Qualifications: The candidate must hold a M.Sc. degree in engineering (preferably in Civil, Mechanical, Structural or Aerospace Engineering) and must have a strong background in applied mechanics and finite element modelling (computation and program development). Consideration will also be given to candidates who have a B.Sc. degree in the same areas provided that they have a proven record of relevant academic background or practical experience. The candidate must be able to work in a team since he/she will interact closely with several members of a multi-disciplinary research group. The ideal candidate would be skilled in some or all of the following areas:
- Finite element modelling or other numerical methods for solving boundary value problems in solid and fluid mechanics.
- Proficiency in a programming language (Python, C, C++, Visual Basic, Fortran) would be an asset.
- Understanding the mechanics of composite materials and the physical/chemical phenomena involved in their manufacturing.
- Knowledge in constitutive modelling of materials (viscoelasticity, plasticity, damage mechanics).
- Ability to write technical reports and to communicate effectively in professional and technical meetings.
