Research Group Vacancies:

• Post-doctoral Fellow see ad: here
• Graduate Student I will probably accept one graduate student, probably at doctoral level for Sept 2021.  They will most likely work on one of:
  • * Improving SalishSeaCast in Baynes Sound including heat and ocean acidification impacts
  • * Adding a microbial loop to SalishSeaCast and investigating microplastics in the Strait of Georgia
  I have had quite a number of students write to me so I expect I will have a choice. Please note that most students in my group come from physics, mathematics, engineering including environmental engineering, atmospheric science or physical oceanography backgrounds. These positions require (in addition to meeting the requirements of graduate admission at UBC):
  • * Mathematics to PDE's
  • * Physics to rotational mechanics
  • * Course/experience in fluid dynamics or electricity and magnetism at third year of university or higher
  • * Course/experience in numerical modelling
  • * Experience or interest in biological modelling
  • * Applicants from a university where English is not the primary language of instruction require a TOEFL of 100 or an IELTS of 7.
  If you are interested in this position, please send me an email explaining how you meet all the requirements and discussion which of the potential projects you would be interested in and why.
