RAMPS: What we do

We investigate the chemical mechanisms of the degradation of materials under radiation. We are experts in radiation and corrosion chemistry. Our main objectives are to determine the distributions of radiolysis products in various media under a range of environmental conditions, to understand the influence of radiolysis products on the behaviour of materials (in particular the corrosion of metals), and to investigate applications of radiation chemistry in materials science (for example, nanoparticle formation).

We are currently looking for graduate students and postdoctoral fellows with strong chemistry backgrounds to join our group. If you are interested, fill in the contact form.

rECENT HIGHLIGHTs

  • In November, Dr. Wren attended the Corrosion Prediction and Mitigation for Key Components of Fukushima Daiichi NPS conference in Japan as an invited keynote speaker. Her lecture was entitled "Effects of Chemical and Physical Properties of Solution on Radiolysis Induced Corrosion of Carbon Steel".
  • Two of our PhD candidates, Dan Guo and Joseph Turnbull, have been awarded 2018 Roy G. Post scholarships. This scholarship was established to help students develop careers in the safe management of nuclear materials. For more information on their projects, see News.
  • Mojtaba Momeni has successfully defended his PhD thesis. Congratulations, Moji!
  • We have just finished making a new video about our research. This video shows you a few visual highlights of our work and tries to convey the excitement we feel about our research. You can watch it here: Wren Laboratory Research.
  • Wren Lab PhD candidate Mi Li won the prize for the best oral presentation in the NACE southern Ontario Student section.
  • Wren Lab PhD candidate Mojtaba Momeni won the 2017 Canadian Nuclear Society R. E. Jervis Award. This award is given to graduate students for their research accomplishments in Nuclear Engineering or related fields such as radiation chemistry, chemistry in Nuclear systems.
