RAMPS: What we do

We specialize in radiation and corrosion chemistry. We investigate the chemical mechanisms of the corrosion of metals and alloys under radiation. An essential aspect of this work is modelling the concentrations and rates of production of the reactive compounds and radical species produced by radiation in various media, under a range of environmental conditions.  We are developing a more comprehensive and quantitative understanding of the influence of these "radiolysis products" on the behaviour of materials, and in particular the corrosion of metals. We also study applications of radiation chemistry in materials science (for example, nanoparticle formation). Another of our current projects involves developing methods for enecapsulating or remediating radiocontaminated materials.

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.
