Dr Nick Stevens

I am an electrochemist and computational modeller, and have been a lecturer in Corrosion and Protection in the School of Materials at Manchester since July 2003. I am part of the Materials Performance Centre , a collaboration between the School of Materials and BNFL .

I was introduced to electrochemistry as an undergraduate studying at Bath University , where I took advantage of the option to spend a year working in industry. I worked in the research division of Pilkington Technology, at Lathom in Lancashire, and was involved in a project relating to electrochromic windows.

Staying at Bath, I studied for my PhD with Dr Adrian Fisher (now at Cambridge ), performing a variety of electrochemical simulations using Finite Element methods. I developed simulations of mass transport by diffusion and convection, with coupled homogenous kinetics, in a variety of cell geometries. We also investigated the use of these simulations to design novel cell geometries.

From Bath I then travelled to Canada, where I spent a year with Professor Keith Oldham at Trent University in the town of Peterborough, Ontario, supported by an International Fellowship from the Royal Society . With Professor Oldham, I began looking at problems connected with solution resistance and simulated secondary current distributions in resistive media, and the effects of Reference electrode placement on the accuracy of voltammetric experiments.

I went to Monash University in January 2000, supported by a United Kingdom Fellowship from the Australian Research Council . My work focused on simulating the voltammetry of solutions containing low levels of Added Supporting Electrolyte, in collaboration with Professor Stephen Feldberg and Professor Alan Bond , and other group members.
