个人简介

PhD, FIChemE, FREng, C Sci I came to Sheffield from the Harwell Laboratory in1995 as part of the nineties AEA Technology diaspora. At AEA I had a number of senior management responsibilities being in charge first of the Separation Processes Service and then HTFS (subsequently absorbed by Hyprotech) and eventually being Business Development Director for AEA Technology. On arriving at Sheffield, I was the founding head of the newly formed Department of Chemical & Process Engineering. This was a period of intense growth and activity during which we spun off Chemical and Process Engineering as an independent Department, doubled our staff numbers, decided upon our major lines of research and so laid the foundations for much of the current research programme. For the first three and a half years at Sheffield I worked on a one day a week secondment to the DTI´s Innovation Unit. There I led the team that set up an infrastructure to support innovation in London.

研究领域

My personal research interests began with environmental engineering and now straddle microfluidics, green chemical processes the hydrogen economy and Carbon Dioxide Utilization (CDU). My main focus lies at the chemistry/chemical engineering interface with the aim of developing novel reactors and energy processes. This has included microfluidic devices and projects associated with lab-on-a-chip, plant-on-a-chip and high throughput screening. Nowadays, this microchemical engineering has been increasingly supplemented by work on larger scale energy producing processes, including Thermochemical Cycles and CDU, for massive scale production of hydrogen respectively to fuel the Hydrogen economy and to provide low carbon routes to transport fuels. Such work focuses on atom efficient chemical engineering processes that are often cyclic. In the case of a thermodynamically adverse reaction such as splitting water to manufacture hydrogen, only water and heat are put into the process and only hydrogen and oxygen are removed. The cycles under study include Sulphur Iodine, Copper chlorine and the Westinghouse hybrid sulphur process. We have a world leading research group in these technologies and our collaborations spread across a broad range of countries including France, Spain, Germany, the US and South Africa. More recently we have been working, under the auspices of 4CU, an EPSRC Programme Grant, on the conversion of CO2 to fuels where my particular focus has been on whole process studies and plasma reactors.
