Dr Anthony Lewis

Associate Professor (Senior Lecturer) in Environmental Organic Chemistry

School of Geography, Earth and Environmental Sciences (Faculty of Science & Engineering)

Qualifications

I obtained my Ph.D. in organic geochemistry from the University of Bristol in 1985, having worked in the Organic Geochemistry Unit under the direction of Professor J.R. Maxwell. In January 1986, I moved to the School of Geology & Geophysics, University of Oklahoma to work with Professor R.P. Philp on the petroleum geochemistry of the Anadarko Basin. The southern hemisphere beckoned and, in April 1988, I moved on to the School of Applied Chemistry, Curtin University of Technology (formerly WAIT) in Perth, Western Australia. Whilst there, I worked with Professor R. Alexander and Professor R.I. Kagi (Centre for Petroleum and Environmental Organic Geochemistry) on the alkylbiphenyl geochemistry of the Canning Basin and the analysis of halocarbon contamination in the potable water supplies of Perth. In December 1989 I returned to the U.K. and, in February 1990, I was offered a BP EMRA by Professor S.J. Rowland in the Department of Environmental Sciences, University of Plymouth. We applied a mass balance approach to the early diagenesis of organic matter in offshore Peru sediments and observed the formation of a fraction we called "uncharacterised" on a short time-scale. After completing the EMRA, I stayed in Plymouth and accepted the post of Scientific Officer in the Petroleum & Environmental Geochemistry Group (PEGG). In the summer of 2000, I was offered and accepted a Senior Lectureship in the School of Environmental Sciences, now the School of Earth, Ocean and Environmental Sciences.

Professional membership

I am a member ot the Royal Society of Chemistry, The Geochemical Society, the British Mass Spectrometry Society and the European Association of Organic Geochemists. Between September 2001 and September 2009 I was on the board of the EAOG as the Membership and Website Officer.

Teaching interests

From January 2004 to August 2007 I was Chemistry Scheme Manager. I am currently Stage 3 Tutor and Module Leader for one module in Stage 1 of the Chemistry Scheme and also Module Leader of the Stage 3 project module of the Environmental Science Scheme. I teach a significant proportion of the organic chemistry in Stages 1 and 2 of the Chemistry Scheme, including theory and practical sessions. I continue to teach much of a Stage 1 information technology module, also for the Chemistry Scheme. This includes, amongst other topics, instruction on software packages, molecular modelling, web resources and web page construction. I am also involved in a similar module aimed at our Environmental Science students. I also have a commitment to the M.Sc in Applied Marine Sciences.

Research interests

  • Environmental organic and petroleum geochemistry.
  • Application of GC and GC-MS, in conjunction with the biological marker concept, to problem solving in a wider context.
  • Graph theoretical calculations and their application to geochemically interesting compounds.
  • Computer applications in organic geochemistry.
