Dr Lewis gained his BSc and PhD from the University of Wollongong and was a Senior Lecturer in Environmental/Analytical Chemistry at that University until he moved to the University of Tasmania, Launceston, in 2000. He was promoted to Senior Lecturer in 2005 and is now involved in teaching and research on both Launceston and Hobart campuses.
Research Interests
My research interests fall into two broad areas: (i) applications of conducting electroactive polymers, highly dynamic plastics that conduct electricity, and (ii) environmental chemistry. Electroactive polymers change their chemical and mechanical properties significantly and reversibly when small electric potentials are appplied to them leading to a wide range of applications, including actuators and environmental sensors (eg volatile organics and the "electronic nose"). In environmental chemistry my interests lie in water treatment, especially water recycling and reuse of industrial waters, and the analysis and fate of pollutants in environmental waters. Research projects in this area involve the removal of inorganic pollutants (eg nitrates, phosphates, metals) and organic contaminants (sludges, resins, metal / organic complexes) from industrial and agricultural effluents and industrial process waters.

Teaching
Broadly my teaching interests are analytical, physical and environmental chemistry. At first year level this covers: gases, solutions, chemical equilibria, thermodynamics, kinetics and electrochemistry. At higher levels it involves: electrochemistry (electroanalytical chemistry, solution chemistry, conducting polymers); instrumental analysis (with an emphasis on metal analysis); traditional wet chemistry techniques; water pollution and clean up and soil chemistry.
