Jim's first degree was in Applied Biology at North East London Polytechnic, specialising in plant biochemistry. This was followed by his doctoral work in the microbiology of stored topsoil on opencast mine sites.
There has been a clear emphasis on the development and application of soil microbial measurement methodology. This work has been set in a broad theme of land restoration and reclamation, and land-use monitoring in general. It has covered everything from the practicalities of providing objective ecosystem measures of the success of restoration programmes, through the interaction of governance and science, setting conceptual frameworks for restoration ecology, to educational initiatives.
Jim was appointed Chair in Environmental Technology at Cranfield in January 2002.
Professor Jim Harris' research is focused on microbial ecology and how the diversity of the microbiota and their spatio-temporal distribution affect ecosystem processes. He has applied this particularly in studying soil forming processes in disturbed landscapes and their role in organic matter dynamics; in the assessment and treatment of wastes such as landfill leachate and other wastewaters; restoration ecology and in the quantitative assessment of ecosystem goods and services.
This work has been funded by BBSRC, NERC and EPSRC, local and central government, and industry and has informed government policy, industrial practices and academic disciplines ranging from terrestrial ecology to engineered ecosystems in treatment processes.
Other research he is involved in focusses on how ecosystem principles can be used in managing modern society - from land restoration, through water treatment to the design of urban systems.
