About

The Lear laboratory explores the complex interactions among microbial communities and the varied environments that they inhabit. We investigate how microbial communities adapt to human influences such as pollution events and agricultural management, as well as to natural variability in environmental conditions. A key goal of our research is to use microbial responses to such events as a quantitative indicator of the impact of human activities on New Zealand’s fragile soil and freshwater environments. In our laboratory, we therefore use modern molecular tools to conduct a wide-range of research in the broad fields of microbial ecology, biotechnology and environmental science. We share a broad-range of interests in both pure and applied aspects of environmental microbiology and are always keen to help motivated individuals investigate diverse research interests.
