General Academic and Research Interests

David Layzell, a plant biologist, founded and was the Chief Executive Officer of the BIOCAP Canada Foundation and until July 2008 was holder of a Queen's University Research Chair in the Department of Biology. He was cross-appointed to the School of Policy Studies and held a cross-appointment in the School of Environmental Studies. He is currently taking up a new position at the University of Calgary and is an Adjunct Professor with the School of Environmental Studies, acting as co-supervisor for MES student, Kevork Hacatoglu.  In addition, David is a cofounder and part owner of a university spin-off company, Qubit Systems Inc (http://www/qubitsystems.com), that makes instruments for research and teaching in the biological and environmental sciences.
 

David's research focused in two areas. His ‘Bioeconomy Systems' research identifies the nature of the large-scale bioeconomy systems that would be needed to address climate change and energy priorities over the next 20 - 40 years, and explores the costs, benefits, opportunities and challenges associated with implementation. The research involves technology and life cycle analysis as well as proposing policy instruments and research priorities. His ‘cropping systems' research is focused on understanding how nitrogen fixing legume crops (eg. soybeans) alter the properties of soil, thereby providing a growth benefit to subsequent crops (crop rotation benefit), enhancing soil carbon pools and stimulating the production of nitrous oxide, a potent greenhouse gas.
