Current Research & Academic Interests

The focus of my work is on sustainability in its broadest sense, and I am particularly interested in how one can assess (measure) it. Along with several colleagues I have proposed and developed methodology that can be used for this purpose and we have applied it in a number of situations, particularly agricultural situations. Like all methods, it has limitations and there is room to do much more work to make it applicable in various different cases. Lately, we have tried to bring health issues more closely into the assessment procedures. Much of our testing has been done in low-income countries, particularly India and now Bangladesh.

    Current Environmental Studies Teachings at Queen's & Courses Taught at Queen's 

    Besides teaching many chemistry courses over a long career at Queen's, I have also taught in the School of Environmental Studies - most recently ENSC 390 (Sustainability) and (currently) ENSC 315 (Food Security) 

    Areas of Potential Thesis/Project Supervision

    General areas of sustainability – particularly related to agriculture and with a focus on holistic methods of assessment of sustainability. The focus is substantially but not exclusively on issues in low-income countries.
