I have taught, researched and published in law, social work and urban and environmental planning for over 40 years. I have also been appointed to advisory commissions by 3 state governors and 3 presidents. I have published many law reviews, 2 were the first on the topic in that genre. I have published 9 volumes of encyclopedias, some with my wife Robin Morris Collin. 2 were the first in that genre - the book on the EPA was mine. The 3 volume set on sustainability was ours. My book, Battleground Environment, 2 volumes, described the 100 most controversial environmental issues from the perspective of community, government and industry. I have also been certified as an expert witness in US federal court and in state Court. I have won 2 awards teaching decided by students.

My book, The Climate Adaptation Generation: A Blueprint for the Future, was awarded the best climate change book in the US in 2025. Accepted for consideration for the 2025 Pulitzer Prize.
