Writer / Reviewer

I've published articles and poetry. My independent research is up at

I'm also a technical reviewer for publishers.

Enthusiastic Amatuer Naturalist

I'm an enthusiastic data gatherer in the citizen science community. I'm more or less interested in every living creature, but over the years, birds and moths in particular have captured my imagination.

I've recently posted my 26,000th iNaturalist observation. In Essex County, Ontario I have nearly 3X more observations than the next highest observer.


I'm an avid reader and you can find me on Goodreads. I'm also collected a number of quotes from my reading.

My "Bug Year"

In 2023, I documented 655 research-grade iNaturalist Arthropod species in Essex Coujnty, Ontario.

CBC Afternoon Drive host Allison Devereaux interviewed me about this effort. You can view the data I gathered in this inaturalist group.
