Vascular Flora of Concord, Massachusetts

In my retirement I am a Harvard University Herbaria Associate continuing to pursue botanical research on New England floristics (see atlas link at left).

Also, for fun, I read about quantum gravity and cosmology and chase other butterflies, such as my lovely wife, Erika, a nature artist. We have been thriving for more than a year on the whole-food, plant-based, no-oil, no-nuts diet proven by Caldwell Esselstyn, Jr., MD to be the best for cardiovascular health with many other qualitative well-being & measurable health benefits that we have experienced first hand.

My volunteer activities also include being a regional reviewer for the Flora of North America Project.
