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.

My volunteer activities also include being a regional reviewer for the Flora of North America Project and serving as webmaster and creator of the neighborhood association web site, associationofgreatneck.org.
