I post mostly on academic and political topics related to my own research on environmental change, archaeology, and human interaction with the environment. Geographically, I range across the Americas to Africa and Europe. My brother lives in Japan and so I do have some interest in Asia, although I have yet to visit.
Dr. Joseph Davidovits' experiments in ancient technology are the basis for a bold hypothesis about artificial blocks being used to build part of some pyramids in Egypt.

Geologist, archaeologist, and college science teacher. Naturally reserved in person, I more frequently let my political and scholarly opinions escape on the internet.
