Research geologist with the U.S. Geological Survey.

I have used mineralogy in my research for more than 30 years. My research has included the characterization and mineralogy of Cretaceous and Tertiary coal and coal combustion products in Alaska, northwest Colorado, western Washington, and Wyoming, mineralogy of a thick volcanic ash bed (tonstein) in northwest Colorado; mineralogy of oil ahale and saline minerals in the Eocene Green River Formation in Colorado, Utah, and Wyoming; and two new mineral papers describing kosnarite and mccrillisite.
