Personal Touch

I spend my free time camping, hiking, and kayaking the Mid-Atlantic, while winter brings cross-country skiing in Appalachia with my family. Coming from West Virginia, I spent my childhood on the Shenandoah and Potomac Rivers and exploring the regional National Parks, National Forests, and Wildlife Refuges open for camping. As my father, a former engineer with EPA, showed us the joys of camping, fishing, and boating; I now have the opportunity to explore the same places with my child. When not in the woods, I spend as much time traveling as possible. Hiking in South America, seeing both new and old Europe, and working and living in Sub-Saharan Africa has given me a greater appreciation for the environmental and humanitarian challenges we face. My experience allowed me to staff projects in Sumatra, Indonesia, work in Ougadugo, Burkina Faso, and work on drinking water projects in Rwanda for displaced peoples. Now and then, I indulge my love of chemistry with brewing and winemaking, a family tradition with mixed results through the years.
