I run DATA to Insight, a data visualization consulting and training enterprise. In 2010 I retired after 21 years as a research scientist at the U.S. Geological Survey in Reston Virginia, where I used GIS and applied statistics to understand landscape dynamics and the health of regions and their inhabitants. I have published on such topics as land cover and urban systems complexity, spatial forecasting for public health, fractals in geography, and urbanization in Africa. I currently teach at Northern Virginia Community College and have taught at various universities in the national capital region as well as Nigeria, Vermont, West Virginia, and southern California. I also volunteer teaching data visualization at local public schools, and my favorite activities are playing the clarinet and kayaking, and sailing.
