I became Executive Director of Black Rock Solar in February 2011 after 17 years working for International Rivers, first as Campaigns Director from and then, from 2005 as ED. I wrote a book, Silenced Rivers: The Ecology and Politics of Large Dams, and numerous reports, articles, op eds, and blog posts on issues linking dams, water and energy policy, flood management, climate change, human rights and international development. Black Rock Solar installs photovoltaic power systems for tribes, non-profits in Nevada at low or no cost.
