Karen's life was characterized by a generosity of spirit, an uncommon warmth of personality, and a light-hearted sense of humor. A woman of many passions, Karen had a great love for nature and she pursued many outdoor adventures, particularly hiking. The breadth of Karen's life experiences also cemented in her a deep commitment to service to others both in Arizona and abroad. Her spirit, passion and philanthropy truly knew no borders. In Arizona, Karen worked for 17 years at the University of Arizona's Lunar and Planetary Laboratory. She was also a highly regarded graphic artist. Karen's loss will be felt deeply not just in Arizona and her home-state Nevada, as her life transcended cultures and geographies. She spent many of her latest years traveling and living abroad, in both Canada and Peru in support of her husband's work, and her years living in Peru were marked by her work to create positive social change. In the Peruvian and Canadian communities where she worked and was well known, Karen's loss will also continue to be deeply felt. Karen, born in Las Vegas, Nevada, passed away on June 28, 2011. She is survived by her husband, Andy; her parents, multiple siblings, nieces and nephews.
