Joy Viola retired after 33 years at Northeastern University, Boston in a variety of administrative positions including Dean of International Affairs. Her professional travels were surpassed, however, by her natural history travels with her husband, Alfred. Together they have photographed flora and fauna on all seven continents. Their entire photographic collection has now been willed to the Center for Invasive Species and Ecosystem Health and is in the process of being transferred into the Bugwood Image Database System. Although now a septuagenarian, she continues to add to her photo collection, most recently photographing the polar bears of Hudson Bay, the birds and flowers of Costa Rica, Florida and Arizona and in 2012, the flora and fauna of Cuba. |
