Adele Ashkar, ASLA

Adele is associate professor and director of the Landscape Design Program at The George Washington University.  She has provided academic and administrative leadership, including the launch of a new master’s degree and a Graduate Certificate in Sustainable Landscapes in 2007. She guides service learning initiatives that foster outreach to the community and has initiated partnerships with area institutions, educational, municipal and non-profit. She is very active in the academic and campus initiatives towards sustainability, playing design, advisory and curricular roles on various university projects and task forces. A past president of the Potomac Chapter, American Society of Landscape Architects, Prof. Ashkar is editor of a new book, Time: Space: Landscape Architecture in the Nation’s Capital (2010). Prof. Ashkar earned a BFA in Landscape Architecture at the Rhode Island School of Design and a Master of Landscape Architecture at the Harvard Graduate School of Design. 

Hartmut Doebel, Ph.D.

Professor Doebel is the head of the beekeeping and research team.  He started this 2-year old program with a passion for honeybees and beekeeping, which he had learned as a college student in his native Germany.  By partnering with the local restaurant, Founding Farmers, he was able to dive into further research with a focus on honeybee behavior and how diseases and pesticides affect normal bee behavior.  What started as an anchor to get students excited about biology turned into a growing research program to further the knowledge about these widespread and important pollinators.

When Professor Doebel is not working on honeybees and his bee team, he focuses on his research in teaching and learning as well as how to implement active learning techniques into his courses.

Katherine Berry

Born and raised in southern California, Katherine grew up in a historical home with an avocado grove and three honeybee hives. Her interest in science is rooted in watching the bees pollinate the avocado trees. Today, she uses that same inspiration to drive her research.

Katherine plans on obtaining a Biology degree with a double minor in Health and Wellness and Fine Art at GWU. Her research focuses on palynology, more commonly known as the study of pollen. She observes pollen forager bees by tracking, marking and collecting pollen from these special worker honey bees.  With this research, we will have a better understanding of urban beekeeping, urban bee nutrition, bee foraging statistics and local flora in the DC area. Katherine is developing a map organizing the types of flowers that the bees are pollinating and their location in DC. She analyzes the pollen by looking through a light microscope and permanently mounting the grains on microscope slides using a technique she developed herself. She is also working to further look at the structure of pollen grains by using a Scanning Electron Microscope. Katherine is currently developing a methodology for building a pollen ID key. She is also on the GW Women’s Water Polo team.

Marcy Norton, Ph.D.

Marcy writes on the cultural history of sixteenth- and seventeenth-century Europe and its American colonies. Sacred Gifts, Profane Pleasures: A History of Tobacco and Chocolate in the Atlantic World sheds fresh light on the encounter between the New World and the Old World by explaining how these American Indian goods became European commodities of mass consumption. Professor Norton has held fellowships from the Kluge Center at the Library of Congress and the Davis Center of Princeton University, among others. She is currently researching cultural relativism in the seventeenth century and human-animal relationships from Columbus to Darwin.

Kim Robien, Ph.D., RD, CSO

After practicing as a clinical dietitian for more than 10 years, Kim started to find the work less fulfilling, and realized that she wanted to work in nutrition at a broader level – preventing disease rather than treating it, and helping communities rather than individuals. She decided to pursue a doctoral degree in Nutritional Sciences at the University of Washington, Seattle - a school where the nutrition program is housed in the School of Public Health. Her coursework and research projects at the university allowed her to explore the field of public health from many perspectives – nutrition, epidemiology, environmental health, and health services. Over the years in her doctoral program, and now the 10 years since completing her doctoral degree, she has become increasingly devoted to the field of public health nutrition. Her research focuses on nutrition in relation to cancer prevention and survivorship. She is also interested in environmental nutrition and sustainable food systems, and the extent to which exposure to pesticides, synthetic fertilizers and other chemicals through food and water may contribute to risk of cancer and other chronic diseases. She and her husband are dedicated “foodies” and love cooking and exploring new foods wherever they travel.
