Biographical Sketches

        Dr. Robert Bindschadler is Chief Scientist of NASA’s Hydrospheric and Biospheric Sciences Laboratory, a Senior Fellow of the Goddard Space Flight Center, a Fellow of the American Geophysical Union and a past President of the International Glaciological Society.  He maintains an active interest in the dynamics of glaciers and ice sheets, primarily on Earth, investigating how remote sensing can be used to improve our understanding of the role of ice in the Earth's climate.  As the leader of 15 Antarctic field expeditions he has extensive first-hand knowledge of the hazards and challenges of working in the Antarctic environment.  Other research has taken him to Greenland and various glaciers throughout the world.  During his 29 years at Goddard, he has developed numerous unique applications of remote sensing data for glaciological research including measuring ice velocity and elevation using both visible and radar imagery, monitoring melt of the ice sheet by microwave emissions, and detecting changes in ice-sheet volume by repeat space-borne radar altimetry.  He has testified before Congress and briefed the U.S. Vice President on the issue of ice-sheet stability and served on many scientific commissions and study groups as an expert in glaciology and remote sensing of ice.  He has published over 130 scientific papers, numerous review articles and has appeared on television, radio and is often quoted in print media commenting on glaciological impacts of the climate on the world's ice sheets and glaciers.

Gene Carl Feldman is an Oceanographer at NASA/Goddard Space Flight Center Gene has been an oceanographer at NASA / Goddard Space Flight Center since 1985. He has been involved with the production, archival and distribution of the satellite-derived ocean color data sets, first as observed by the Nimbus-7 Coastal Zone Color Scanner and now, for the ocean color mission called SeaWiFS which was successfully launched on August 1, 1997, for which he is currently the project manager.


The applications of satellite-derived ocean color data range from providing the information needed for a more accurate assessment of the role of the ocean in global change, for providing a key parameter in a number of ecological and environmental studies, and the color images of the Earth's changing land and ocean features will be of significant use in fisheries management, agriculture assessment and coastal zone monitoring. There is no question that the Earth is changing. SeaWiFS enables us for the first time to monitor the biological consequences of that change - to see how the things we do, and how natural variability, affect the Earth's ability to support life.


Prior to 1985, Gene's experience included extended service (3 1/2 years) as a Peace Corps Volunteer in Western Samoa, where among other things he was involved in fish farming, sea turtle conservation, boat building and village fisheries development.


The author and co-author of numerous publications, Gene has also contributed to The Jason Project, Public Broadcasting, the BBC, the Discovery Channel, the National Geographic Society, the Cousteau Society, the Smithsonian Institution, and U.S. Congress Office of Technology Assessment. In addition, he has been a member of the U.S. Scientific Steering Committee for the National Science Foundation's Joint Global Ocean Flux Study, a program to study the ocean's role in the global carbon cycle. He was on the International Science Advisory Council for the Coastal Rhythms Exhibition at the New England Aquarium, and was involved with the joint NOAA/NASA project studying the Health, Ecological, and Econonic Dimensions of Global Change.

He spends as much time as possible sailing or paddling around on the Chesapeake Bay, exploring some of the many natural, and oftentimes, unnatural wonders that this area has to offer, and often refers to himself as an urban kayaker because of the more unusual places he prefers to paddle, generally with his camera by his side.

Gene earned his Ph.D. in Coastal Oceanography from the State University of New York at Stony Brook and lives in a 120 year old farmhouse along with his dog, Max,which gives him the opportunity to ride around on a little tractor, to dig in the dirt, and do death-defying feats with sharp tools.


Josh Feldmark, a lifelong Howard County resident, is the founding Director of Maryland’s oldest Office of Environmental Sustainability, having served in that role for its seven month existence.  He previously worked at the Maryland Department of Natural Resources in the Tributary Strategies program working to reduce nutrient pollution in the rivers and streams that feed into the Chesapeake Bay.

He has also consulted for Dismantling Racism Works and trained or guest lectured at over 35 colleges and universities with topics ranging from “Clean Energy on Campus” to “Anti-Racist Environmentalism.”


In addition, Feldmark served five years on the Columbia Association Board of Directors (2 as Chair), where he promoted such environmental initiatives as transitioning to chemical free pools and environmental certification of their golf courses. He has served on the Wilde Lake Village Board, the Board of Vision Howard County, and currently serves on the Board of the Baltimore Area Green Building Council, the Governor’s Commission on Environmental Justice and Sustainable Communities, and the Baltimore Metropolitan Council Sustainability Committee. He graduated magna cum laude with a Bachelor’s degree in Ecology from Rutgers University.

Cathy Hudson   I spent hours of my childhood romping in fields, swimming in creeks and ponds, exploring the woods and swinging from wild grape vines.  I haven’t stopped.  Along the way I earned a degree in Biology, took a layperson’s version of a seminary education (EFM), and later was trained in doing taxes.  Opportunities to teach in non-traditional ways kept popping up-I taught workers how to test peoples’ lung function in hospitals, I mentored groups in the four-year EFM program, I homeschooled my sons until high school, and I taught creative math to middle schoolers in a one room school house. 


Currently I am on the boards of the League of Women Voters, Howard County Citizen’s Association, Friends of the Patapsco Valley and Heritage Greenway, and the Rockburn Land Trust.  I was appointed to Howard County’s Environmental Sustainability Board as a citizen representative.  My goal is to help the environmental community in Howard County work better together on common issues.  To assist communications among the groups, I began an environmental list serve (


All in all, I enjoy building bridges between people (and groups), matching people’s passion with things that need to be done, building community, finding better ways to do things, learning new things, and advocating for the community and the environment.  To help balance my life, I enjoy gardening, raising chickens, and observing amphibians.

          Denise Sharp and her husband, Chuck have managed Sharp's Farm since 1980 when they purchased the farm from Chuck's family.  The farm is a multi generation farm with county roots centuries old.  They have focused on agricultural and environmental educational programs and production of vegetable and greenhouse crops.  For nearly 30 years, environment and sustainability has been woven into their life and farm plans.
Denise grew up with a love of gardening and nature and honed those skills with a Biology undergrad at St. Mary's College, water sampling on the Bay and playing on the Bay. After graduation, she moved to work and study at University of Rhode Island Graduate School in Oceanography, followed by further graduate study and work at Virginia Tech in Horticulture.  Graduate degrees behind her, she married a local farmer.  She returned to the farm to find that she knew very little on the practical side of things.  So she honed her practical skills by adding tech classes to her background to be able to actually do something on the farm.   Over the next several years, under the tutors of her husband, weather, economics and passion, she learned how to meld desires with pragmatic farm concerns. 
Denise says: “We reshaped the farm to meet our needs and passions and started growing vegetable to satisfy my horticulture love.  We added a greenhouse to grow a wide selection of herb and heritage vegetables and added environmental/agricultural tours.  I did indulge my passion for education and horticulture by working for the Cooperative Extension Service as a Regional fruits and vegetable specialist and State Master Gardener Coordinator for several years.  For 20 years, I wrote gardening articles.  I see sustainability, environment, footprint issues and community and family health as interconnected, a dynamic system to a healthy community.”
Sharp's at Waterford Farm is at 4003 Jennings Chapel Rd. Brookeville, MD 20833
