Executive Committee

President: Lucy Johnson

Lucy Johnson is Professor Emerita of Anthropology at Vassar College.  As an Anthropologist/archaeologist, she focuses in the prehistory of the Aleutian Islands, Alaska and in prehistoric and historic sites in the mid-Hudson Valley, New York with topical interest in the prehistoric interaction of people and their environments.  Dr. Johnson is Chair of the Steering Committee, Environmental Consortium of Colleges and Universities; a member of the board of Sustainable Hudson Valley; and a member of the Hudson River Estuary Management Committee.


Vice President: Chuck Nieder

Chuck Nieder has been a biologist for NYSDEC since 1991 and has focused his career on aquatic resource assessment and protection.  He currently works in the Bureau of Habitat in Albany working to minimize the adverse impacts on aquatic resources caused by industry’s use of New York State waters for industrial cooling. Previously, Mr. Nieder held the research coordinator position at the NYSDEC Hudson River National Estuarine Research Reserve where he worked on aquatic habitat inventory, change and ecological assessment.  He developed and managed research and monitoring programs for the Reserve and managed several long-term research and monitoring programs on the Hudson River estuary. Mr. Nieder has authored and co-authored several journal papers on Hudson River estuarine ecology and holds an M.S. in Ecology from Rutgers University.


Treasurer: James Morrison

James Morrison is a vice president with HDR Engineering, Inc, an environmental science and engineering consulting company based in Pearl River, New York. Living in Marlboro, New York, James Morrison has been a resident of the Hudson Valley for over 35 years. After graduating from the State University College at Oswego with a degree in biology, Jim’s career as an environmental scientist has spanned 42 years. During those 42 years, he has been actively involved with managing environmental studies on the waterways of New York, New Jersey, and Connecticut, including studies on the Hudson River, New York/New Jersey Harbors, the East River, the Connecticut River, and Long Island Sound.


Secretary: Chris DeRoberts

Chris DeRoberts is an Environmental Coordinator for the Central Hudson Gas and Electric Corporation where he is part of a team responsible for managing environmental compliance throughout the company.  He primarily works on stream and wetland permitting for any number of transmission, distribution and substation projects (gas and electric upgrades and new

siting) as well as all environmental assessments needed in order to obtain local, state and federal approval for such projects.  He previously worked for the Putnam County Soil and Water Conservation District and the NYC Department of Environmental Protection.  Mr. DeRoberts holds a B.S in Environmental Science from SUNY Plattsburgh and an M.S in Engineering Management from Clarkson University.  Mr. DeRoberts has served on the HRES Board of Directors since September 2010.


Board Members

William Dey is vice president and senior environmental scientist with ASA Analysis & Communication, Inc., an environmental consulting company headquartered in Washingtonville, NY. Mr. Dey has more than 35 years of experience in the assessment of environmental impacts in aquatic systems, much of which was focused on the Hudson River Estuary. Over this time, he has directed or participated in many state-of-the-art aquatic monitoring and impact assessment studies throughout the United States.


Emilie Hauser has been the Coordinator of the Hudson River Estuary Training Program at the NYSDEC Hudson River National Estuarine Research Reserve since 2002. She provides science based information and trainings for local officials, resource managers, and others concerned about the Hudson Estuary. She has collaborated on several HRES events, including Rising Salt Levels in Tributaries of the Hudson Estuary in 2004 and State of the Hudson in 2009. Before that, she held several positions in recycling and household hazardous waste at the Ulster County Resource Recovery Agency. She holds a combined bachelors degree in astronomy and geology from Mount Holyoke and M.S. in earth and space sciences from Stony Brook University. She is a member and recent secretary on the Mid-Hudson Region League of Women Voters and serves on several sustainability committees in Kingston. She loves the Hudson River, including walking on it, when she uses her family’s antique (circa1869) Hudson River ice yacht, Puff.


Betty Ketcham is currently employed at the NYS Department of Transportation where she primarily works on bridge and culvert projects.  Ms. Ketcham serves on an interagency team named INTERACT which has developed statewide standards for road/stream crossings to accommodate aquatic organism passage.  A lot of work has been done in the Hudson River area to identify barriers to aquatic passage.  Ms. Ketcham is also involved with the NYSDOT Climate Change and Energy Efficiency Team which has recently identified roads, bridges and culverts that are vulnerable to climate change.  This information has been incorporated into the review process for projects.  Prior to working for the NYSDOT, Ms. Ketcham worked for the New York Natural Heritage Program which maintains the database of threatened and endangered species for New York.  She has been the volunteer treasurer of the Altamont Free Library for almost twenty years and serves on the Planning Board in the Town of Knox.


Karin Limburg

Karin Limburg, Ph.D. is a Professor in the Department of Environmental and Forest Biology at the SUNY College of Environmental Science and Forestry in Syracuse. Her doctoral thesis from Cornell University (1994) investigated the ecology of emigrating juvenile American shad in the Hudson. She was a post-doctoral fellow at the Institute of Ecosystem Studies (now Cary Institute). She has conducted research on a number of other diadromous species in the Hudson River estuary, including river herring, American eel, and striped bass and other fishes. She has also studied the process and ocnsequences of urbanization in the Hudson Valley. As a grad student, Karin was the recipient of Polgar and Hudson River Foundation fellowships; she has since sponsored seven students in the Polgar Fellowship program and one in the Hudson River National Estuarine Research Reserve Fellowship program. She has taught a field course titled "The Hudson River Watershed: Source to Sink in Eight Days," and has taught courses on watershed ecology that use the Hudson as the focus. Karin served on the HRES Board from 1994-1996 and helped to develop a conference on the history of the Hudson River estuary. Her current Hudson River research involves studies to support shad and river herring recovery.


Simon Litten, Ph.D. retired after more than 30 years at the NYS Department of Environmental Conservation as a Research Scientist.  He was primarily concerned with developing models o detect and track down toxic chemicals in water and sediments.  Dr. Litten played a role in the Hudson Estuary/New York Harbor Containment Assessment and Reduction Project (CARP).  He is also interested in sediment transport and high frequency near real-time monitoring,  He is currently researching the economic history of toxic chemicals as well as the environmental history of the Mohawk River Basin.  Dr. Litten holds a B.A. in History from the University of Oregon, an M.S. in Biostatistics from Upstate Medical Center and a Ph.D. from the Syracuse University Department of Civil engineering.  Simon has served on the HRES Board of Directors since 2009.



Emma Rosi-Marshall is an Aquatic Ecologist at the Cary Institute of Ecosystem Studies where she conducts research on factors that control and influence ecosystem function in human-dominated ecosystems. Freshwater is one of our most vital and threatened resources; understanding how human-driven global change impacts freshwater ecosystem function is essential. Dr. Rosi-Marshall's research focuses on several aspects of human modifications to freshwater ecosystems such as land use change and restoration, widespread agriculture and associated crop byproducts, urbanization and the release of novel contaminants, and hydrologic modifications associated with dams. Dr. Rosi-Marshall holds a Ph.D. from the University of Georgia.



Douglas Robinson, Ph.D. is an Assistant Professor of Biology at Mount Saint Mary College (Newburgh, NY), and teaches animal behavior and human anatomy and physiology. His interests include avian behavioral ecology, natural history, and environmental sustainability. Dr. Robinson has been studying the biology of American crows for the last 12 years and is currently investigating the prevalence of antibiotic resistant bacteria in crows in the mid-Hudson Valley. In addition to studies in North America, Dr. Robinson also leads study abroad courses to New Zealand.
