who we are

Our team of researchers conduct a unique collection of studies spanning the tropics to temperate regions and from mountains to agricultural lands.


laura K. Marsh, PHD — director and Co-Founder

Dr. Laura Marsh has worked all over the world in tropical rainforests studying everything from plants to monkeys to jaguars to people. She taught climate change education on behalf of the Department of Energy in the Arctic (North Slope of Alaska), Papua New Guinea, the Republic of Nauru, Australia, and the US. Dr. Marsh has published in professional journals on many aspects of science, conservation, and education, including two edited books called Primates in Fragments. The second volume, published in the fall of 2013, is listed as Springer's top 25% of science downloads every year since its launch. Dr. Marsh's monograph revising the taxonomy of the Pithecia genus in a special edition of Neotropical Primates is the largest revision for any Neotropical primate genus in more than half a century. She described 16 total species, 5 of them new to science. She lead the successful HOUSEBOAT AMAZON expedition in Brazil where the “missing” saki monkey, Pithecia vanzolinii was reconfirmed alive. She has a B.S. in Animal Behavior with a minor in English from U.C. Davis, an M.S. in Ecological Ethnology from San Francisco State University, an M.A. and Ph.D. in Tropical Ecology/Anthropology from Washington University, St. Louis, and was a post-doc and technical staff member at Los Alamos National Laboratory. In addition to her science work, Dr. Marsh is a screenwriter, playwright, and fiction author.

Research Interests
Primates in fragmented landscapes, including the current development of a Primates in Fragments Management and Conservation Guidelines with the IUCN. Leading expeditions to study, survey, and discover new locations in the Amazon via Houseboat Amazon’s continuing explorations. She is particularly interested in working on both a feature and documentary series of the namesake of one of the newly described species, Pithecia isabela, named for the remarkable and courageous Isabel Gramesón Godin, considered "the first woman of the Amazon," who lived in Colonial Peru (now Ecuador) in the 18th century and was the first woman to survive, at times alone, a grueling 5,000-mile expedition originating from her city in the Andes, all the way across the Amazon basin to French Guiana.

PETER BEESON, PHD — Research Associate

Dr. Beeson earned his M.S. and Ph.D. in civil engineering from Penn State University and a B.S. in geology from Bates College. For over twenty years, Dr. Beeson has worked to incorporate GIS and remote sensing into hydrologic models ranging from simulating effects of wildfires on water capacity to the effects of agricultural practices on water quality. His experience has included projects for Los Alamos National Laboratory and the US Department of Agriculture in seven different states and Mexico. He’s currently working for USDA’s Economic Research Service mapping tillage and cover crop practices across the US to study peer-effects in adoption behaviors of producers.

Research Interests
Integrated hydrologic modeling predicting water quality and quantity responses to changing environments, agro-eco-hydrology benefits to cropping systems from conservation practices, algal biofuel production, pervious pavement systems, and storm water bioremediation.



Dr. Mark Jankowski is an ecotoxicologist at the US Environmental Protection Agency with a strong focus on assessing the effects of pollutants on salmonids in the Pacific Northwest. Much of his work is regulatory in nature, however some current recent research includes the incorporation of "omics" based tools into questions of susceptibility of organisms to metals. Given his background and interest in immunology and infectious diseases in birds, his work at Michigan State University has been as a collaborator with Dr. Jen Owen on an avian influenza project. His past positions have included ecotoxicologist with the US Fish and Wildlife Service and Wildlife Disease Investigator with the US Geological Survey’s National Wildlife Health Center in Madison, WI. He earned his B.S. in Biology from the University of Wisconsin-Eau Claire, a Masters in Public Health from the University of Utah and a Ph.D. in Molecular and Environmental Toxicology from the University of Wisconsin-Madison. 



Mr. Hathcock is a wildlife biologist with 18 years experience. Currently he works as a federal action agency biologist at Los Alamos National Laboratory. He has a strong background in NEPA and ESA compliance including work analysis, impact mitigation, and section 7 consultations. He also has a diverse background in wildlife biology with special emphasis on avian studies. His research interests are in avian population demographics and how avian populations are affected by impacts such as habitat fragmentation or climate change. 



Dr. Loftin works as an Environmental Professional at Los Alamos National Lab. He specializes in botany and watersheds with particular skills in Environmental Science, Environmental Awareness, Field Work, Statistics, Science, Water Quality, Ecology, Climate Change, Environmental Policy, Research, GIS, and Environmental Compliance.
