Advising Faculty Member, GDPE
Director, Land Change Science and Remote Sensing Laboratory
My research is focused within the field of land change science. Through the use of remote sensing data (e.g., current and historical satellite imagery and aerial photographs, lidar and radar), quantitative, qualitative, and participatory fieldwork, and spatial analysis, including the use of geographical information science (GIS) and participatory GIS, I investigate the human-environment interactions that lead to land-use and land-cover changes over local and regional landscapes. Over the course of my career, I have worked on issues of land change, and the drivers of land-cover and land-use change, and livelihood systems changes in West Africa and Madagascar (during the 1980s and 1990s), and since 1997 in Southeast Asia. Since 2007 I have expanded my work to include research on climate change in Melanesia and also to the application of remote sensing and GIS to archaeology. In association with my interest in understanding the drivers of land change, I also research how human livelihoods are changing in rural, peri-urban and, in some cases, urban areas. In conjunction with this interest, I have been involved in international development projects and I investigate how development and land change interact. At Colorado State University I am the Director of the Land Change Science and Remote Sensing Laboratory, Co-Director of the Center for Archaeology and Remote Sensing, and I am on the International Development Studies Board. I am also a Returned Peace Corps Volunteer, having served in Senegal with the United States Peace Corps for three years and I am a First-Generation College Graduate.
Recent Research Projects
Land-use/cover change research
My recent projects in Southeast Asia focus on changes to the agricultural systems in the lowland and uplands in Vietnam, Laos, and Thailand. Most recently, I have expanded the focus of my research beyond general land-use/cover changes in rural areas to look at peri-urban and urban changes and linkages between these changes and rural land-use changes, and the impacts on environmental services.
My most recently completed project focused on the agrarian transition/changes in rice farming in mainland Southeast Asia. Its foci were the Red River Delta and Mekong Delta of Vietnam, Northeast and Central regions of Thailand, Savannakhet Province of Laos, and the Battambang Province of Cambodia. Fieldwork was carried out in each of the study areas and remote sensing land-cover change analysis was done for the region as a whole. More about this work can be found at https://lcluc.umd.edu/projects/agrarian-transition-mainland-southeast-asia-changes-rice-farming-1995-2018 . Fieldwork on the project was done between 2018 and 2021, papers from the project are still being developed and published.
Previous to this I led a project that focused on increased accessibility, landscape changes, rural transformations, and urbanization: Impacts of the east-west economic corridor from Da Nang, Vietnam, to Khon Kaen, Thailand. This project researched land-use/cover changes along the East-West Economic Corridor which runs 1,600-kilometer route and connects the countries of Myanmar, Thailand, Laos, and Vietnam. The project focused on the part of the corridor that connects Da Nang, Vietnam, to Khon Kaen, Thailand. Upgrades on this section of the EWEC were completed by 2007. The route passes through six urban areas, agricultural dominated coastal plains, areas of tropical montane moist forest where swidden cultivation is practiced, and across areas where permanent agriculture is practiced in a drier, savanna setting. The project investigated the impacts of the road on the urban and rural areas of these three countries with a specific focus on the telecoupled drivers of land change. More about this work can be found at https://lcluc.umd.edu/projects/increased-accessibility-landscape-changes-rural-transformations-and-urbanization-impacts-2 . Work on this project took place from 2013 – 2017, data collected during this project are still be used to develop publications, as well as for student projects.

Remote Sensing and GIS applied to Archaeological Research
The first research that I was involved with that applied remote sensing, GIS, and spatial analysis to archaeological research was in support of the work that Andrew Hardy of the École française d’Extrême-Orient (EFEO) was doing on the Long Wall of Quang Ngai in central Vietnam. I used high resolution Ikonos imagery and Corona satellite photos from 1967 to identify and map parts of the wall while a team of Vietnamese researchers walked the wall and mapped it using a GPS receiver.
At CSU the work that I have done applying remote sensing and GIS in support of archaeology is with Professor Chris Fisher. We have worked collaboratively applying remote sensing to his research sites in the Patzcuaro Basin of Mexico and research in support of identifying the city of the Jaguar in the Mosquitia of Honduras.
Information about these projects can be found at: https://archeologicalremotesensing.org/projects/
In 2020 Professor Chris Fisher and I also started the Earth Archive Initiative. The effort has the aim of digitally preserving endangered landscapes and creating an open access database of the earth’s surface.
Prospective Graduate Students
Please look my web page and see if my research is of interest to you. Within the Department of Anthropology and Geography I regularly advise graduate students who are pursuing their degree within the International Development concentration of Cultural Anthropology. I also advise students who are enrolled in the Graduate Degree Program in Ecology (GDPE), an interdisciplinary graduate degree program at CSU that offers MS and PhD degrees in Ecology. GDPE students who I advise tend to be applying remote sensing and GIS to ecological questions. Please contact me via email to explore potential options for working with me on your graduate degree. I also regularly make my Land Change Science and Remote Sensing lab available to graduate, and undergraduate, students who are using remote sensing and GIS within their research.
