Angelyn, a specialist in the in situ conservation of architectural features, finishes, and wall paintings, has been lead wall paintings conservator at San Bartolo and Xultun since 2002. She is a Research Assistant Professor of Anthropology at the University of New Mexico, and principal at Conservation Associates. Angelyn’s current research interests include micromorphological analysis of earthen plasters, preservation of earthen/stone masonry architecture and earthen architectural finishes on Pueblo archaeological sites in the American Southwest including ancient Pueblo murals at Canyon de Chelly and Mesa Verde, and the conservation of Preclassic- and Classic-period Maya wall paintings on lime plasters at several sites in Guatemala.

David is an archaeologist with over ten years of experience, including the excavation of Preclassic monumental architecture at Xultun and royal residential architecture of Bejucal, Guatemala. In addition to his role on PRASBX, David works on Guatemala’s southern coast and in the highlands, and he brings this diverse regional experience to his survey and GIS work as a part of the project.

Laura is an archaeologist with previous experience at a number of Preclassic through Postclassic sites in Guatemala. While her archaeological focus has been on figurine use and household ritual, her work also reaches into public archaeology to include education and community development. Laura draws on these experiences as part of the San Bartolo-Xultun project where she is both directing archaeological investigations and coordinating outreach to nearby communities in Petén. She loves working in the ancient sites surrounded by tropical jungles!

Rob is an environmental anthropologist and remote sensing specialist, with expertise in the study of human-environment interactions across Latin America. He is currently Associate Dean of the College of Science, University of Alabama in Huntsville, and is an Associate Professor in the Department of Atmospheric and Earth Science, where he collaborates with various researchers and students on applied science issues critical to understanding the dynamics between the Earth’s surface and atmosphere. Rob participated in the original mapping of San Bartolo, returning in 2019 to work with lidar data and direct project investigations related to anthropogenic modifications of past and present ecosystems in the Maya Biosphere Reserve. Rob enjoys hiking with his wife Clare and their three children.

Kelsey is a research associate at the University of Alabama in Huntsville, where she specializes in using remote sensing to address long-term landscape change and resilience, including space archaeology. Kelsey also works as a research scientist with the NASA SERVIR program, focusing on the assessment of coastal resilience in Latin America, primarily through mapping and monitoring of mangrove ecosystems. Her previous projects include using Synthetic Aperture Radar (SAR) to detect gold mining in Peru, monitoring ephemeral water bodies in the West African Sahel, mapping ancient Chacoan archaeological features with repurposed NASA airborne data, and developing habitat suitability models to support National Forest management in Alabama. Outside of work she enjoys discovering the extraordinary biodiversity of the southeastern U.S. with her husband, kids, and dog! Prior to university, Kelsey trained to be an opera singer!

Josué is an independent scholar with over ten years of experience as an architectural draftsman and archaeological assistant for projects at Copan, Tikal, Holtun, and Tintal, as well as San Bartolo-Xultun. In addition to his expert skills as a draftsman, Josue has been learning GIS and is a key member of the ground survey team. Josué’s familiarity with Maya architecture enhances his work to identify architectural features under dense forest coverage and map these features. He also tends to have remarkable luck in finding new monuments.

Doug holds a research faculty position in the School of Engineering, University of Vermont, where he is exploring the roles of engineering in architectural conservation. He is an expert member of the ICOMOS International Scientific Committee on Earthen Architectural Heritage (ISCEAH) and the ICOMOS International Scientific Committee on the Analysis and Restoration of Architectural Heritage (ISCARSAH). Since 2011, Doug has been involved in the micromorphological characterization of ancient plasters and earthen construction materials and structural health monitoring of archaeological sites in the Southwest U.S., including Canyon de Chelly, Casa Grande, Montezuma Castle, Tonto, and Natural Bridges National Monuments.

Franco, currently Lecturer in Archaeological Materials at MIT, holds many roles across the project as an archaeologist, epigrapher, and art historian. His research explores how writing, expertise, and representations of nature were managed within Maya statecraft, and the ecological implications of these processes. A project member since 2008, much of Franco’s research focused on the Late Classic period murals discovered at Xultun Structure 10K-2 in 2010. He is currently directing the documentation of stelae and excavations associated with carved monuments at Xultun, and is leading the project’s digital humanities initiatives to disseminate the art and architecture from San Bartolo and Xultun.

David is the Schele Professor of Mesoamerican Art and Writing in the Department of Art and Art History at The University of Texas at Austin. His research focuses on the art, archaeology and epigraphy of ancient Mesoamerica, with a focus on Maya civilization. Since the late 1970s he has been at the forefront of the decipherment of Maya hieroglyphic writing and visual culture. His early work on Maya art and writing led to a MacArthur Fellowship (1984-1989), A Guggenheim Fellowship in 2007, and a UNESCO Lifetime Achievement Award in 2012. As project epigrapher, David is examining the corpus of early writing from the San Bartolo murals, as well as new texts from Xultun and Xulbe. More broadly, his research is focused on the Maya sites of San Bartolo, Copan, Palenque, and La Corona, as well as in the study of central Mexican script and image.
