Jade d’Alpoim Guedes (Director & PI)

IMG_6141Jade d’Alpoim Guedes grew up on a small organic farm in Portugal where she collected and saved hundreds of varieties of seeds with her father. Her commitment to understanding how humans have achieved sustainable agricultural systems throughout history lead her to become an environmental archaeologist who studies how humans have adapted their agricultural strategies to changing climatic conditions.

Her primary region of focus is China, where she has carried out collaborative fieldwork and participated in projects for the past 12 years. She employs a variety of different methodologies in her research including archaeobotany, human osteology, paleoclimate reconstruction and modeling. Jade earned her Ph.D from Harvard University in 2013, and carried out a postdoctoral fellowship in the department of Earth and Planetary Sciences at Harvard University. She was previously faculty in the department of Anthropology at Washington State University.

Her current research project uses these methodologies to understand how humans adapted their lifestyles to the challenging environment of the foothills of the Himalayas. This project aims to understand why a major transition in subsistence regimes took place in the Himalayas through a collaboration with dendroclimatologists, geomorphologists and agricultural modelers.

Her other archaeological research projects include studying plant remains from the Chengdu Plain,  Thailand, Nepal and from the Harappa site in Pakistan.

Jade also works closely with crop scientists at Washington State University to examine the potential of landraces of traditional crops. Current lab research involves studying the potential of various varieties of millet for modern agricultural systems as well as traditional landraces of wheat and barley.

Lab Members at UCSD:

Fabian Toro, B.S. ( Ph.D Primary Advisee)

IMG_1630As a Paleoethnobotanist I am interested in archaeological agricultural landscapes, and how understanding these informs contemporary food sovereignty struggles and international agricultural development projects. I am concerned with how the
archaeological record can speak to practices of food production in the context of migration, dynamic socio-politics and climate change.
Employing macro-botanical analysis, organic chemical residue analysis, geoarchaeological methods and interdisciplinary collaborative approach, I seek to create high-resolution archaeological narratives that are scientifically rigorous and firmly grounded in decolonial theory.
Currently, I am working on my M.A thesis which focuses on agricultural strategies, and landscape transformation in the Proto-Silk Road during a period of significant cross-cultural interaction in Northwest China.

Nathaniel James, M.A. (Ph.D Primary Advisee)

NFJ-Thai MonkeyNathaniel’s interests focus on the interactions between early states, agriculture, and inequality: particularly the ways in which agricultural labor was directed by both individual households and larger polities.
Nathaniel’s MA thesis focuses on applying crop-processing models to the Indus Civilization city of Harappa. He has field experience in Belize, Thailand and the American Southwest, and his future work will focus on the ancient agricultural strategies employed in Gansu, China.
Yaohan Wu,(Ph.D Primary Advisee)

Picture1Yaohan is a bioarchaeologist interested in employing interdisciplinary research to understand how past people from different cultures in prehistoric times utilized different foodways to adapt to the geoenvironmental stressors around them. In particular, she is interested in studying the changes in dietary intake and temporal trends in plant and animal domestications in prehistoric China. Some of Yaohan’s previous researches include reconstructing migration patterns in Bronze Age Tuckey through dental morphology and modeling stone toolmaking among fossil hominins through entheses on hands and forearms. Her currently project focuses on the link between agricultural productivity and population during the Neolithic China.

Luke Stroth, M.A. (Committee Member)

Stroth_bio_photoIn 2016, Luke Stroth left the cornfields of the Midwest to enter the UCSD graduate program in Anthropology, focusing on Anthropological Archaeology. His interests include the human-environment relationship, archaeometry, lithic technologies, craft production and economic exchange, and Mesoamerican archaeology.

His current research focuses on the human-environment relationship at the Classic (AD 150-850) Maya site of Nim li Punit, Toledo District, Belize. Working with PI and UCSD Professor Geoffrey E. Braswell and PhD candidate Mario Borrero, Luke combines macrobotanical analysis with landscape archaeology and paleoclimate data to study how subsistence practices were influenced by large-scale environmental changes and how these changes were perceived within the Classic Maya worldview. In addition to this primary dissertation research, Luke has been involved with UCSD Professor Jade d’Alpoim Guedes’s lab in the analysis of the paleobotanical collection from Khirbat al-Jariya, an Iron Age copper production site in the Wadi Faynan, Jordan.

Previous research interests include the lithic assemblage from a Postclassic Site on the north coast of Honduras, working with Braswell, PIs Markus Reindel (PhD) and Franziska Flescher (MA), and MA student Raquel Otto. Recent work in this relatively understudied region has shown how local development and identity articulate with foreign influences. Analysis of the assemblage revealed how a Mesoamerican lithic tradition is modified by local raw materials and technological choices. In addition, he has previously worked on Midwestern lithic and hot-rock technologies during the Woodland period. Luke has excavated in Iowa, Belize, Peru, South Africa, and Chiapas. He received his B.A. from the University of Iowa in 2016 and received his M.A. from UCSD in 2018.

Service work includes a position as an editorial assistant for Latin American Antiquity (2018 to present) and the chief organizer of the UCSD Archaeology Colloquium Series (2016 to present). He has received the Katzin Prize endowed fund (2016-2021) and the San Diego Fellowship (2018-present).

Molly Carney, M.A., RPA, (Primary Advisee)

Broadly, I situate myself as an environmental archaeologist. I use paleoethnobotanical and geoarchaeological tools to explore how past people interacted with and related to natural and built environments. My dissertation research looks at the relationships between people, plants, landscapes, and environments. Specifically, I am exploring how people in northwestern North America used and managed4F5B45E8-BE48-492F-B09F-EA28298D0C18 plant foods, with a particular focus on camas (Camassia quamash). I am also interested in the architectural signatures of past Columbia-Fraser Plateau places and employ feminist, Indigenous, and agency-focused lens’ to reframe past and present discussions on regional household archaeology. I am strongly committed to collaborative, inclusive, and multivocal archaeology and anthropology, and to bridging gaps between cultural resource management, academia, and the communities who have lived in the Plateau region since time immemorial.

Samantha Lee Fulgham, (M.A. Committee Member) Multnomah Falls

I am currently pursuing my Masters in Archaeology with a focus on paleobotanical and faunal analysis. My current work is situated on the Northwest Coast in the Coast Salish

region, in Penelakut Tribal territory. I am currently looking at how feasting activity manifests in the archaeological record at a site on Dionisio Point, located on Galiano Island B.C. I am also pursuing a specialization in wood charcoal analysis, which has included training in SEM microscopy to aid in species identification. My general research interests are in human and environmental interactions, and more specifically how Native Americans have managed and utilized their natural landscapes for generations.

Piyawit Moonkham, (M.A. IMG_1069Committee Member)

I am currently a PhD student in Archaeology at Washington State University working on
a project that connects myth and folklore to historical landscape change in northern Thailand and Laos. My MA thesis examined northern Thai legends and folktales of the naga (a kind of mythical serpent) as clues to the ways that people have modified their landscape and communally adapted to disasters in the region, especially in periods after historical floods and earthquakes. I am working on developing a theoretical approach that integrates archaeological and cultural theories to understand patterns of interaction and relations between human, objects, and the environment of early historic settlements in northern Thailand and Laos, in locally-structured transitions to its complexity. My research interests also include the social networks involved in collective memory, and ethnohistorical archaeology of changing landscapes relating to historical disasters and climate changes in mainland Southeast Asia

Ryan Syzmanksi (Ph.D. Committee Member)

My interest lies in the symbiotic relationships that exist between people and their environments. More specifically, my research focus is on the continuing emergence of anthropogenic landscapes, particularly relating to the intensification of food production by foraging populations. Currently, I am involved within several projects. The first of these involves using pollen, phytolith, and fungal evidence to gain insight into the emergence of grain cultivation in East Africa. Additionally, in cooperation with the USDA Western Wheat Quality Laboratory, I am attempting to characterize carbonized wheat grain morphologies across domesticated varieties in order to improve interpretive confidence in taxonomic assignments made to macrobotanical archaeological assemblages. This will hopefully prove especially useful when dealing with very fragmentary material. Lastly, I am analyzing zooarchaeological material from Iron Age agro-pastoral sites in Kenya to better understand economic diversification and lineage cooperation during this period.

Athar Ali Khan (M.A. Committee Member)

Athar has worked as a director of the Karakorum National Park in Pakistan and has worked extensively with the FAO in participatory forestry, as well as biodiversity specialist for the IUCN.  Athar is interested in applying of Traditional Ecological Knowledge (TEK) in climate change mitigation and adaptation in Himalayas. A part of his research is to find how climate change adaptation policies are viewed in the local discourse and what material consequences that has in practice.

Andrew Gillreath-Brown (M.A. Committee Member)

Andrew is a PhD student in Archaeology at Washington State University. His research 13690629_10100569871950675_8256141592687790803_ninterests include modeling, agriculture, paleoclimate, computational archaeology, environmental archaeology, and research that surrounds how humans respond to environmental change. His dissertation research focuses on experimenting with paleoecological data (e.g., pollen) to assess whether or not different approaches are feasible for paleoclimatic field reconstructions. By using tree-ring and pollen data, we can gain a better understanding of the paleoclimate and the spatial distribution of vegetation communities and how those changed over time. These data can be used to better understand changes in demography and how people responded to environmental change. He is also interested in improving relationships between empirical and model-based researchers (see “A Dialogue Between Empirical and Model-Based Agricultural Studies in Archaeology” at As part of this interest, he is currently working with Dr. d’Alpoim Guedes on collecting data on hulled barley in the Indus Valley, primarily from the Harappa site, to better understand what may have been driving changes in barley size.

A full description of Andrew’s research and publications can be found on his website.

Jessica Devio (M.A. Commitee Member)

My dissertation examines Late-to-Terminal Classic Maya household species diversity at the site of Xunantunich in Belize. I am extensively sampling households near


Xunantunich for botanical remains to understand differences in household plant diversityusing both microbotanical and macrobotanical forms of analyses. Previously, research at the site identified large-scale food preparation activities associated with a houselot near Group E. I plan to compare the plant assemblages from this household to other nearby households. I am particularly interested in understanding the importance of manioc and other tubers in Late Classic diets. Additionally, I have begun to explore household gardening activities as part of Maya subsistence strategies. My research will contribute to discussions of Maya gardening, plant diversity, seasonality, risk management, environmental impacts, and general discussions of Maya foodways.

Cedric Habiyaremye, Ph.D (M.A. and Ph.D committee Member) 20161113_072232

Cedric Habiyaremye is a Rwandan plant scientist/PhD student in Crop Science at Washington State University (WSU). Fueled by his past as a young refugee, Cedric witnessed how hunger had its impact on the full potential for his people, in their pursuit to a better life, and during those times of hardships when he was 11 years old he vowed that when he grows up, he would study agriculture and become an expert, so he can improve agricultural systems and fight against hunger in his home country of Rwanda and other countries in Africa. Today his dreams are on their way to becoming true. Cedric is currently a postdoctoral fellow in the department of Crop Science at Washington State University (WSU), his research projects focus on agronomic practices of small grains such as quinoa, millet, and food barley to enhance the nutrition and utilization of novel and sustainable food and farming systems through interdisciplinary approaches: crop diversity, food science, and social anthropology. Besides his other agronomic projects, he is also working with Dr. d’Alpoim Guedes on evaluating the agronomic potential of various millet species and varieties for modern agricultural systems. He is also collecting data using ethnographic interviews on understanding the status of millet in farming communities of Rwanda and the potential adoption of quinoa and African millet in Rwanda to gather information about the type of crop qualities attractive to Rwandan farmers and how new crops like quinoa might be successfully integrated into their diet and what successful traditional farming strategies exist within Rwandan agriculture.

During his work in community development projects and as an agriculture student, Cedric received different awards and honors. He is a 2017 World Food Prize Borlaug LEAP Delegate, U.S. Borlaug Fellow on Global Food Security, a 2017 WSU Department of Crop and Soil Sciences Mug Award Recipient 2017. He is also a Spring 2016 Fellow of the Norman E Borlaug Leadership Enhancement in Agriculture Program (Borlaug LEAP), He is Fellow of the Association for International Agriculture and Rural Development (AIARD) / Future Leaders Forum (FLF), Class of Leaders, 2015.

Mario Zimmerman, Ph.D (M.A./Ph.D  Committee Member)Mario

Having achieved B.A. and M.A. degrees at the Universidad Autonoma de Yucatan at Merida, Mexico, my research and professional experience falls within Mayan Archaeology. I’m particularly interested in human-environment interactions, the impact and strategies of tropical pre-Columbian agriculture, as well as the social aspects of food distribution. My dissertation research focuses on the identification of areas of food preparation and consumption within pre-Columbian residences by ways of chemical residue analyses and the subsequent identification and analyses of micro-botanical elements (starch grains). The goal of my project is to obtain data relating to crop variety, diet and socioeconomic differentiation within and amongst urban Maya settlements.
