Isabel Rivera-Collazo : Principal Investigator

Isabel Rivera-Collazo

Principal Investigator

Isabel Rivera-Collazo is Assistant Professor on Biological, Ecological and Human Adaptations to Climate Change at the Department of Anthropology and Scripps Institution of Oceanography, and Directs the SIO Human Ecology Laboratory. Prof. Rivera-Collazo is native to Borikén (Puerto Rico). Her work combines earth sciences, archaeology and marine ecology to understand social vulnerability to climate and environmental change, in particular through food and habitat security in coastal and marine areas. Through geoarchaeology and archaeomalacology, Prof. Rivera-Collazo works to identify lessons from the past that are relevant to communities in the present. Her research project DUNAS, combines sand dune restoration, cultural heritage and climate change to stimulate community resilience. Most recently Prof. Rivera-Collazo leads the California Heritage Climate Vulnerability Index research project together with the CA State Historic Preservation Office. This project seeks to understand the multiple definitions of site importance, and the interface between cultural significance, climate hazards threatening heritage, and prioritization of action to mitigate climate-related impacts. Rivera-Collazo works with the Borikua / Taino communities in Puerto Rico and the Tongva community of Catalina Island in California. Her work highlights the importance of building horizontal partnerships with indigenous communities through citizen science and communal archaeology. Her practice emphasizes collaboration to identify community-relevant research questions, where the recovery of past knowledge can help decolonize historical accounts and can contribute to answer questions and solve climate-related issues in the present. She is a founding member of UCSD Climate Action Lab, and has been awarded the 2020 Climate Adaptation Leader Award and the 2020 UCSD Integrity Award.

Mariela Declet-Perez : PhD Graduate Student

Mariela Declet-Perez

PhD Graduate Student

Mariela Declet-Perez is an environmental and maritime archaeologist currently pursuing her PhD at the University of California – San Diego. Her research explores human ecodynamics with an emphasis in human adaptation to catastrophic events (i.e. hurricanes, tsunamis, earthquakes). She uses techniques from paleoclimatology, geoarchaeology, zooarchaeology and integrates current local knowledge of local communities to create a reconstruction of past marine ecosystems and climate conditions. She is currently a researcher in the Scripps Center for Marine Archaeology, Geoarchaeology Lab at UCSD, and the Laboratory for Environmental Archaeology at the University of Puerto Rico. She has a BS from the University of Puerto Rico – Humacao in Marine Biology, and a MA from Centro de Estudios Avanzados de Puerto Rico y el Caribe in Caribbean Archaeology.

Margaret A. Morris : PhD Graduate Student

Margaret A. Morris

PhD Graduate Student

Margaret Morris is a geophysics PhD candidate at SIO, co-advised by Drs. Isabel Rivera-Collazo and John Hildebrand. She is interested in knowing how to locate submerged archaeological materials using marine acoustics, and so spends a great deal of time modeling and measuring the acoustic response of artifacts. At SIO, she has become a scientific diver, ROV pilot-in-training, and amateur photographer (for creating 3D photogrammetry models of artifacts). She loves being part of a research group that cares about ethical science and focuses its work and research questions around helping communities and society. Also a fan of blueberry pancakes. Margaret entered SIO's PhD program in 2017 after earning a B.S. in Physics and Mathematics from Brandeis University.

Eric A. Rodriguez : PhD Graduate Student

Eric A. Rodriguez

PhD Graduate Student

Eric is a maritime archaeologist currently pursuing his PhD at the University of California – San Diego under the supervision of Dra. Isabel Rivera-Collazo. He is currently investigating submerged cultural landscapes in the Caribbean through his knowledge and expertise in maritime archaeology, geoarchaeology, environmental remote sensing, palaeogeographic reconstruction, and geographic information systems. He obtained a B.Phil in Anthropology and History from the University of Pittsburgh in 2012 and a MA in Maritime Archaeology from the University of Southampton in 2014, where his previous master’s dissertation focused on the reconstruction of cultural wetlands in the Humber Estuary. Since then, he has worked as an archaeologist and GIS consultant in the Americas, Italy, Great Britain, Lebanon, and Japan.

Katrina Cantu : PhD Graduate Student

Katrina Cantu

PhD Graduate Student

Katrina Cantu is a Ph.D. student at UC San Diego's Scripps Institution of Oceanography. Her research focus is how coastal environments evolve over time due to changing sea levels, climate, and human activity. Most of her work involves the collection of sediment cores and sediment analysis including identification of micro and macro fossils, geochronology, geochemistry, and stratigraphy. Katrina has conducted field work in Israel and Puerto Rico where she collected sediment cores and assisted in both terrestrial and underwater excavations. She has a BS and MS in Earth Sciences, both completed at Scripps Institution of Oceanography/ UC San Diego.

Loren Clark : PhD Graduate Student

Loren Clark

PhD Graduate Student

Loren Clark is a fourth year doctoral student in anthropology at UC San Diego under the supervision of Dra. Isabel Rivera-Collazo. Her focus is submerged prehistoric landscapes in the eastern Mediterranean, and she is working through the Human Ecology Lab as well as with the Scripps Center for Marine Archaeology. After completing BA's in Classical Civilizations and Anthropology at Indiana University, Loren participated in multiple underwater and land excavations on shipwrecks in and around the Southeastern US. She then continued on to complete a Masters of Science in Maritime Archaeology from the University of Southampton where she focused on submerged prehistoric landscapes, sea-level change, and tectonics along the Albanian coastline. Prior to joining the UCSD family, Loren spent the majority of her career in cultural resource management working with a myriad of both land and maritime sites. She is particularly interested in using her experience from CRM to continue a multidisciplinary approach to maritime archaeology in the Mediterranean.

Javier Jomar García-Colón : PhD Graduate Student

Javier Jomar García-Colón

PhD Graduate Student

Javier Jomar García-Colón is a PhD student in the archeology and bio-anthropology program at UCSD anthropology department, interested in ideas and perceptions of identity and sense of belonging. To better understand these ideas, he is interested in integrating bio-anthropological and archeological methodologies in order to give light to local community activities during Precolonial Caribbean and its reflection on modern social interactions.
