Sasa Caval
Administrative Assistant, Institute for Research in the Social Sciences
Staff,BioDr Saša Čaval is an archaeologist whose research explores how landscapes, memory, and material culture shape communities across time. She leads the ERC project STONE, examining the origins and meanings of the medieval stećci tombstones of the Western Balkans. Her work integrates archaeology, geoarchaeology, and digital heritage technologies to study long-term human–environment relationships.
At Stanford, Dr Čaval is affiliated with the Stanford Archaeology Center and the Institute for Research in Social Sciences. She also works with the Mauritian Archaeology and Cultural Heritage project group, connecting archaeology with post-colonial histories and community-based conservation. She also contributes to GeoAI, Slovenia’s national research programme applying artificial intelligence to cultural-heritage risk modelling.
A Marie Skłodowska-Curie alumna (University of Reading, UK) and active member of the Marie Curie Alumni Association (Coordinator for the West Coast), she promotes inclusive, ethically grounded research that links local communities, digital innovation, and global heritage stewardship. -
Lynette Cegelski
Monroe E. Spaght Professor of Chemistry and Professor, by courtesy, of Chemical Engineering
Current Research and Scholarly InterestsResearch in the Cegelski laboratory is driven by the need to uncover and define the chemistry that underlies outstanding challenges in human health, the environment, and sustainability. Beyond discovery, we use chemistry as a tool to innovate and create solutions to these pressing problems. The laboratory is highly interdisciplinary, designing experimental approaches to understand how complex biological systems are built, organized, and controlled, and then perturb and influence assembly processes. The lab develops new methods and uniquely leverages: (1) small molecules in new biochemical assay development, chemical genetics approaches, and therapeutic discovery in infectious diseases, (2) fluorescence and electron microscopy coupled to analytical HPLC, mass spectrometry, and complementary biochemical techniques, and (3) spectroscopy, particularly solid-state NMR, to uncover new “dark matter” and define chemistry in insoluble, heterogeneous and complex assemblies relevant to human health, plants, and the ocean.
Long-standing efforts in the laboratory focus on defining mechanisms underlying bacterial biofilm formation and identifying new antibiotic and anti-virulence strategies, including advancing therapeutic candidates for the most difficult-to-treat infections. Through these efforts, we uncovered a new chemical structure in nature: phosphoethanolamine (pEtN) cellulose. Cellulose is the most abundant biopolymer on earth and this discovery provided the first experimental validation of a naturally produced chemically modified cellulose. We are developing alternatively modified celluloses and polysaccharides and advancing new solutions for ecofriendly, sustainably sourced, and recyclable materials. Collectively, our projects span disciplines from molecular structure and assembly chemistry to living microbial communities and natural marine systems, while aiming to translate fundamental discoveries into therapeutic and materials solutions.
