Alex B. Lim is an architectural conservator based in southern Arizona and serves with the National Park Service at Tumacácori National Historical Park, where he works to preserve Spanish mission remains and associated cultural landscapes. His practice focuses on the conservation of archaeological sites, historic structures, and heritage places in partnership with descendant communities, interdisciplinary teams, and public stakeholders.
Over 14 years of public service, he has worked throughout the American Southwest—including the Four Corners region. Prior to joining the Park Service, he also worked in the arid climates of Turkey, Greece, and Azerbaijan, focusing on archaeological site conservation. His experience
spans field conservation, project planning, and long-term stewardship in complex environmental and cultural contexts. He is committed to advancing conservation practice through collaboration, public engagement, and responsible preservation of shared heritage. He holds a Master of Science from the University of Pennsylvania and a Bachelor’s degree in the natural sciences from Johns Hopkins University. His path into conservation began after a
formative semester in Florence, Italy, and an internship at the National Museum of Asian Art, which led him to specialize in architectural and archaeological conservation. An active member of the AIC, he values professional service, interdisciplinary exchange, and mentorship within the field. He is committed to strengthening connections across specialties and supporting a welcoming professional
community for both emerging and established conservators. He enjoys engaging with local cultures and languages as part of his work and daily life. He
speaks intermediate Spanish and Turkish and is fluent in Korean.
