Ziliang "Alex" Liu is a scholar of early imperial Chinese art and architecture. His research focuses on the intersection of art and science in early China, antiquarianism in medieval China, and the reception of Han art in 20th-century East Asia. 

Liu received his Ph.D. in art history from Harvard University in 2022. His dissertation, "Art of Changes: Material Imagination in Early China, c. Third to First Century BCE," examines how understanding of materials and technologies shaped art and its perception in early imperial China, bringing together discourses in ancient Chinese metaphysics, theories of alchemy and medicine, as well as new discoveries in conservation science.
