Louis Loftus is a Ph.D. candidate in Princeton's Department of Art & Archaeology, studying 18th-, 19th- and 20th-century architecture in France, Britain and the United States. His dissertation investigates the development of hybridity as a biological analogy within French architecture between the early 18th and early 19th centuries, focusing in particular on hybridity's role in shaping and articulating perceptions of the Gothic and its potential mixture with the classical. 

Loftus received his B.A., magna cum laude, in philosophy and French from New York University in 2014. In 2021, Loftus participated in the Mellon Marron Research Consortium at the Museum of Modern Art, where he presented his findings. He has also presented his work at the Barnes Foundation, Philadelphia, and at Columbia University, and has written for the Revue de l’Art. He has been quoted on architectural topics in publications including the New Yorker and Curbed.com. In 2023, Loftus was a visiting researcher in the Department of History at the École Normale supérieure (ENS-PSL) in Paris. He is the recipient of a Fulbright U.S. Student Program research grant (2024–25) sponsored by the Centre de Recherche en Design (CRD) at ENS Paris-Saclay in support of his dissertation research in France.
