She received her master’s degree from the University of Delaware (Winterthur Program in Early American Culture) in 1999 and completed significant courses of study in the history of art in Rome, Italy, and throughout Great Britain.

Mrs. Kirtley joined the American Art department at the Philadelphia Museum of Art (PMA) as a curator in 2001.

Her work has included overseeing a furniture collection survey (Luce Foundation); installing a series of small, innovative exhibitions (Getty Foundation); managing furniture conservation and upholstery treatments (Americana, Luce, von Hess, and Miller-Worley Foundations and PMA Women’s Committee) and architectural preservation (Wm. B. Dietrich Foundation). She received the endowment for her curatorial position (H. F. Lenfest and R. L. McNeil, Jr.) in 2009.

In addition to smaller exhibitions, Alexandra curated the retrospective “Colonial Philadelphia Porcelain: The Art of Bonnin & Morris” in 2008 and the groundbreaking “Classical Splendor: Painted Furniture for a Grand Philadelphia House” with conservator Peggy Olley as co-curator in 2016. Also in 2016, she and her curatorial colleagues began planning in earnest for the newly located, reinstalled, and reinterpreted galleries for early American art; postponed by COVID-19, these long-awaited new American art galleries opened to much fanfare and critical acclaim in May 2021.
