Antonia Ramis Miguel was born in Spain and has been painting since childhood. Trained in Europe, she studied for seven years with Professors Edgardo and Alceu Ribeiro, themselves students of the renowned constructivist Joaquín Torres-García. Following her formal training and pursuing an interest in conservation, she spent several years studying the techniques of, among others, Rubens, Sargent, Velázquez, and Vermeer. She has also spent more than a decade painting portraits, both for exhibitions and on commission.

Miguel paints primarily in the medium of oil, on canvas and on wood; subject matter includes street scenes, still-lifes, landscapes, and figures. Recent work has included commissions for large-scale murals, as well as painted wooden sculptures. She has shown her work in individual and collective exhibitions in her native Spain, the United Kingdom, Austria, and the United States.

Miguel divides her time between Washington, DC, Palma de Mallorca (Spain), and South Wellfleet, Massachusetts. She teaches at the Truro Center for the Arts at Castle Hill, affiliated with the Art Institute of Boston, and also at the South Shore Art Center. Her work can be seen at the Julie Heller Gallery in Provincetown, MA; and the Watergate Gallery in Washington, DC.
