Apart from an extensive body of work on canvas and on paper, featured in both private and public collections internationally, Van Dalen has produced multiple site-specific installations, some of them large-scale, mostly in Venezuela and the United States. In 2011, Fragmented Light was specifically designed for display at the University of Georgia’s Miller Learning Center (Athens, GA); in 2014, Natural Intersections for The Kampong Botanic Garden (Coconut Grove) and Data Hall for the Institute for Data Science and Computing at the University of Miami; and in 2022, the ephemeral installation Compass in the Sculpture Garden of The Society of The Four Arts, in Palm Beach, FL, as the 2022-2023 Beyer Artist-in-Residence.

The use of media in her body of work ranges from painting, graphics, collage, prints, drawings, and, more recently, assemblage, photography, and video, to the design of stained glass, tapestries and carpets. Her interest in the intervention of architectural spaces is similarly evident in permanent works created for private residences in Venezuela and the US, as well as public murals in Caracas, such as the urban-scale mural Jardín Lumínico, and the mural Pajaritos, both in ceramic; and in eastern Venezuela, the mosaic floor of the Jardín de Calas plaza, in Río Caribe.

She has earned various awards throughout her career, including the Second Prize at the II Biennale of Visual Arts Christian Dior, Caracas, 1991; the First Prize at the I Salón Nacional de Artes Visuales, Caracas, 1992; the 2001 competition for the commission of a large scale mural along the Prados del Este Highway, in Caracas; and the International Association of Art Critics’ 2010 Established Artist AICA Award, at the Venezuela Chapter 2011.

Van Dalen has taught at the Instituto de Diseño Foundation, the School of Architecture of the Central University of Venezuela, and the Villa Planchart Foundation, among others, in Caracas. She regularly teaches workshops at her studio in Miami, online, and in educational and cultural institutions in Miami, such as the Miami Dade College, Eduardo J. Padrón Campus and West Campus, and the Museum of Art and Design MOAD-MDC. More recently, in January 2023, she conducted five workshops on “(Re)Creating Modern Masterpieces” at The Society of The Four Arts in Palm Beach as the 2022-2023 Beyer Artist-in-Residence.

As an abstract artist, Van Dalen explores in her work the poetics of structures through the fragmentation that affects form, line, surface, space, and color.
