Alexandra Gelis is a Colombian-Venezuelan artist living and working in Toronto, Ontario. Her studio practice combines new media, installation, and photography with custom-built interactive electronics.  She uses data capture techniques, video, sound, and spatial and electronic media to create documentary based immersive installations, single-channel videos, and experimental photography.

In her work, she addresses social, political and biological concerns traced in the population and the territory by socio-bio-political interventions, through research located in specific contexts and in constant dialogue with Latin America. From this plant-based research-creation: she explores, documents and re-creates ecologies that take shape between plants and people, and between plants and their multi-species interrelationships. The idea of ​​plants as political allies is central to her concept of "Migrated Plants" as (PTTPC) Plants that have been appropriated as Technologies for Territorial and Population Control. Plants transplanted by those in a position of power to colonize (see Corridor series) but who also become allies of those in a subordinate position as a form of resistance (see plants and resistance series). This investigation takes into account the fundamental autonomous behavior of the "Migrated plants".

She has exhibited internationally in North and South America as well as Europe and Ethiopia in Africa.

In her installation work, she creates immersive sculptural spaces, using video projections and intricate sound designs. She also works as an educator/facilitator, leading video and photography workshops aimed at youth in marginalized communities in Canada, Colombia and Panama. Because she works as a workshop facilitator in several countries, in many cases, her teaching practices determine the artistic work that she creates.

Alexandra Gelis has been the recipient of numerous prizes and awards, including the Canada Council for the Arts, Ontario Arts Council, Toronto Arts Council, Colombian Minister of Culture, among others. She also won the prestigious Colciencias Doctoral Fellowship Program for her Ph.D. research: An Arts-Based Inquiry into plant/human relations in Equinoctial America: a case study of San Basilio de Palenque, Colombia.
