Collaboration Diagrams

The following diagrams illustrate how intensely the different team members interacted, rearranging themselves into different subgroups that took on the main responsibility for individual scenes and components. Final approval for everything always came in a full-group discussion. As one of us put it, with a heartfelt sigh, “there was a lot of zooming”.

Emily Baker

Emily Baker is an architect and educator whose full-scale constructed experimentation informs her creative work and teaching. Experience on job sites in architectural practice catalyzed her search for novel structural and construction systems. Her work, employing both digital and analog design and fabrication techniques, seeks to discover new aesthetic territory embedded in the way architecture is conceived and constructed. She received a Master of Architecture from Cranbrook Academy of Art and a Bachelor of Architecture from University of Arkansas, where she is now an assistant professor at the Fay Jones School of Architecture. In 2020, she received an award from the American Institute of Steel Construction; the jury liked in particular her ongoing research on kirigami-inspired space frame construction.

Ingrid Daubechies is a mathematician, although her degree is in (theoretical) physics, and she thought she would become an engineer while growing up. Her mother was heartbroken when she opted for pure science instead, and predicted Ingrid would end up in the gutter, jobless. Fortunately, matters turned out better. Ingrid is now at Duke University. Her academic work focuses on mathematical methods for the analysis of signals, images and data, with applications in many directions. She enjoys working in collaboration with others, in her scientific work as well as otherwise; she is thrilled to be part of the Mathemalchemy team.

Dominique Ehrmann's portrait

Dominique Ehrmann

Headshot photo by Claudette Lemay

Dominique is a self-taught fiber and other media artist. Quilting is the medium she uses to tell most of her stories. She knows the rules, patterns and techniques. She uses them as a means to transport, express, touch and reinvent. First a story emerges and then it starts building up, taking shape, growing in the three dimensions. She assembles it in her head, designs it to the last detail and once ready, she turns it into a sketch. Sketches become paper models, who then become patterns, she pushes back all limits and frontiere. Her artwork plays with the wind, defies gravity, invites exploration and interaction. Her work as been seen in Museums and other exhibition halls in Canada, France and USA. She is recognised to have rocked the boat in the quilting world.

Tasha Pruitt

Tasha’s inspiration for various expressions in visual art is driven by nature, science, travel, the human experience, and the wonder of the cosmos. As most artists do, she knew from childhood that she wanted to make art. Despite not having an institutional education, she values the infinity of knowledge and is a student of life. She has worked with countless talented creators along the way. Her practice is informed by painters, musicians, sculptors, photographers, storytellers, make-up artists, scholars, fashion designers, tattoo artists, chefs… to name a few. She uses those skills with honor and relishes continuing the learning process every day while passing along the knowledge absorbed.
