Emily Baker's Portrait

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

Photo by Duke Media Services

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.

Tortoise Story

A deeper incursion in the Tortoise Story On waking up, Tess the Tortoise felt this was going to be a special day – a day to have an adventure. As always, she made a careful plan, and started her list. Breakfast first, of course – a nice leisurely breakfast; nothing good was ever accomplished onContinue reading “Tortoise Story”

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.

Currently her work focuses on the Trinidad Carnival and the craft of wire-bending embedded in this cultural design practice.


Elizabeth Paley

Elizabeth Paley spent far too much time in college, earning degrees in physics (BS, University of Illinois), astronomy (MS, University of Arizona), piano performance (BMus, Arizona), and music theory (PhD, University of Wisconsin-Madison) before throwing caution to the wind and becoming an academic expat.

She currently teaches science writing for engineers at Duke University and wheel classes for potters at Claymakers Arts Community (Durham, NC). A life-long pianist, she finds working with clay similar to practicing a musical instrument: both processes invite one to develop attention to form and detail, to balance technique with improvisation, and to discover a personal creative voice.

Path to the Garden

About a year ago, I was lucky to have attended Ingrid’s and Dominique’s presentation at the JMM where they introduced their proposal for Mathemalchemy. I immediately offered my support, but admitted that I did not feel qualified to join the group. After all, I am a mathematician, not an artist. Dominique assured me that I’dContinue reading “Path to the Garden”

Tasha Pruitt's portrait

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.

Spotlight on Stereographic Projections

Watch Henry Segerman’s video chronicle.

One of the mathematical scenes that I’ve been involved with is the lighthouse. The top of the lighthouse will have two lights – one projecting horizontally from within a stained glass dodecahedron made by Bronna Butler, and the other projecting up on the the ceiling.

This will repurpose an old project of mine illustrating something called stereographic projection. Stereographic projection is a map from the sphere to the plane. So just like the Mercator map is a way of getting the continents of the globe on a flat piece of paper, stereographic projection is another way to do that.
