Ron Eglash

Discover Ron Eglash (born December 25, 1958) — American scholar of ethnomathematics, cybernetics, and design. Learn his background, pioneering work on fractals in indigenous art, and his ideas about generative justice and culturally situated design.

Introduction

Ron Eglash is an American academic whose work sits at the intersection of mathematics, culture, technology, and social justice. He is especially known for exploring how mathematical ideas—such as fractals, recursion, and geometry—appear in indigenous and vernacular art, architecture, and craft traditions. He coined and advanced the field of ethnocomputing, which examines how computing and culture reciprocally shape each other.

Born on December 25, 1958, in Chestertown, Maryland, Eglash has held faculty appointments at institutions such as Rensselaer Polytechnic Institute and the University of Michigan. His scholarship aims to challenge the notion that mathematics is a culturally neutral domain, and instead show how mathematical thought is embedded in lived practices and cultural designs.

Early Life & Education

• Eglash was born in Chestertown, Maryland on December 25, 1958.

• He grew up in California during the 1960s, where he was influenced both by scientific experiments and social activism.

• He earned his B.S. in Cybernetics (1981) and M.S. in Systems Engineering (1983) from UCLA.

• Later, he pursued a Ph.D. in History of Consciousness at University of California, Santa Cruz, completing it in 1992.

• As a Fulbright scholar, Eglash conducted fieldwork in West and Central Africa, investigating the use of geometric and fractal forms in traditional art and built environments.

Academic Career & Affiliations

• After finishing his Ph.D., Eglash served in roles such as lecturer in humanities and anthropology (UC Santa Cruz) and postdoctoral fellow (Oregon State University) before joining academia full time.

• He was a faculty member in Science & Technology Studies at Rensselaer Polytechnic Institute for many years, where he advanced his research on ethnocomputing.

• More recently, Eglash has been a professor at the University of Michigan, with joint appointments in the School of Information and the Stamps School of Art & Design.

• His work spans disciplinary boundaries, pulling from anthropology, mathematics, design, education, and science & technology studies.

Key Research Themes & Contributions

Ethnomathematics & Ethnocomputing

One of Eglash’s signature contributions is showing how mathematical ideas are embedded in cultural artifacts and practices. Rather than seeing math as something “external” to culture, he demonstrates that cultural designs often encode recursion, symmetry, and fractals.

He coined the term ethnocomputing as a way to frame how computing (algorithms, simulation, design tools) can be culturally grounded, not just imported into different contexts.

Examples of his work include:

• Fractal patterns in African art and architecture: He documented recursive and fractal geometries in village layouts, textiles, carvings, and hairstyles.

• Culturally Situated Design Tools (CSDTs): These are simulations or learning environments that allow students to explore mathematics through forms derived from their own cultural traditions (e.g. cornrow braiding, beadwork, urban graffiti).

• “Heritage algorithms”: Eglash describes the implicit computational rules that underlie cultural practices (for example, the rules of iteration in certain designs).

Generative Justice & Social Theory

In more recent years, Eglash has developed the concept of generative justice, a framework that argues for economic, technological, and design systems that retain value within communities rather than extracting it.

He critiques both capitalism and centralized state socialism as systems of extraction and proposes that technologies (e.g. digital fabrication, AI, maker tools) can support grassroots, self-organizing economies and value circulation.

His work also addresses issues of identity in technology, such as challenging the normative whiteness of “nerd” or “geek” culture, and exploring how marginalized communities can reclaim technology as a site of agency.

Publications & Notable Works

Some of his major works:

• African Fractals: Modern Computing and Indigenous Design (1999) — perhaps his most well-known monograph, where he brings together fieldwork and computational insight.

• Appropriating Technology: Vernacular Science and Social Power (co-editor) — a collection exploring how marginalized groups engage with and transform technology.

• Numerous journal articles and book chapters on topics such as fractal geometry in traditional arts, cultural robotics, decolonizing digital fabrication, and generative justice.

• The development and dissemination of his Culturally Situated Design Tools (CSDTs) for education.

Influence, Reception & Legacy

• Eglash’s TED Talk “The fractals at the heart of African designs” has reached a wide audience, helping bring his ideas to the public and in educational contexts.

• His work is influential in STEM education, particularly in efforts to make computing and mathematics more accessible and relevant to culturally diverse students.

• In design, architecture, and art, the motifs he studied (e.g. recursive forms) have inspired contemporary reinterpretations and design projects reconnecting with indigenous geometries.

• His concept of generative justice has potential implications for how technology, community economies, and makerspaces evolve.

Selected Quotes & Reflections

While Eglash is more often quoted through paraphrase than short aphorisms, some of his statements reflect core principles:

“The simulations do not impose math externally, but rather translate the mathematical ideas already present in the cultural practices to their equivalent form in school-taught math.”

“Both the political right and political left are focused on value extraction: socialism to the state and capitalism to corporations.” — on generative justice

(From public profiles) He was encouraged by his PhD advisor Donna Haraway to “stay in touch with your inner scientist” as he explored fractal patterns in villages.

Lessons & Insights

1. Culture is computational substrate. Eglash shows that culture can encode deep computational logic—not as a secondary ornament, but as a structure.

2. Design education can be decolonizing. By rooting computational teaching in cultural forms, learning becomes more meaningful, inclusive, and empowering.

3. Value retention over extraction. His idea of generative justice urges us to think about how our technologies serve community and circulation rather than extraction and centralization.

4. Interdisciplinary bridging matters. His career blends anthropology, mathematics, design, and technology—demonstrating that innovation often lies between disciplines.

5. Technology is not neutral. Eglash’s work underscores that the tools we build and teach reflect values, power, and identity—and can be reshaped by communities.
