Her research sits at the intersection of biology, genomics, biochemistry, and engineering—linking deeply fundamental questions about evolution and molecular biology to the possibility of next-generation materials. In this article, we explore her life, science, insights, and what her journey teaches us.

Early Life and Family

Cheryl Y. Hayashi was born in Hawaii.

She attended ** ʻIolani School** in Honolulu (Iolani High School) where she was part of the school's first co-educational class. Her formative years, surrounded by Pacific ecosystems, influenced her orientation toward the natural world and curiosity about biodiversity.

Education and Scientific Awakening

Hayashi went on to Yale University, where she earned a Bachelor of Science (B.S.) in 1988, Master of Science (M.S.) in 1990, and Master of Philosophy (M.Phil.) in 1993. Ph.D. in Biology, awarded in 1996, with a dissertation focused on the systematics of spiders using ribosomal DNA analyses.

Her path into studying spiders and silks had a pivotal turn during her undergraduate studies: she took a campus job caring for a spider colony, hand-feeding them in the lab.

Thus, what might have seemed a modest lab job became the kernel of a career exploring one of nature’s most remarkable materials.

Career and Scientific Contributions

Postdoctoral Work & Early Academic Posts

After earning her Ph.D., Hayashi served as a postdoctoral researcher at the University of Wyoming from 1996 to 2001.

In 2001, she joined the faculty of University of California, Riverside (UCR).

At UCR, she established and led a lab that combined molecular genetics, biomechanics, evolutionary biology, and materials science to study spider silk and its variation across species and function.

Research Focus: Spider Silk & Biomaterials

The core of Hayashi’s research is to understand how spider silk—one of nature’s most remarkable biomaterials—is encoded, evolved, and diversified, and to translate those insights into potential technological applications.

Her lab has characterized members of the spidroin gene family (the gene family coding for silk proteins) across many spider species, studying how different gene variants lead to differing mechanical properties in silks used for prey capture, web structure, egg case protection, defense, and more.

She uses an integrative approach: cloning full genes, transcriptomics/genomics, biochemistry, biomechanics, and comparative phylogenetics.

Beyond spiders, she has also expanded investigations to silk and glue proteins in other arthropods, comparative molecular evolution, and more broadly the role of “adaptive molecules”—how selection shapes proteins with extreme functional demands.

One striking outcome of her research is demonstrating that some spider silks exceed, in certain metrics, the toughness or performance of a range of synthetic fibers, especially considering weight and flexibility.

She collaborates widely with engineers and materials scientists to explore biomimetic applications—for instance, designing new materials inspired by spider silk for sutures, fabrics, protective gear, or sustainable fibers.

Leadership at the American Museum of Natural History

In January 2017, Hayashi moved to the American Museum of Natural History (AMNH) in New York. Leon Hess Director of Comparative Biology Research.

In 2021, she took on the role Provost and Senior Vice President for Science at the museum, overseeing scientific strategy and research across the institution.

Her staff profile states that she works at AMNH as a curator, professor, and director of comparative biology research.

She also serves on the faculty of the Richard Gilder Graduate School.

Honors & Recognition

  • In 2007, she was awarded a MacArthur Fellowship (the “Genius Grant”) in recognition of her creative, interdisciplinary research on spider silk.

  • Her body of work has been published in top-tier journals, contributing to both evolutionary biology and biomaterials science.

  • She delivered a talk at TED 2010, entitled The magnificence of spider silk.

  • Within UCR, she held Chancellor’s Chair and University Scholar awards recognizing merit and visibility in research.

Historical & Scientific Context

Hayashi’s career unfolds at a time when biomimicry, synthetic biology, and materials science are increasingly converging. The notion that insights from evolution could drive new classes of materials is a paradigm shift, moving beyond “nature as inspiration” to nature as molecular engineer.

Spider silk is a compelling model system: it combines light weight, strength, extensibility, and toughness—all generated at ambient temperature using proteins. Her work helps decode how evolutionary pressures led to multiple silk types in spiders, and how modular gene evolution and protein design principles might be generalized for engineering.

In the broader arc of 21st-century science, her bridging of genomics, biomechanics, and materials science places her among scientists who dissolve disciplinary boundaries—essential in addressing complex, multiscale systems.

Legacy and Influence

Though still active, Cheryl Hayashi’s impact is already profound:

  • She has significantly advanced our biological understanding of spider silk across species, connecting gene sequences to material properties.

  • Her work provides a blueprint for biomimetic translation—showing how deep evolutionary knowledge can guide design of sustainable, high-performance materials.

  • She serves as a role model for interdisciplinary science, particularly for young researchers drawn to combining life sciences, engineering, and design.

  • As a leader at AMNH, she shapes scientific vision, institutional priorities, and support of future generations of researchers.

Her legacy is not only scientific knowledge, but also the direction she helps give to how biology and material science cross-pollinate.

Personality, Philosophy, and Approach

From accounts and interviews, Cheryl Hayashi comes across as curious, humble, persistent, and passionate about fundamental questions. She often emphasizes that discoveries often open more questions than they answer—a recognition of science as a journey.

She fosters a lab culture that values diversity of species, methods, and perspectives, reflecting her deep belief in the richness of biological variation.

In speaking about spiders, she has noted that she was never an “insect collector” child—she began without deep affinity for them—but that being near spiders changed that perspective.

Her approach is integrative rather than narrowly specialized: she moves across genetics, biomechanics, materials science, and evolution in order to understand how molecular structure gives rise to extraordinary function.

Selected Quotes & Insights

While she is primarily known for her scientific output rather than pithy aphorisms, some of Cheryl Hayashi’s remarks capture her outlook on science and life. Below are paraphrases and quotes drawn from interviews and talks:

“Spider silks are molecules of critical adaptive significance—threads shaped by millions of years of selection.”

“It’s not just about one silk—but the diversity of silks a spider produces, each tailored for structure, capture, defense, or reproduction.”

“These [biological materials] are made at ambient temperatures and are biodegradable—properties that many synthetic materials cannot match.”

“Every time I look at a new silk gene sequence, I feel like I’m seeing something no human has ever seen before—it’s a secret between me and that spider.” (paraphrase of her sentiment)
