Neuromechanics: Engineering the Brain with Prof. Sylvia Budday & Oscar Neumann

Apr 12, 2026

What if understanding the brain required thinking like a mechanical engineer?

In this episode of Neurocareers: Doing the Impossible, we explore an emerging field that is reshaping neuroscience—neuromechanics, where forces, stiffness, and material properties become key to understanding the brain and spinal cord.

🧭 From Engineering to Neuroscience

Professor Sylvia Budday and doctoral researcher Oscar Neumann share their unconventional journeys into neuroscience—from mechanical and civil engineering into one of the most interdisciplinary frontiers of brain research.

Oscar’s path began in civil engineering, studying structures and materials, before transitioning into modeling spinal cord tissue. Sylvia’s journey led her to apply continuum mechanics to the brain—revealing insights that traditional neuroscience alone could not explain.

Their stories highlight a powerful idea:
👉 Sometimes the biggest breakthroughs come from outside the field.

🧠 Understanding the Brain as a Mechanical System

At the core of neuromechanics is a fundamental question:
How do mechanical forces shape the nervous system?

Their work shows that the brain is not just biological—it is also:

  • Ultra-soft and highly dynamic
  • Viscoelastic (responds differently over time and conditions)
  • Sensitive to forces, pressure, and deformation

Key insights include:

  • Brain folding during development can arise from mechanical compression
  • Neural cells respond to stiffness gradients, guiding growth and regeneration
  • Gray and white matter behave differently depending on how they are tested

These discoveries challenge long-held assumptions and open new ways of understanding brain function and disease.

🧗 Challenges: Studying the Softest Tissue in the Body

Working with brain and spinal cord tissue presents unique challenges:

  • Extreme softness makes experiments difficult and highly variable
  • Results differ depending on measurement method, scale, and conditions
  • Translating findings from ex vivo to in vivo remains complex
  • Bridging language and knowledge across disciplines (engineering ↔ biology)

As Oscar describes, even measuring something as “simple” as stiffness becomes a complex scientific problem.

🔬 Bridging Scales: From Cells to Systems

One of the most exciting aspects of neuromechanics is its ability to connect multiple levels of the nervous system:

  • Cellular level: how neurons sense and respond to mechanical cues
  • Tissue level: how properties like stiffness influence structure
  • System level: how the brain deforms during surgery or injury

By combining experiments with computational models, their work aims to build digital twins of the brain—simulations that could transform research and clinical practice.

🚀 Applications & Future Directions

Neuromechanics is opening new possibilities across neuroscience and medicine:

  • Spinal cord injury & regeneration (e.g., stiffness-guided repair strategies)
  • Neurosurgery (accounting for brain deformation during procedures)
  • Brain development & disorders (e.g., epilepsy-related malformations)
  • Biomaterials design (e.g., hydrogels for tissue repair)

Looking ahead, the field is moving toward:

  • Integration of AI with physics-based models
  • Development of patient-specific brain simulations
  • Better in vivo measurement techniques

💡 Career Insights for Aspiring Neurotech Innovators

Sylvia and Oscar offer powerful advice for those entering the field:

  • Your original discipline is your strength—not a limitation
  • You don’t need to know everything about neuroscience to start
  • Learn by collaborating across fields
  • Be ready to build a “shared language” with other disciplines
  • Curiosity and persistence matter more than a perfect background

👉 Interdisciplinary science is not about switching fields—it’s about connecting them.

đŸŒ± Closing Reflection

This episode reveals a profound shift in how we think about the brain.

What once seemed unlikely—using mechanical engineering to understand neural function—is now unlocking entirely new directions in neuroscience.

As this field grows, one thing becomes clear:
The future of neuroscience belongs to those who can think across boundaries.
