Research.

Muscle

What are the mechanisms of muscle stiffness, and why are they important?

We determine how structure dictates mechanical properties.

Movement

Why do some knees carry more load than others?

We use low-cost motion analysis tools and computational models to understand human motion, joint mechanics, and muscle fatigue.

Bioinspired design

How do bighorn sheep protect their brains?

We study protective mechanisms in bighorn sheep skull and brains, with the goal of improving human safety.

Our mission

To foster individual growth through an interdisciplinary, inclusive, group-oriented culture that performs rigorous, student-led biomechanics research.

Our vision: to be the global leader in training undergraduate biomechanists.

Growth

We enable students to pursue their passions and embrace failure as part of the learning process. We believe curiosity, grit, and ownership are essential research skills, and prioritize these over technical aptitude. With individualized mentorship and strong peer support, we enable individual and scholarly growth.

Rigor

We externally disseminate biomechanics research, founded on rigorous experimental and computational methods. Successful research can take many forms; however our work is documented, ethical, repeatable, and clearly communicated to the biomechanics community.

Inclusion

We welcome students of all academic and technical ability levels. Interdisciplinarity is a core principle of our lab and a key contributor to our success, with students across colleges and departments at Bucknell. We cultivate an environment in which people with different backgrounds, identities, abilities, and perspectives can learn, contribute, and thrive.

Collaboration

We support one another through peer mentoring, open communication, constructive feedback, and shared resources. Learning about each other’s work and collaborating (internally and externally) promotes personal growth and improves the quality of our scholarship.

Muscle mechanics, modeling and undergraduate mentorship.

I founded the MMOT Lab at Bucknell in 2017. My students and I combine experiments and computational models to understand how muscles and joints carry load, and many of them go on to graduate school, medical school and engineering careers.
