Ian Stavness


I am an OpenSim Fellow, one of 25 world wide experts in musculoskeletal modeling & simulation. OpenSim is a musculoskeletal simulation toolkit, developed at Stanford University, directed toward modeling whole-body biomechanics.

My group develops and evaluates new musculoskeletal simulation techniques. For example, we have developed a new general formulation for muscle-wrapping over multiple smooth surfaces that provides high performance muscle paths for simulation of musculoskeletal dynamics. My group also has a number of on-going studies applying advanced muscle models to study human balance and movement with the overarching goal of trying to reduce fall-related fractures in older adults.
