computational paleontology

Since 1994 I have been involved in developing new digital techniques to reconstruct and visualize the skeletal structure of dinosaurs, and to study their body form and kinematics. Below you can find a sampler of my research, as interactives drawn from conference presentations, journal articles, museum interactives, and animations for video productions and other media.

1. kinematic reconstruction of walking gaits

A novel computational method to reconstruct walk cycles is described which is based on the simple notion that during a walk (whether performed by a robot, modern tetrapod, or dinosaur), there are periods when two or more limbs simultaneously drive the animal forward, hence their kinematic chains must cooperate, which provides important constraint on inferring the gait.

2. inferring neck posture from modern vertebrate behavior

The curvature of the neck in the osteologically undeflected state, and how it relates to characteristic behavioral poses.

3. Visualizing allometric changes in whole skeletons

Digital animation techniques can be adopted to allow the visualization of relative growth rates in whole skeletons, using various metrics as the basis for isometric growth.
