Gait transitions in an extinct crocodile-line archosaur

How can we determine how extinct animals move? In this poster presentation for AMAM 2021, we combine predictive simulation with fossil trackway data to provide evidence of an unusal gait transition, for the first time in an extinct pseudosuchian 

Running costs revealed through reduced gravity

What can reducing gravity tell us about running in normal gravity? In this talk for the Human Performance Lab seminar series, I show how people change their gait in reduced gravity, and what that tells us about dominant locomotor costs.

Energetically Optimal Quadrupedal Locomotion

This was an invited talk at the Human Performance Lab. I reviewed much of my thesis work under Dr. John Bertram and Dr. Jessica Theodor. Presented in Calgary, AB, Canada

Thesis

Coordinating fore and hind locomotion 
when two strategies are better than one

Many quadrupeds have shorter forelimbs than hindlimbs. What does that mean for their optimal movement strategy? Presented at ISB / ASB 2019, Calgary, AB, Canada.

Abstract

Rock me Gently 

converse effect of pitch moment of inertia on energetics and stability.

Most mammals trot, but giraffe and elephants don't. Why? Here I show that it comes down to trading off energy costs of up-and-down oscillations vs pitching back and forth. Presented at Dynamic Walking 2019, Canmore, AB, Canada.
