Gonçalo Marta, Ph.D Biomechanics
Gonçalo’s true love is running. The 'biomechanical eye' he developed during his Ph.D. studies in Biomedical Engineering makes it impossible for him to watch a runner pass by without analysing their form and judging their shoe choice. His love for running shoes runs so deep that his favourite film isn’t even a film - it’s the Breaking2 documentary, an ode to the Nike Vaporfly 4% and the science that reshaped marathon history. And when he’s not dissecting midsoles, foams, and carbon plates, he’s working with an athletics club on the track, helping sprinters and middle‑distance athletes refine their biomechanics.
