Tatjana is a Postdoctoral Researcher in the Locomotion Research Group. Tatjana's research interest covers the mechanics of terrestrial locomotion as well as the mechanics and aerodynamics of animal flight.

Tatjana graduated in 2000 with a Diplom (MA) in Biology from the Saarland University in Germany. She completed her PhD in the aerodynamics of flapping flight at the Darmstadt University in 2006. Tatjana then became a postdoctoral associate at Brown University investigating the kinematics and aerodynamics of bats.

At the RVC Tatjana's research interests include bipedal locomotion in humans and birds and currently her research focuses on the hunting performance of cheetahs and other large African predators.

  • Dynamics and Energetics of Hunting in the Cheetah

    People: Alan Wilson, Tatjana Hubel, Kyle Roskilly

    It is well known that cheetahs are the world’s fastest sprinters, but until this study the top speed of wild cheetahs had never been measured.
    Most measurements of cheetah locomotion had been made on captive animals chasing a lure in a straight line, with few studies eliciting speeds faster than racing greyhounds.
    For wild cheetahs, estimates of speed have only ever been made from direct observation or film, in open habitat and during daylight hours. Even the highly cited 'cheetah top speed' comes from just three measured runs by one individual cheetah in 1965.
    In this study we investigate whether that single animal really did reveal the cheetah’s top speed and discover more about the cheetah's other remarkable athletic capabilities.
