Prof. Dr. John Nyakatura
John Nyakatura studied Biology and Geography at the Friedrich-Schiller-University in Jena, Germany. After completing a degree to become a secondary school teacher, he decided to persue an academic career and earned his doctoral degree in Zoology with a dissertation on the evolution and functional morphology of sloths.
As a postdoc he conducted research on the form-function-interface in the musculo-skeletal system of salamanders, lizards, birds, and primates. He routinely collaborated with paleontologists, biomechanists, roboticists, and scientific illustrators.
Since being appointed as a joint juniorprofessor at Humboldt-Universität zu Berlin in 2014, John Nyakatura leads a group concerned with the functional morphology of vertebrates and with historical and epistemic aspects of image use in his field. In 2019 he became a visiting professor at the Zürcher Hochschule der Künste.
