Jim is a Wellcome Trust Senior Research Fellow and Reader at the Structure & Motion Laboratory. Jim's research interests cover the mechanics of both terrestrial and aerial locomotion. See his website for detail on his research.
Jim's research interests cover the mechanics of both terrestrial and aerial locomotion. He is finishing a project on the mechanics of walking in birds and toddlers (BBSRC), and is currently part of the team working on cooperative aerodynamics and radio-based animal localisation 'CARDyAL' (EPSRC). His main focus is a 5-year ‘Wellcome Trust Senior Research Fellowship in Basic Biomedical Science’ to determine the fundamental strategies and constraints of powering locomotion with muscle using limbs that also provide weight support, making use of the altered effective gravity experienced by circle-flying pigeons and terrestrial animals in a centrifuge.
