Taught Masters' in Human Evolution (from October 2012)
Todd Pataky obtained his Ph.D. in Kinesiology and Mechanical Engineering from Pennsylvania State University in 2004 and pursued postdoctoral research positions at Advanced Telecommunications Research (ATR) in Kyoto, Japan, and at the University of Liverpool. Since 2009 he has been an Assistant Professor in the Department of Bioengineering at Shinshu University in Nagano, Japan, where his research has focussed on developing statistical techniques for biomechanical continuum analysis. Through this work he has collaborated internationally on a variety of research topics ranging from elephant locomotor development and the evolution of primate gait to pressure sensor development and energy harvesting.
Many classes of biomechanical data are manifested as discretely-bounded smooth continua. Examples include: (1D) elbow angle trajectories during reaching, (2D) contact pressure distributions, (3D) femoral strain distributions, and (4D) heel-pad tissue stress distributions during a loading/unloading cycle. These data are most commonly analysed by extracting (discrete) scalars which are presumably representative the underlying continuum behaviour. Unfortunately this discretization can lead to a variety of non-trivial statistical biases, mainly because scalars can vastly over-simplify complex continuum processes. An alternative is to analyse the data directly in their original sampling space using (continuous) topological statistics. This talk will highlight the philosophies and relative merits of the discrete vs. continuous approaches in the context of a variety of experimental and simulated biomechanical datasets.
