  • Doctoral Positions in Motor Control of Reaching: Penn State University

    Doctoral Study in Control of Complex Reaching Tasks at Penn State University:

    A PhD studentship is currently available in the Penn State University Department of Kinesiology to study mechanisms of motor adaptation. This is a collaborative project between Professors Jonathan Dingwell and Robert Sainburg in Kinesiology and Dr. Joseph Cusumano in Engineering Science & Mechanics.

    We are seeking a student interested in focusing on a project addressing motor skill learning during complex reaching tasks. This project will employ empirical experiments, as well as simulation approaches. General project goals to be pursued will be based on, but will substantially extend, ideas similar to those presented in the following papers:
    Author Summary During the repeated execution of precision movement tasks, humans face two formidable challenges from the motor system itself: dimensionality and noise. Human motor performance involves biomechanical, neuromotor, and perceptual degrees of freedom far in excess of those theoretically needed to prescribe typical goal-directed tasks. At the same time, noise is present in the human body across multiple scales of observation. This high-dimensional and stochastic character of biological movement is the fundamental source of variability ubiquitously observed during task execution. However, it is becoming clear that these two challenges are not merely impediments to be overcome, but rather hold a key to understanding how humans maintain motor performance under changing circumstances, such as those caused by fatigue, injury, or aging. In this work, by studying skilled human participants as they play a virtual shuffleboard game, we demonstrate the fundamental importance of adopting a dynamical perspective when analyzing the motor variability observed over many trials. Using this dynamical approach, we can not only study the geometry of observed inter-trial variability, but can also theoretically describe and experimentally characterize how it is temporally generated and regulated. Furthermore, our theoretical framework and model-based data analysis approach helps to unify previous variability analysis approaches based on stability, correlation, control theory, or task manifolds alone. This conceptual unification supports the idea that such seemingly disparate features of motor variability arise from a single, relatively simple underlying neurophysiological process of motor regulation.

    We expect this project to lead to empirical studies that address the functional neuroanatomy of motor adaptation through studies in neurological patients, with the long term goal of designing more effective lesion-specific rehabilitation for stroke patients.

    The Kinesiology department houses a very strong group of labs that focus on motor control and biomechanics. We have a long-standing seminar series, which attracts world renowned researchers to our campus on a regular basis, funded by the Center for Movement Science and Technology, a multidisciplinary group of scientists focused on understanding mechanisms of biological movement.

    We seek highly motivated candidates, interested in combining empirical and computational approaches to understanding human movement control. This research is at the interface between Neuroscience, Biomechanics and Bioengineering. It would be beneficial for the applicant to have a strong background in these areas, as well as computer programming skills, and relevant research experience.

    Very competitive support packages are available to highly qualified students.

    If interested please contact Professor Dingwell and/or Professor Sainburg ASAP:
