Human motor control system is inherently noisy, subject to long time delays, redundant, and operates on elastic effectors. Consequently, there is always some variability from one repetition of a movement to another – even for the most practiced actions such as reaching for a cup of coffee. Dr. Kuznetsov is interested in understanding the functional role of this variability with the goal of developing objective assessment methods and creating novel rehabilitation techniques. Dr. Kuznetsov utilizes time series analysis methods from nonlinear dynamical systems to assess subtle patterns of motor variability. The second focus of his research is the development of virtual reality-based rehabilitation protocols focused on altering motor variability to improve optimal human performance and to assist with recovery of motor function after neurological trauma.
In addition to his Ph.D. training, he completed two postdoctoral appointments in the Action Lab at Northeastern University (2013-2015) and Virtual Environments for Rehabilitation Lab at the University of North Carolina at Greensboro (2015-2017).
