Lifetime Physical Activity
  • He came to Sonoma State in the Fall of 2020 as an Assistant Professor.
  • He was born in the State of Indiana, but moved to South Korea when he was a year old.
  • He was a Division 1 soccer player at Seoul National University (SNU), South Korea, under Korea University Football Confederation (KUFC), and then became an assistant coach for the SNU soccer team while he is working on his Master’s degree.
  • In Korea, he was a PE teacher, athletic trainer for high school student-athletes, and director of many adapted physical activity programs.
  • He came to Mississippi State University to study motor behavior and exercise science in individuals with all abilities. Currently, he is working on connecting both areas of study, motor learning and adaptive physical activity, to support the disability population and their family to be more physically active and healthier.
  • He is not currently playing soccer although he would love to; instead, he enjoys golf and tennis. He is a single golfer (handicap: 7 over par) and won a champion of the Rohnert Park Tennis Club adult doubles league (USTA 4.0) in 2021.

His Curriculum Vitae

  • Ph.D. in Exercise Science, emphasis on motor learning in intellectual disability, Department of Kinesiology, Mississippi State University, MS State, MS, 2020
  • M.S. in Adapted Physical Activity, Department of Physical Education, Seoul National University, Seoul, South Korea, 2014
  • B.S. in Physical Education, Department of Physical Education, Seoul National University, Seoul, South Korea, 2012
Academic Interests


Enhance motor skill acquisition in retention in individuals with all ability


  • Study motor control and learning theories and techniques that have been validated in typically developing people with healthy young adults
  • Find potentially applicable avenues to enhance motor skill acquisition and retention in individuals with developmental disabilities (e.g., attentional focus, implicit practice, and practice under reduced-error condition with higher expectancy)
  • Modify the instruction and apply them to exercise programs for people with disabilities and parents (i.e., Seawolf FIT program: click HERE for the program information)
