About me

Youngjin Park, Ph.D.

Assistant Director of EPIC / interim – EPIC HighBay Director / Research Associate Professor

Dr. Park’s expertise is geotechnical engineering with emphasis on laboratory and field experimentation, sensors and instrumentation for short- and long-term monitoring.  Examples of recent research topics include resilient modulus testing, erosion protection of dams through adequate filter materials, and the modification of a new resonant and torsional shear testing device.
