Faculty Faction: Jai Jung

20150921_103237_This semester YSU STEM welcomed Dr. Jai Jung as an assistant professor in the Civil and Environmental Engineering Department.

Dr. Jung joins our STEM faculty after finishing his time at Virginia Tech and the University of Waterloo, Canada, as a post-doctoral research fellow and associate where he researched trenchless technology and sustainable infrastructure management.

“Because of our existing underground infrastructure, underground utility infrastructures, including drinking water, wastewater, oil and gas lines in the United States, are deteriorating very fast and became a major problem for the governments,” Dr. Jung said. “I would like to improve and renovate our underground infrastructure, and I see a lot of opportunities in this area. That’s why I’m in a Geotechnical Engineering field.”

Dr. Jung said that eventually he would be like to be known as one of the best underground infrastructurer researchers, and he is doing some impressive research projects even though he just began his time at YSU.

“I am working on the watertight non-metal manhole system, which is designed to eliminate unwanted flows at the manhole cover and chimney area to minimize pavement degradation and sinkage around the manhole,” Dr. Jung said. “The results of this study will be used to develop further understanding of pavement degradation due to cyclic loads around manholes, investigate the effect of soil in sanitary sewer systems, and carry out life-cycle cost analysis for manhole cover system and pavement.”

The second project he’s working on is nondestructive testing for structure.

“The main objective of this project is to improve the interpretation of nondestructive condition assessment techniques for pipelines using acoustic signal processing technology,” Dr. Jung said. “Current acoustic fiber optic (AFO) monitoring can supply a pipe owner with sufficient warning to avoid a pipeline failure only when the information supplied by AFO is used to initiate an emergency pipeline shutdown fairly quickly.”

Dr. Jung said that the purpose of this research is to further research acoustic signal processing to advance the practical use of the AFO technology for water and wastewater pipeline condition assessment.

“An ultimate objective of this research is to build a foundation for integrating wire break detection, leak detection, and wall thickness detection analyses into one single interpretation system,” he said. “Utilizing these three capabilities in one interpretation system is a promising approach for pipeline nondestructive condition assessment technology.”

When Dr. Jung isn’t working to become one of the best underground infrastructure researchers, he’s unwinding on the golf course. He particularly liked Mill Creek’s course.

“I searched the web and found that parks in Youngstown, including Mill Creek Park, are one of the best in northeast,” Dr. Jung said. “I learned golf two years ago, and I am still a beginner.”
