Jaejin Jang, Ph.D.

Associate Professor
Industrial And Manufacturing Engr

Dr. Jang’s focus is on improving the profit of an organization through improved efficiency in production and service. This includes research on timing between systems as well as determining why identical machines have widely different performance outputs. He’s also working on supply chain and facility planning issues, as well as how organizations can minimize downtime due to machine malfunctions.
