Dr. Zugang (Leo) Liu

Dr. Liu is a Professor of Business Administration at the Pennsylvania State University Hazleton Campus. He received his Ph.D. in Business Administration with a concentration in Management Science and a minor in Computer Science from the University of Massachusetts Amherst in May 2008.

He received a BS in Civil Engineering from Tsinghua University, China, and an MS in Transportation Engineering from the University of Massachusetts Amherst.

His research interests include: supply chain networks, transportation networks, telecommunication networks, electric power networks as well as financial networks. In particular, he studies the dynamics of such networks and their interrelationships, along with risk management.

In 2005-2006 Leo was President of the UMass Amherst INFORMS Student Chapter. Previously, he was the webmaster for the chapter and assumed this task again in late Spring 2007. In 2007 and in 2008, Leo received an Outstanding Service Award from the UMass Amherst INFORMS Student Chapter.

In 2008, Dr. Liu was elected to Beta Gamma Sigma, the Business Honor Society.

He was recognized for his research with an award from Penn State Hazleton.
