Yung-Cheng (Rex) Lai

Graduated: 2005 - M.S.; 2008 - PhD

Education

Mr. Lai received his PhD degree in the Civil & Environmental Engineering Department at the University of Illinois at Urbana-Champaign in May of 2008. He received his BS at National Taiwan University in 2002 and MS at University of Illinois in 2004.

Professional Interests

His research dealt with various aspects of train efficiency and railway capacity analysis. He explored options for improving the energy efficiency of intermodal freight trains and developing a model to optimize its loading pattern. For capacity analysis, his work investigated what the impact on capacity is while operating passenger trains on a freight railroad. The goal was to determine the characteristics of signaling systems that will allow passenger trains to operate while minimizing interference with freight operating capacity.

Ph.D. Dissertation:
