Current Graduate Students
Zhenhong Lin (Ph.D candidate, expected to graduate in 2008)
Lin joined ITS-Davis in 2003.  He received his B.E. and M.S. degree from Tsinghua University in China.  By integrating his knowledge in hydrogen technology, economics, GIS, and dynamic system modeling, he developed an optimization model to provide decision support for smooth transition to a Hydrogen based transportation system.  This dissertation research has deepened existing understanding about the impacts of evolving technology, policy, and demand on hydrogen industry and the associated infrastructure needs.  A paper based on this dissertation work was awarded the best paper in "Strategic and Socioeconomic Analyses” at the 2nd World Congress of Young Scientists on Hydrogen Energy Systems (HySyDays 2007).  Lin has worked with several government agencies and energy consulting companies, and is now working at the California Air Resource Board.  [Email: zlin@ucdavis.edu]
Changzheng Liu (Ph.D candidate, expected to graduate in 2009)
Changzheng joined the doctoral program in Transportation in the Department of Civil and Environmental Engineering in 2004.  He has a M.S. degree from Tsinghua university in China.  Changzheng’s primary research interest and strength are on mathematical programming and algorithm design with applications in transportation and energy systems, particularly for problems involving decision making under uncertainties.  He has helped design and implement several decomposition algorithms to solve large scale stochastic network design problems.  Changzheng has led a project on seismic risk mitigation for highway networks.  He is currently contributing his stochastic modeling and computing skills to one of my projects on integrated bioenergy system design.  He has work experience at the Global Energy Systems, an energy consulting company.  He is interested in a research position after graduation.  [Email: czliu@ucdavis.edu]      
Yongxi (Eric) Huang (Ph.D candidate)
Yongxi joined the doctoral program in Civil and Environmental Engineering in 2005.  He received his M.S. degree at National University of Singapore.  Yongxi’s main interest is on designing robust and efficient bio-energy logistics systems.  His technical strength is on GIS data processing, visualization, and robust system modeling.  He is also students’ favorite TA in the introduction class to operations research.  Yongxi enjoys every job he has taken, but he is still in the process of figuring out what he really wants to do as a career.  [Email: yxhuang@ucdavis.edu]    
Chien-Wei Chen (Ph.D candidate)
Chien-Wei joined the doctoral program in Transportation Technology and Policy program at UC Davis in 2005.  He has a M.S. degree from Jiao-Tong University in Taiwan.  Chien-Wei is interested in network resilience and reliability theories.  He is currently carrying out research in designing reliable and cost-effective energy delivery network under natural hazards and malicious attacks.  [Email: scwchen@ucdavis.edu]    
Nathan Parker (Co-advised with Prof. Joan Ogden)
Nathan is currently a doctoral student in Transportation Technology and Policy Program.  He possesses unique breath and depth in mathematical modeling, energy technology, and bioenergy feedstock resources.  His master thesis on optimizing bio-hydrogen system was awarded the prestigious Council of University Transportation Centers’ 2007 Charley V. Wootan award, for the best Masters’ thesis in 2007 in the United States in the area of Transportation Planning and Policy.  He is a key player and the major driving force in several interdisciplinary bioenergy projects on Davis campus.  Nathan has a clear career goal in academia, and is already making great progress toward this goal.  [Email: ncparker@ucdavis.edu]      
Zheng Wan (Master student)
Zheng joined the master program in Transportation Technology and Policy program in 2007.  He is interested in transportation policy and port resource management in China.  [Email: mrwan@ucdavis.edu]
