PhD in Mechanical Engineering (Energy Technology Concentration)

Research Foci

The Department's research concentrates on energy and environmental engineering, mechanics and materials, and mechatronics and manufacturing.

Solid Mechanics and Dynamics

These are two of the fundamental pillars of Mechanics research. The Department has a diverse faculty with expertise in these fields. Research activities range from applied to theoretical problems and have a marked multidisciplinary nature. They involve applied mathematics, solid mechanics, nonlinear dynamics, computations, solid-state physics, material science, and experiments for various kinds of solid materials/systems and mechanical behaviors. Faculty members work on problems of both static and dynamic natures with different types of evolutions. These problems also involve multi-field coupling on different scales of time and length, from micro-second to longtime creep processes and from a very small carbon nanotube or a cell to macroscopic scale composite materials and electromechanical devices/systems.

Materials Technology

Materials engineering focuses on characterizing and processing new materials, developing processes for controlling their properties and their economical production, generating engineering data necessary for design, and predicting the performance of products. Research topics include smart materials, biomaterials, thin films, composites, fracture and fatigue, residual life assessment, materials issues in electronic packaging, materials recycling, plastics flow in injection molding, advanced powder processing, desktop manufacturing, and instrumentation and measurement techniques.

Design and Manufacturing Automation

These elements lie at the heart of mechanical engineering in which engineers conceive, design, build, and test innovative solutions to "real world" problems. Research is being conducted in the areas of geometric modeling, intelligent design and manufacturing process optimization, in-process monitoring and control of manufacturing processes, servosystem control, robotics, mechatronics, prime-mover system control, sensor technology, and measurement techniques, and bio-medical systems design and manufacturing.

Microsystems and Precision Engineering

Micro-Electro-Mechanical Systems (MEMS) is a multidisciplinary research field that has been making a great impact on our daily life, including various micro sensors used in personal electronics, transportation, communication, and biomedical diagnostics. Fundamental and applied research work is being conducted in this area. Basic micro/nanomechanics, such as fluid and solid mechanics, heat transfer, and materials problems unique to micro/nanomechanical systems are studied. New ideas to produce microsystems for energy, biomedicine and nanomaterials, microsensors, and microactuators are explored. Technology issues related to the micro/nanofabrication of these devices are being addressed.

Energy Technology Concentration

Energy has been considered a core research area within the broadly-based disciplines of environmental science and technology. It is one of the most salient emerging disciplines amongst many in the fields of engineering, science, and social science. Energy Technology research covers many areas, including sustainable technology, conventional technology, and energy efficiency, and conservation. The interdisciplinary postgraduate research program in Energy Technology in the School of Engineering at the Hong Kong University of Science and Technology provides long-term support to our ongoing educational training and fast-developing research in technology in general.

Due to the multi-disciplinary nature of Energy Technology, research and training in the field are integrated with different disciplines so that students can be equipped with the necessary knowledge and experience.
