Research Facilities


The Department aims to provide advanced teaching and research accommodation for both undergraduates and postgraduates in state-of-the-art laboratories and facilities.

Other Information


For full-time UGC quota PhD admission, preference will be given to applicants who apply for the Hong Kong PhD Fellowship Scheme, for which the application period starts in early September each year. All research postgraduate applicants are recommended to approach potential supervisors and preferably, put their names on the applications. For details, please refer to “Research Areas” or ME website > Academic Staff.

 

The Department has organised/co-organised a series of symposiums and international conferences to pursue knowledge through interactions among the world’s foremost scientists and scholars.  To further elevate its research quality and academic standing, the Department has also invited top-notch scholars to serve as visiting chair professors under the Distinguished Chair Professor Scheme. Learn more at Emeritus Professor, Visiting & Adjunct Staff.

 

The Department offers student exchange opportunities to enhance students’ global outlook, languages skills and personal development.  Every year, the Department arranges research attachments (from three to six months) for students to visit overseas universities with financial support.

 

With the aim of advancing research by exchanging knowledge and ideas within the field of Mechanical Engineering, the Department also provides additional financial support to research students to attend international conferences.
