Along the direction of RISUD by leading to the conduct of cutting-edge research into solutions to problems generated by high-density urban development, a scheme named Interdisciplinary Research Scheme is launched to provide funding for the encouragement of research collaborations among different departments and faculties, and among various Research Institutes (RIs) in PolyU. The research topics should be interdisciplinary aimed to proposing advance agendas for sustainable development. Applicants should clearly identify external sources of funding and specify a timeline for proposal submission that will be pursued as a result of this internal funding.
