RESEARCH CLUSTERS
Energy and Sustainability
Interdisciplinary research on sustainable energy solutions, policy frameworks, and green technologies to combat climate change.
Fundamental and Applied Hydraulics and Hydrology
"Hydraulics and ecohydrology of rivers (including ephemeral streams) and Environmental pollution assessment and mitigation are the key domains in this group. Study areas cover all types of land uses: pristine, rural to urban. This group has collaborations with the Institute of Mountain Hazards and Environment - Chinese Academy of Sciences, Irrigation Department, Sichuan University, and Saitama University.
Areas: Solving real-world problems of lotic and lentic waters and contributing to the fundamental understanding of lotic and lentic waters and their interaction with land/catchment "
Infrastructures, Project Management, Digital Transformation and Engineering Economics
"The built environment is prevalent for living and working. SIPM is a multi-disciplinary research group looking to identify, articulate and address the challenges faced by the construction industry and built environment. The research group works across various subject areas to identify how we design, deliver, and utilise built environment assets and infrastructure differently, considering challenges that impact both locally and globally.
Research group work covers infrastructure, project management, digital transformation, and engineering economics to address wider questions of how we create a resilient infrastructure and built environment in the face of local & global changes. New ideas and approaches require new skills for the construction industry; we work with construction companies to look at new delivery modes and support the development of the professions to meet these new requirements.
The research group signifies the convolution of the questions posed for the construction industry and recognises that for research to have an impact, it must be driven by collaboration with all stakeholders to improve the well-being of citizens, ensuring that buildings and infrastructure can meet current and future needs.
Areas: Feasibility of projects, Real estate Economics, Project management, Dispute Resolution and arbitration, Digital Transformation - BIM, Digital Twin"
Advanced AI Applications in Engineering
"The ""Advanced AI Applications in Engineering"" research group focuses on integrating cutting-edge artificial intelligence techniques across various engineering fields, including electrical and electronics, telecommunications, civil, mechanical, mechatronics, and biomedical engineering. The group aims to address complex real-world challenges by applying AI to optimize system performance, enhance energy efficiency, and improve automation.
Key areas of research include AI-driven system design, signal processing, smart infrastructure, autonomous systems, biomedical diagnostics, and intelligent manufacturing. Through interdisciplinary collaboration, the group seeks to advance AI-driven innovations that contribute to smarter, more resilient, and efficient engineering solutions."
