Research Ambitions
My overall area of interest consists of defining and deploying evaluation protocols for technology innovations in the built environment. I intend to continue addressing relevant problems in the construction industry, such as the uncertainty of adopting innovative technologies which are intended to improve energy efficiency and construction processes. My focus will be on innovative technologies for sustainable construction, which concentrates on the feasibility of state-of-art fuel cells or net-zero bioenergy alternatives for residential construction, as well uses for material selection and energy system retrofitting.

Research Ambitions

Digital models are becoming the basis for design, analysis, simulation, construction planning, construction execution, operation and maintenance. As various tools and technology for virtual design and construction mature, it is important to integrate them with existing processes and work flows in the industry. There is a need for addressing seamless data exchange between users and systems, in what is called interoperability. With the goal of an open-BIM framework catering to the entire lifecycle of building and infrastructure projects in mind, I envision a three-tiered approach, namely fundamental, applied and socio-economic, towards conducting my research.

At one end of the spectrum, I plan to direct future research in resolving this interoperability problem in design, engineering and construction at a fundamental level by specifying new methods and standards. An example for such fundamental research is an automated information exchange protocol using Industry Foundation Classes (IFC). In terms of applied research, I plan to focus on developing and integrating new technologies and solutions for virtual design and construction. Automated rapid prototyping of a rich and detailed information model from spatial data, for as-built control and facility management are examples of applied research I intend to pursue in the future. Improvements in interoperability research and better work flows in industry will lead to savings in the form of reduced wastage of resources and rework.

I envision an overall improvement in the quality of products for construction community with the help of new computer aided design tools, new special purpose applications, and innovative processes, which will transfer to new lines of education. The open-BIM framework, which is my long term interest, will lead to disseminating the benefits of research to the entire industry, for example, developing an integrated dashboard for building performance monitoring to achieve a better LEED rating, thereby, improving the socio-economic fabric of society leading to sustainable development.
