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.
