Dr David D Rodrigues

Postdoctoral Research Assistant

Profile

He has undertaken a degree in Technological Chemistry at the Faculty of Sciences of the University of Lisbon (FCUL). After graduation, he has worked at the Organic Materials Division (NMO) at the Portuguese National Laboratory for Civil Engineering (LNEC) in the areas of research and development of polymeric materials (plastics, fibre reinforced polymers, paints, varnishes and other organic coatings) for structural, aesthetics and protection applications, through physical, chemical, mechanical and rheological characterization, and evaluation of the performance and durability of materials). Latter, he worked in the paint industry has a chemical engineer at HEMPEL – Portugal as responsible for quality control of the production line, as well, making direct contact with domestic and foreign clients, being responsible for the acquisition and maintenance of laboratory equipment and for management and development of pigment formulations. Over some years, he was at Timber Structures Division (LNEC) in the development of repair and reinforcement of timber structures, through adhesives and combination with other materials, e.g. fibre reinforced polymers and concrete. During that time, he performed an MSc at Faculty of Sciences of the University of Lisbon (DQB/FCUL) and National Laboratory for Civil Engineering (NEM/LNEC), entitled "Bonded Joints for the Rehabilitation of Heritage Building. Methodology to Evaluate and Select Adhesives Used in the Repair of Ancient Timber Structures. Lately, he has been involved in several projects involving adhesive bonding and composites at the Joining Technology Research Centre (JTRC/Oxford Brookes University) through surface analysis and surface treatments applied in different materials and experimental methods. He has also conducted a PhD entitled “Improved adhesion to Boron Carbide Using Organo-silanes” in collaboration with Advance Materials Group (AMG/Harwell Campus) of the Science and Technology Facilities Council (STFC).
