**Meet the editor**

Professor Denis A. Coelho's main teaching contribution has been stimulating the formation and initial operation of graduate courses in Industrial Design and MA in Industrial Design Engineering at UBI. He develops scientific activity within product design methodologies and has also conducted research in the field of ergonomic design and human requirements on technology,

developed extensively in his doctoral work. Professor Coelho collaborates with several international research institutions in the areas of product design and ergonomics. The key area of his scientific activity is focused on the Human Interface located between technology and humans, which is characterized by an interdisciplinary nature, with technical and technological bias favouring an ergonomic perspective. His scientific activity also extends to product design methodologies, normalization applied to industrial management systems and production strategy in international networks. He is editor in chief of the International Journal of Human Factors and Ergonomics.
