Renzo Shamey
Bio
Prof. Shamey served as the President of Inter-Society Color Council (USA, 2018-2022). He received the Fellowship of the Society of Dyers and Colourists and a Chartered Colourist (CCol) in the UK in 2010. He was selected a University Faculty Scholar at NCSU in 2014. He is an honorary professor at Tianjin Polytechnic University (China). Prof. Shamey is the co-author of several books and book chapters, most notably, “Modeling, Simulation and Control of the Dyeing Process”, and “Pioneers of Color Science” and is the editor of the 2nd edition of the “Encyclopedia of Color Science and Technology”. During his graduate studies Renzo Shamey was elected the Academic Secretary of the United Kingdom National Postgraduate Committee (NPC) as well as the President of the Postgraduate Representative Council (PGRC) of Leeds University between 1995-1998. He was a state champion in freestyle wrestling for several years in his school years. He enjoys playing badminton, traveling, and learning new languages. Fifteen PhD and five Masters projects have been completed in these areas. Three PhD projects are currently underway on perception & modelling of texture, and characterization of color of complex patterns using digital cameras. Other projects involve assessment of color difference formulae and development of visual datasets. Several PhD projects have been completed in this field. The current work focuses on the development of deep learning approaches and comprehensive AI systems to troubleshoot dyeing/printing problems. Other areas involve the examination of the effect of various parameters in real time on individual dyes in a dye admixture. Several PhD projects have been completed in these fields. Works of interest include exploring novel techniques to dye polyolefins, as well as the study of photodegradation of fibers as a result of inclusion of dyes in fiber.
