After obtaining a Bachelor of Engineering in a 5 year program offering a mixture of engineering and chemistry courses in 1989, Prof. Shamey worked in textile mills (dyeing and finishing industry) for three years in various capacities from process engineer to section manager.
Prof. Shamey obtained a Master of Science degree in Dyeing and Finishing (with Distinction) jointly from the “Colour Chemistry Department” and “School of Textile Industries” of Leeds University in 1993 working on a colour science project under the direction of Dr. James. H. Nobbs at the Colour Chemistry Dept. of Leeds University.
He continued to work with Dr. Nobbs for four years during his PhD program between 1993 and 1997. His work was focused on modelling and real time control of dye concentration in a dyebath. After completing his PhD he worked as a post doctoral research associate at the Colour Chemistry Department of Leeds University on an industrial project sponsored by Unilever between 1997 and 1998.
Prof. Shamey joined Heriot-Watt University in Galashiels (Scotland) in 1998, as Lecturer (Assistant Professor) in Dyeing, Printing and Finishing where he established the Automation and Novel Coloration Research Group. He was nominated for a University wide Excellence in Teaching Award in 2002 and was specially commended.
In 2003, Prof. Shamey joined the TECS Dept. at NCSU and served as Polymer and Color Chemistry (PCC) program director since 2009 till 2018.
Prof. Shamey is the President Elect of Inter-Society Color Council (USA) and a Fellow of the Society of Dyers and Colourists and a Chartered Colourist (CCol) (UK). He is also an honorary professor at Tianjin Polytechnic University (China).
Prof. 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 free style Olympic wrestling for several years. He enjoys playing badminton and basketball in his spare time as well as traveling, learning new languages, and classical guitar.

- Color Difference
- Color Perception especially blackness, whiteness, grays, unique hues
- Measurement and analysis of complex colored patterns
Ten PhD and five Masters projects have been completed in these areas. Four 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 expert 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.
- Dye Application and Textile Chemistry
- Dyeing of Polyolefins (Polypropylene, PE)
- The Effect of Colorants on Ageing and Degradation of Fibers
Five 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 and compounds such as nano TiO2 in fiber.
