Research Interests:
1. Colour Science and Technology:
- Color Difference
- Measurement and analysis of achromatic objects
- Color Perception

Two PhD projects have been completed in this field. The current work is to further the understanding of the effect of flow and dispersion factor on dye uniformity and the assessment of the effect of various parameters in real time on individual dyes within a dye admixture. The development of expert system software to troubleshoot dyeing/printing problems is also being pursued.
3. Coloration and Dye Application and Textile Chemistry

Biography:
|
I got my first degree in a 5 year program offering a mix of engineering and chemistry courses entitled Textile & Fibre Chemistry Engineering in 1989. I then worked in textile mills (dyeing and finishing industry) for three years in various capacities from process engineer to section manager.
I decided to continue my higher education and enrolled in a Masters program in Dyeing and Finishing at Leeds University. I got my MSc with Distinction, from the "School of Textile Industries" and the "Colour Chemistry Department" of Leeds University in 1993. My master's thesis was on a colour science project.
I enjoyed colour science so much that I decided to continue towards a doctoral degree. I worked with Dr. James Nobbs at Colour Chemistry Dept of Leeds University for four years and got a PhD in 1997. My work was focused on modelling and measuring dye concentration in a dyebath in real time.
I was also involved in student activities and was elected the Academic Secretary of United Kingdom National Postgraduate Committee (NPC) as well as the President of the Postgraduate Representative Council (PGRC) of Leeds University between 1995-1998.
I worked as a post doctoral research associate in Colour Chemistry Department at Leeds University on an industrial project for the Unilever for about a year after my PhD.
I obtained a Chartered Colourist (CCol) status in 2000 from the Society of Dyers and Colourists in the UK.
I joined Heriot-Watt University in Galashiels (Scotland) in1998, as Lecturer (Assistant Professor) in Dyeing, Printing and Finishing. I then established and led the Automation and Novel Coloration Research Group at Heriot-Watt University for five years.
I was nominated for the Excellence in Teaching Award at Heriot-Watt University in 2002 and was specially commended.
In 2003, I joined the Polymer and Color Chemistry (PCC) program in TECS, CoT at North Carolina State University. Although I supervised some of my graduate students in the UK until 2006.
On a personal level I love traveling, learning new languages, sports (I was a free style wrestling champion for several years) badminton, hiking and music especially classical guitar.
