ACKNOWLEDGEMENTS
Foremost, I would like to express my sincere gratitude to my promoter Prof. Maurice Moens, for the constant support of my Ph.D. study and research, for his motivation, and for sharing with me his immense wealth of knowledge. I had the unique privilege of being his master and Ph.D. student. The knowledge acquired is highly appreciated and valued, and now constitutes a strong foundation for my future achievements and success. Also, I would like to thank his wife Mrs. Monique for her kindness.
I am profoundly grateful to my co-promoter Prof. Nicole Viaene for her supervision (including strong support for my scientific writing skills), her kindness, great ideas, and patience. I thank her for all the valuable time and effort she generously offered to me. Warm regards for all your family members Patrick, Nuria, and Robin.
I also wish to thank Prof. Luc Tirry for his help, encouragement and support during my Ph.D. research and administration issues. Thanks so much for your smiley disposition which, combined with your care and concern, was always very reassuring!
My profound gratitude goes to Dr Julie Nicol who guided me during both the MSc and Ph.D. scholarships and has been a role model throughout my research career. She provided
