LEBOISNE 2 Mabelle SAYAH PhD Thesis Acknowledgment With these few thesis chapters, I am closing a much more important chapter. The chapter of my life that I was aiming for since my first day in university. With this work I will complete my dream of holding a PhD in a subject that interests me a great deal. However, I really need to thank each and every person that helped me reach this point in my life: by helping me morally, financially or academically. This is the end of one milestone for me but it took the help of many to be here. Without each one of you I would not have achieved this and for that I am very grateful. I would like to thank Mr. Adel Satel, Group Chief Risk officer at Bank Audi for believing in me and granting me the opportunity to undertake my PhD. For your vision and kindness, and for making these three years possible, I am sincerely thankful. My internship at Bank Audi involved working with two different teams: the group market and credit risk teams. I was really lucky to work under the supervision of both Mazen Hamdoun and Elias Abou Sleiman. Their ex- perience and know-how added the feasibility aspect to my work and made me gain lots of knowledge I would have never gotten otherwise. Mazen for your patience and easily-grasped explanations, Elias for your numerous insights and the opportunities you gave me for a wider exposure, I am forever indebted. To their respective teams, especially Rudy, Joyce, Remy and Hana: To you I owe a lot, not only have you increased my professional baggage but getting to know you individually was a great pleasure, gaining a good friend in each. Dear Abdallah, you were the biggest positive mystery in these previous three years. I was really overwhelmed by your kindness and unconditional help. With your great experience, academically and professionally, you were the mentor of the last part of my work. I will never be able to repay you your helpful gesture and permanent moral support. Another very important yet unknown pillar of this thesis is Elias Karam. You have been my last resort in so many situations these last years. I was always hesitant to call you and bother you with my work however you were always more than helpful, checking constantly and making sure I pass my problems. You really are a very genuine and honest person. Thank you for your help in the work, thank you for being a dear friend these last years, thank you for the long deep discussions we had about almost everything... Best of luck for everything in your life, you sincerely deserve it. Working within the Risk team in Bank Audi was really a pleasure. Each one of the team members adds a new unique flavor to working there. Patrick for believing in my goal since day one, Karim for your insights and helpful tips, Philippe for your innovative ideas and endless challenges. Lama, Maya, Odette, Michel, Gerges, Youssef, Solange, Joanna, Noura, Nisrine, Madonna, Nancy, Tony, Charbel, Raja, Joe, Bryan, Nathalie, Naoum ... the list is endless, thank you dear friends for making this journey worth it. A special thank you for the Lebanese National Council For Scientific Research (CNRS) and them funding the research. Your hard work makes it possible to still believe in science and its development in our country. Thank you for providing me with the initial weapon to go into this fight and get my degree. I would also like to thank all the jury members, especially Prof. Laurent, Prof. Bessis and Prof. Haselmann for taking the time to carefully read my work. Your remarks and suggestions helped me greatly improve the over- all outcome of this thesis. To Rami, Tony and Gihane of the Mathematics department of the USJ, Lebanon. Each one of you had his im- portant role to play in my journey. To Tony that from day 1 grant me the hope that a PhD was possible and guided me to the adequate master’s memoire´ in order to achieve this dream, I thank you. To Rami that very kindly accepted to supervise my work and helped me find a funding for my studies, I am very grateful. To Gihane that never stopped giving me advice and believed in me to give few courses in my university, I really thank you too. 3 Mabelle SAYAH PhD Thesis To Christian, my supervisor, I would like to express my most sincere gratitude. I say it with great conviction: If you were not my supervisor, I would not have achieved or completed the work I am presenting today. For your patience, your great sense of humor, your optimistic but realistic point of view I am very thankful. For all those days that started with an e-mail at 7 a.m. and failed to finish before 10 p.m. I thank you! For all the times I had those panic attacks and you were there to reassure me I thank you! I wish you a very successful and happy life for you and your family. Five out of seven days a week I spent it in the SAF laboratory and I could never imagine how all this time would have passed without the people in this place. I am very lucky to have met everybody here. Ines, Saker, Thibaud, Claire, Thomas thank you for the good times and best of luck for your journey. A special greeting to Jean and Antoine, I know that I would have never survived all this office time without you guys. For every delicious lunch we had at the resto U, for every beer we drunk at the Ninkazi and every birthday we celebrated together I thank you and I really hope that we stay in touch because you are both exceptional. Julie you were also miss sunshine that always was optimistic about almost everything, and that was more than helpful, Thanks and may you able to achieve all your dreams. Gwladys, I was really happy to get to know you these past years, you are one of the most kind hearted persons that I have ever met, may you have all the success and happiness that you dream of.
