Perseverance is what makes the impossible possible, the possible probable and the probable realized Robert Half 2 Acknowledgements First, I would like to thank all the members of the jury: Laurent Le Cam, Dimitris Xirodimas, Mounira Chelbi-Alix, Robert Weil and Frederic Devaux who, despite a very busy schedule, took the time to take part in this thesis defense jury. I would like to thank Anne Dejean for giving me the opportunity to be part of her research team since my master internship, for giving me the chance to meet very interesting people, and for providing me with many opportunities. Thank you for the trust you put in me to carry out this complicated project as well as for providing the best working conditions, and collaborations to realize it. Thank you for all the things I was able to learn from you, your team and the world of science in which we are involved. I would like to thank the entire ONO team for their support during these past few, short, years: Thank you to the past members: Adrien, the basketball player from room 306, and Pierre for your help, advices and good sense of humor; Yoon Ra for your kindness and zeness; Ricardo for bringing a little bit of Mexican spirit to the lab; Louise-Mary for all your help with the administrative paperwork and Sophie aka Fofi, aka “la personne la plus désagréable du labo, mais qui en vrai, est plus ou moins relativement super sympa”. A big thank for your help and support to you and all the people I might have met during these years.
