ACKNOWLEDGMENTS I would like to start by addressing my sincerely and gratitude for several people who have supported me during my PhD, and all those who contributed to the successful completion of this work. I would like to thank all the jury members for taking the time to be part of the defense and assess of this work. I would like to thank Professor Armand Maul for his kindness in guiding my path in the implementation of statistics, Emmanuelle Montarg̀s-Pelletier for her support, expertise, collaboration and helpful feedback during the course of this project. My sincere gratitude to my supervisors, Christophe Merlin, Xavier Bellanger and Laurence Mathieu for their invaluable advice, guidance and encouragement during these years. I'm very thankful for their support during the hardest moments of my life. My sincere thanks also goes to all members of the LCPME MIC team with special thanks to Hélène, Sylvie, David, Edith, Audrey, Maryse, and to Lorine and Arthur, master students, for their collaboration in this work. I thank to the best officemates, Anaïs, Véronica and Zineb, for their friendship, for all the fun (in and outside the lab), and for their encouragement in the difficult moments. Also, I would like to acknowledge the financial support from the different institutions: the National Council on Science and Technology of Mexico (CONACYT) scholarship (reference 410720), the Agence Nationale de la Recherche ANR (MOBISED project, ANR-14-CE01-0019), the Rhin-Meuse Water Agency (AERM project QUALIORNE), the LTSER-France, and the Lorraine Region through the research network of Zone Atelier Moselle (ZAM). I want to thank ALL my latino-friends who became my family and who made these years away from home, less difficult and very enjoyable, especially to team Mexico represented by Mariana, Carmen. Piña, Marcela, Bibiana, Yara (My favorite mexas in Germany). Team cuba, Claudia, Alejandro, Alexis, Mariana (Brazil) for all the moments we spent together, the shared meals, the dancing nights… I really going to miss you all guys. Last but not least, I would like to express my profound gratitude to my family and to Gonzalo for their love and constant support, for being my strength when I was weak, without them this wouldn’t be possible. I dedicate this thesis to my parents, to my brother César, to my nieces and my nephew, my boyfriend and to my brother Eric, who rests in peace, he is always in my thoughts and in my heart. Gracias familia, los amo con todo mi corazón, ustedes son el viento que impulsa mis alas.
