To all my colleagues and customers who have worked with me during the past 14 years in the field of network science in different companies, countries, and industries. It is hard to name all of them, but I would like to give a special thanks to some individuals who were extremely important throughout this journey.

A special thanks to Manoj Chari, Ed Hughes, Rob Pratt, Matthew Galati, Brandon Reese, and Natalia Summerville from SAS US; and Falko Schulz from SAS Australia. My thanks is especially for those who created such amazing network science tool, and others, working with me on such awesome projects in the network science field. I give a double thanks to Matt for doing both.

As everything is connected, and different knowledge can always be combined, I feel compelled to thank my colleagues from SAS Education, where I learned so much in many other fields of analytics. I thank you all. However, I would like to name a few who I have worked with closely in teaching and course development. Thanks to Cat Truxillo, Chip Wells, Jeff Thompson, Robert Blanchard, Jay Laramore, Terry Woodfield, Mike Patetta, Peter Christie, and Danny Modlin.

I am grateful to have been advised and supervised by the brilliant minds in academia. A very special thanks to Luciana Ferraz Thomé from Universidade Federal Fluminense; Alexandre G. Evsukoff and Nelson F. F. Ebecken from Universidade Federal do Rio de Janeiro; Vladas Sidoravicius from Instituto Nacional de Matemática Pura e Aplicada; Markus Helfert from Dublin City University; Kavé Salamatian from Université de Savoie; Bart Baesens from KU Leuven; and Moacyr Silva from Fundação Getúlio Vargas.
