This book is a special edition, compiled for to the MSc Course Research Methodologies as taught at the Faculty of Aerospace Engineering at Delft University of Technology. It is a compilation of useful chapters from several sources on how to structure, set up, carry out and write up your (thesis) research to aid you in writing your research plan. Next to that it acts as a companion during your thesis research. After introducing you to the philosophy of scientific research, subsequent chapters each contribute to the different phases of your research. The book uniquely allows for the often multi- or interdisciplinary research many of you carry out, based on the established Dutch university tradition of (semi-)independent student research, creating a thread through the process for you to follow. This edition is a collection of chapters from An Introduction to Interdisciplinary Research (2016), edited by Steph Menken and Machiel Keestra, and Academic Skills for Interdisciplinary Studies. Revised edition (2019), by Koen van der Gaast, Laura Koenders and Ger Post, published by Amsterdam University Press.
