Election Investigations Guidebook lessons and peer reviewed recommendations, and writers and editors at IFES who helped finalize this manuscript. Over the years, so many people have worked on this book that I do not have the space needed to name them all. However, I would like to acknowledge and thank a few key individuals. Early in the process Ena Dakanic and Emily Lippolis helped collect data, conduct research and draft sections that form the foundation of this publication. As the publication started to take form, Typhaine Roblot, Heather Szilagyi and Alexandra Brown contributed hours of time editing, researching outstanding questions, and structuring the findings in a user-friendly format. Erica Shein’s editing greatly increased the clarity and thoughtfulness of the work, which was not an easy task considering the subject matter and length of this publication. Similarly, I want to thank Manuel Wally, George Carmona and Sir Hugh Williams for their thorough and thoughtful peer review and Lorenzo Córdova Vianello for providing a thought-provoking foreword that provides a practitioner’s perspective to the subject and helps to frame and introduce our work. Finally, I cannot thank enough my co-author Katherine Ellena who always challenges my assumptions, pushes my thinking on these subjects, provides great insights into our work, brings a deep interest in and enthusiasm for the subject matter and ensures that our publications are practically-focused to ensure the impact of our work on the ground.
