Dr Cos Chiera holds a PhD in Mathematics from RMIT University, Australia, and continues to provide tutoring services as an Associate of RMIT for both mathematics and engineering courses. He has lectured at multiple higher education institutions across Victoria. In the late 1990s through to the early 2010s, Cos took time out from academia to work in the corporate world. Starting as a project manager in Y2K projects he worked his way up to Chief Operations Officer (COO), specialising in start-up companies and business triage. Nowadays Cos splits his time between consultancy work, academia, lifesaving (during the summer season) and his family. Indeed, his wife and two daughters provided much of the inspiration for this book. Of particular interest to Cos is the metric of 'Integrity', especially as it applies to the virtues of diligence and honour.
