I would like to thank my coauthors, colleagues, and students who have helped me learn and explore this exciting topic. Special thanks goes to my wife Kathy, and daughters Grace and Tate, for their love, encouragement, and support.
I would like to thank my coauthors and former colleagues at InterContinental Hotels Group and Predictix for offering me the opportunity to work with them. I would also like to acknowledge the debt I owe to my family—I have become who I am because of them.
To all those who inspired and believed in us—we are grateful for all your support.
