This handbook is the result of many useful and inspiring conversations with students, faculty, and staff at Thiel College. Thank you for your generosity. We are grateful to DHI Founder Dr. Curt Thompson for his vision for the DHI Thesis and to former DHI Director Dr. Matthew Morgan for carrying on that tradition. Special thanks to Dr. George Branch-Trevathan for his work shaping the DHI Thesis course over the last several years, making it a rewarding and positive experience for our students. His insights and ideas are found throughout this handbook.
