Doren, Ph.D. Interim Vice Provost for Graduate and Professional Education ACKNOWLEDGMENTS Writing a thesis is hard work, and I have a great deal of people to thank for the help, patience, and support that has kept me going. First, thank you to Dr. Paul Brewer, the chairman of my committee – this project would not have been possible without your patience, guidance, and thoughtful input. Your knowledge and expertise helped me grow my project from the ground up, and for that I am incredibly grateful. Thank you, also, to the rest of my committee: Dr. James Angelini and Dr. Danielle Catona. Your help, from our very first meeting, nurtured this project and gave me a solid foundation for success; I am grateful for both your time and wisdom. I would also like to thank my family and friends for their constant love and compassion. Your ability to cope with my outbursts of deadline stress, mid-project anxiety, and general senioritis made this project possible, and I am so glad you listened to my stress-driven rants, even though you might not have understood what exactly, I was so stressed about. iii TABLE OF CONTENTS LIST OF TABLES

That chunk of DNA, known as Crispr, has become an invaluable tool for genetic editing, with its use by scientists quickly overtaking both other common gene-editing technologies. Innovations using Crispr, from modifying mosquitos to prevent malaria, to creating drought-resistant crops, to the birth of the very first edited babies – twins – in late 2018, have made headlines in news outlets around the world.
