I would like to express my greatest gratitude to my committee Elizabeth Belding, Rich Wolski, and Chandra Krintz for guiding me throughout my degree. You have invested countless hours in my education and helped shape me as a computer scientist. Elizabeth thank you in particular for years of meetings, advice, and support. Thanks to my coworkers and lab-mates, Nevena Golubovic, Morgan Vigil-Hayes, Daniel Iland, Paul Schmitt, Esther Showalter, and Mai EL-Hussein for support and the endless hours of fruitful discussion. Thank you for your professionalism and friendship. A special thanks to Vivek Adarsh and Udit Paul for the great company, fantastic ideas, and endless hours of field work. You made the hours of work go by in a flash. I am looking forward to all the amazing research you will produce in the coming years. In addition, thank you to local UCSB collaborators Lisa Han, Hannah Goodwin, Kristi Hocevar, and Pritha Narayanappa for collaborative work on freedom of Speech. None of this research would have been possible without many US and international collaborators. In particular, thank you to Jerrold Baca, Joseph Peralta, Kiss Abraham, and Zaya Nara for your time and resource investment. It was a pleasure to work with you. Thanks to many local partners, including the Southern California Tribal Chairmen's Association's Tribal Digital Village program, the Iipay Nation of Santa Ysabel, Santa Clara Pueblo, and Ohkay Owingeh. Thanks to Coal Oil Point Reserve for allowing us to utilize your space for our aerial testbed. Thanks to Kris Jaroensutasinee and Mullica Jaroensutasinee for hosting me at the Center for Excellence in Ecoinformatics at Walailak University during my Fulbright tenure iv and prior. Without your support I would not be where I am today. In addition, I would like to express gratitude to my PhD colleagues at Walailak who have worked with me, including Sirilak Chumkiew, Premrudee Noonsang, Siriwan Wongkoon, Wittaya Pheera, Uthai Kuhapong, and Puangrat Jinpon. Thank you to the Taiwan Forestry Research Institute, including Chau Chin Lin, Sheng-Shan Lu, and Yu-Huang Wang for a decade of collaborations on terrestrial sensor networks. Your group has been incredibly patient and supporting of my work from a fledgling undergraduate to a professional researcher. Thanks to Peter Arzberger for providing my first research opportunities and having faith in my abilities to grow into the person I am today. You initially pushed me to pursue a PhD, and taught me the skills needed to succeed. Thank you to Tony Fountain for advising me at CALIT2 during the transition period from undergraduate to graduate school. You taught me how to conduct research and grow collaborations. Thanks to Irina Artamonova for supporting me emotionally, financially and intellectu- ally. In addition to a great mom, she is a talented statistician who has been instrumental in my work. Thank you for always being there for me to catch me when I falter. Finally, and most importantly thank you to my life partner Sherri Lynn Conklin. She has been patient, supporting, encouraging, and absolutely key to all my work, including this dissertation. An accomplished academic herself, and a far better writer, she has spent hundreds of hours reading through drafts of my work and grant proposals. Thank you so much for always being there when I need you most.
