This thesis is dedicated to my brother, Adam Batschelet, whose persistent support and guidance inspired me to apply to graduate school. I owe all of my success in graduate school, including this thesis, to him. I'd also like to dedicate this to my parents, Allen and Terri Batschelet, whose endless encouragement, advice and support motivated my success. I'd also like to dedicate this thesis to my major professor, Tracy Lucht, for her generous support, insightful guidance and the many cups of coffee over which this thesis was discussed. Her mentorship and friendship shaped my experience at Iowa State, and piqued my passion for research, for which I am truly thankful.
