Acknowledgements

I’d like to begin by thanking my advisor, Dr. Richard Stern. His support – financial, intellectual and moral – has carried me through graduate school. His belief in me has bolstered my own resolve and sustained my efforts. Most importantly, though, he has been a mentor and role model, one worthy of my respect and admiration; truly, that is all anyone can ask. I’d also like to thank Dr. Bhiksha Raj and Dr. Rita Singh for numerous discussions, ideas, pointers, lessons and general pieces of advice given throughout my time in graduate school. Their academic guidance and moral support have been essential and are greatly appreciated. If for no other reason, I value my time at Carnegie Mellon for the opportunity it provided to befriend and learn from these individuals. There are many others who have helped me get to this point – teachers, professors, relatives and friends who have enlightened, inspired, encouraged, helped or otherwise touched me over the years. Even if I have failed to adequately express my gratitude to them, it is felt wholeheartedly. There are too many to mention, but I would like to thank a few by name. I thank my committee members, Dr. Bhagavatula and Dr
