I would also like to express my appreciation and gratitude to my husband, Dr. Matt Cave. Without his love, devotion, compassion, respect, encouragement, willingness to pick up the slack at home, and patience, I would not have achieved the success I have to-date. Thank you to William and Sam Cave for eating my hastily cooked dinners, and respecting my need for quiet. Lastly, I wish to thank my son, Nikolai Goshko, for his kindness, respect, patience, and understanding, and recognize his personal sacrifices to help see me through the PhD journey.
