who provided me with guidance, encouragement, and a unique scientific perspective that provided me with the environment necessary for success. I am especially grateful for Dr. Diane Rohlman, my committee chair. This journey has not always been an easy one, but I am thankful for your commitment to me as your mentee and your dedication to helping me grow as a scientist in this field. With this came some tough conversations and difficult decisions, but I am eternally grateful for the woman, better yet, the Toxicologist, you've pushed me to become. Thank you, Diane. I would also like to thank Dr. Ludewig, the Director of Graduate Students for the Human Toxicology program. I want to say thank you for all of the times you've allowed me in your office for laughter, encouragement and sometimes tears. Though my stint in Iowa has brought about some difficult situations, thank you for always encouraging me to see the bigger picture. I want to thank my officemates, Kate, Josie and Maya. I did not know what to expect when I moved into Joel's old office space, but I am grateful that we all crossed paths. Maya, you have truly become a part of my support system and I am thankful for all of the wisdom, the encouragement, and the bad jokes we've shared these last few years. To those who became a part of my village in Iowa, I am eternally grateful. Rondine, Ashlei, Taimyr, Thapelo, Victoria, Roseina, Ashley, Zana, and every other amazing woman I have crossed paths with while in Iowa, thank you. Often times it is difficult to articulate the double consciousness we live while navigating academia as Black women and having you all in my circle who just get it, made Iowa that much more v amazing. Thank you for all of the support, the late-nights, the 'we in this together' talks, and for each of you being a light in your respective fields and across the University of Iowa's campus. I would like to especially thank Ashlei, Taimyr and Rondine. I am not sure I would have survived graduate school without you three amazing and brilliant women. Thank you. To my lifelong friends/sisters, Charda, Toni, Sara, Ebony, Courtney, Minisha, and Alania, thank you for always supporting me no matter how near or far our paths take us. From the "I need to get away" trips to the "let's just sit in the house and do nothing" adventures, you women have literally become a cornerstone for me. Thank you for always pushing me, showing up (and out haha!), and being the genuine friends, I did not know I needed but am grateful I found. Lastly, I'd like to thank my family. To my older brother, thank you for all of the wise words you've shared over the years. I know if I ever need a laugh, that you will always be there to change my frown into a smile. To my younger siblings, thank you for being my biggest fans. You all are my motivation for continuing to push myself further and farther each day. To my mother, one of the strongest women I know, through all of her life experiences she made sure that each of her five children never stopped believing that they could achieve...
