Acknowledgments

First and foremost, I would like to praise and thank Allah SWT, the compassionate, the almighty, the most merciful, who has granted me countless blessings, knowledge, and opportunities. Without the will of Allah SWT, none of this would be possible.

I would like to thank my parents for getting me started on my journey, giving me the opportunity for a great education, allowing me to realize my own potential, and giving me the freedom to choose my career path. Thanks Dad (Masood Ahmad Nisar) and Mom (Saeeda Perveen); you both have always supported me and encouraged me in everything I have ever done. You both have worked extremely hard all your life to give me the life I wanted.

I would like to thank my caring, loving, and supportive ...
