Personal Note.
I express sincere gratitude to my wife, parents, sister, and the rest of my family for their steadfast support and to academic mentors throughout my academic journey for their invaluable guidance.
I wish to extend profound appreciation to Professor Francisco Flores for his role in enlisting me as an undergraduate research assistant at Universidad de Cuenca, fostering my early exposure to numerical simulations, and encouraging my pursuit of graduate studies in the United States.
I am deeply thankful to Professor Barbara Simpson for graciously welcoming me into her research group and generously funding my graduate studies and research endeavors. Her successful grant applications from esteemed bodies such as the National Science Foundation (NSF) and the American Institute of Steel Construction (AISC) have enabled me to engage in meaningful and impactful research within my specialized domain, under her expert tutelage.
