I earned my Bachelor's degree in Artificial Intelligence from Imam Abdulrahman bin Faisal University, where I focused on applying machine learning to medical data. I then joined KAUST as an MS/PhD student, where I have published research in Natural Language Processing (NLP). Currently, my work centers on Multi-Modal Large Language Models, exploring the intersection of NLP and computer vision to advance AI systems that can understand both language and visual information.

My research focuses on Multi-Modal Large Language Models, Vision-Language Models, natural language processing, and computer vision. I am particularly interested in identifying and addressing the limitations of current AI models, exploring where they fail and developing methods to overcome these gaps. My work aims to improve model robustness, reliability, and performance, advancing the capabilities of AI systems to better understand and process both textual and visual information.
