Begin PhD at MBZUAI

Starting PhD at MBZUAI under the guidance of Professor Timothy Baldwin and Dr. Yova Kementchedjhieva, focusing on uncertainty in multimodal learning and vision-language models (VLMs).

About Me

As a Computer Science graduate from Ho Chi Minh City University of Technology – Vietnam National University (HCMUT-VNU), I completed my degree in an accelerated 3.5 years and will soon join the prestigious Mohamed bin Zayed University of Artificial Intelligence (MBZUAI) as a PhD student in Natural Language Processing (NLP).

Throughout my undergraduate journey under the guidance of Assoc. Prof. Dr. Tho T. Quan, I developed strong programming proficiency in Python, Java, and C++, alongside a solid foundation in Machine Learning, Deep Learning, and Multimodal Analysis. My academic coursework and independent research cultivated my passion for state-of-the-art AI methods, particularly in NLP and Multimodal Large Language Models (MLLMs).
