Dr. Nasir Ullah currently serves as a researcher at the Australian Institute for Innovative Materials (AIIM), University of Wollongong, Australia. He holds a Doctor of Engineering in Materials Science and Engineering from the University of Science and Technology of China (USTC), where he completed his doctoral studies between 2018 and 2025, and a second PhD in Physics Science from the University of Wollongong. Before pursuing his research career, Dr. Ullah served as a secondary school teacher in Pakistan, reflecting his long-standing commitment to education. His current research interests encompass Cold Spray Coatings, wear and corrosion resistance, and radiation-matter interactions, with a specific focus on biomedical applications—particularly the development of nanomaterials that function as ROS (Reactive Oxygen Species) scavengers. Dr. Ullah’s interdisciplinary background in materials science and physics underscores his dedication to addressing complex engineering and biomedical challenges through innovative surface treatments and nanomaterial design.
My doctoral journey at the University of Science and Technology of China (USTC) began in 2018, marking the start of one of the most transformative periods of my academic and personal life. As an international student pursuing advanced research far from home, I entered USTC with great ambition and curiosity, eager to grow within one of China’s leading scientific institutions.
Like many students around the world, my academic trajectory was unexpectedly disrupted by the COVID-19 pandemic. The unprecedented global crisis brought significant challenges to both research progress and daily life. Laboratories closed temporarily, travel restrictions created uncertainty, and long periods of separation from academic environments tested not only my patience but also my resilience. Yet, rather than discouraging me, these difficulties ultimately became a source of motivation and reflection during the second phase of my doctoral studies.
In 2023, after resuming my research activities, I rejoined my research group at the Institute of Metal Research (IMR) with renewed determination and a clearer sense of purpose. Returning to the laboratory after such a challenging period deepened my appreciation for scientific research and strengthened my commitment to academic excellence. Through perseverance, consistent effort, and the guidance of my supervisors and colleagues, I successfully completed my PhD in November 2025.
Throughout this journey, USTC provided an exceptional academic environment that played a pivotal role in shaping my development as a researcher. The university’s state-of-the-art laboratory facilities, rigorous scientific culture, and intellectually stimulating atmosphere significantly enhanced my technical expertise and critical thinking skills. More importantly, the experience trained me to approach scientific problems with discipline, creativity, and persistence.
Beyond academics, my years in China were also deeply enriching on a personal and cultural level. Living and studying in China allowed me to immerse myself in the country’s rich cultural heritage, diverse traditions, and remarkable culinary culture. During my time there, I had the opportunity to travel across both major metropolitan cities and rural communities, experiences that offered me valuable insights into the social and economic contrasts between urban and rural life. These experiences broadened my worldview and helped me better understand societal dynamics beyond the boundaries of academia.
Looking back, my years at USTC were not only about earning a degree; they were about growth, resilience, and transformation. The challenges I encountered strengthened my character, while the opportunities I received expanded both my academic and personal horizons.
Following my graduation, I joined the University of Wollongong, an opportunity that would not have been possible without the skills, resilience, and academic training I developed during my time at USTC. The university provided me not only with scientific knowledge, but also with the confidence and perseverance necessary to pursue an international academic career.
I remain deeply grateful to USTC for shaping my academic journey, supporting my growth as a researcher, and laying a strong foundation for my future career and aspirations.
