My name is Abdulwasea Alkhazzan, and I am from Yemen. I recently earned my PhD in Mathematics from Northwestern Polytechnical University (NPU), where I was honored as an Outstanding Graduate. Before joining NPU, I completed my Master’s degree at Hohai University, China, in 2019 and my Bachelor’s degree at Sana'a University, Yemen.
Choosing China for Higher Education
After completing my bachelor's degree, I began working as a lecturer at Sana'a University. During that time, I thought long and hard about the best place to continue my studies. China's remarkable progress in education and research, coupled with the strong global reputation of its universities, made it the ideal choice for me. In 2016, I applied for a CSC scholarship to study for a master's degree in China, and I was fortunate enough to be selected.
When I first arrived in China, I felt excited and a little nervous about adapting to a new country and academic system. However, thanks to the friendly environment at Hohai University, I quickly settled in. I became part of a supportive academic community, where I learned from great professors, worked with talented colleagues, and participated in important research. During my master's study, I published nine research papers, which helped me grow as a researcher and gain valuable experience.
In 2020, my journey to NPU began when I received a scholarship to pursue a PhD, marking an important step in my academic and research career in China. However, this was also a challenging time, as the world was struggling to fight the COVID-19 pandemic, making the transition even more difficult.
My Research: Stochastic Epidemic Models
During my PhD, I focused on stochastic epidemic models, a field that helps us understand how infectious diseases spread. Given the global impact of viral diseases, my research aimed to provide new insights into how these diseases evolve under different conditions. Using rigorous mathematical modeling and stochastic analysis, I identified the conditions that lead to disease extinction as well as those that allow the disease to persist. Additionally, I explored how various factors, including media coverage, city-to-city transportation, different types of noise, and vaccination strategies, affect disease dynamics.
Conducting research at NPU was both challenging and rewarding. The university provided advanced research facilities and access to a wide range of academic resources. I spent long hours in the research lab and library, refining my models and running simulations, which greatly enhanced my analytical skills and deepened my understanding of complex disease behavior.
Scientific Contributions and Achievements
Despite the challenges I encountered during my PhD program, particularly the lockdowns and restrictions imposed by the COVID-19 pandemic, I successfully published 17 SCI papers, with 9 of them as the first author in reputable journals. These publications showcase the dedication and perseverance I invested in my research, even amid difficult circumstances. Along this journey, I was also honored to receive several prestigious awards, including:
1. First Class of Wu Yajun Special Award, 2023, NPU, China
2. Academy Star Trophy, 2023 & 2024, NPU, China
3. Best Paper Award, 2024, 1st Belt and Road Academic Forum, NPU, China
4. Best Poster Award, 2024, 2nd Belt and Road Academic Forum, NPU, China
5. Third Prize Award, 2023, 3rd Postgraduate Academic Forum, NPU, China
Each of these achievements reflects not only my hard work but also the strong academic foundation provided by NPU and the endless support of my supervisor, Professor Yufeng Nie, and my advisor, Professor Jungang Wang.
Study Experience at NPU
Studying at NPU has been one of the most important experiences in my life. From the very start, I received constant encouragement and great guidance from my supervisor and my advisor. Their knowledge and advice were key in helping me throughout my studies. Their support went beyond academics. They created a friendly and encouraging environment that helped me face the challenges of research with confidence. Their mentorship didn’t just help me finish my PhD, but also changed how I think about scientific research, from developing ideas to testing and proving them. With their guidance, I developed not only technical skills but also a deeper understanding of research and its real-world applications.
Beyond academics, NPU provided an environment that supported both personal and professional growth. The university has a diverse community of international students, and through my interactions with them, I was able to share knowledge, ideas, and learn about different cultures. Participating in academic forums, workshops, and international conferences helped me gain new perspectives and build valuable connections in the research field.
Although there were challenges, especially with balancing research, publications, and academic duties, the support from my professors and the International Office helped me get through them. The well-organized academic programs by the international office were also important in helping me stay focused on producing high-quality work.
Encouragement for Future Students
Studying in China has been an incredibly rewarding experience, and I highly recommend that international students consider continuing their studies here, especially at NPU. The university provides excellent research opportunities, a supportive academic community, and an environment that encourages creativity. My time at NPU has helped me become a stronger researcher, and I believe future students will find the same inspiration and opportunities here.
Future Plans
Looking ahead, I plan to continue my research in China and contribute to the development of mathematical models in epidemiology. My goal is to work with top researchers and institutions to create models that can help policymakers and healthcare professionals make better decisions on disease prevention and control.
As I advance in my academic career, I remain truly grateful to NPU, my supervisor, my advisor, and the International Office for guiding me throughout my journey. I am excited to keep contributing to the field and to support future students in achieving their academic goals.
