My name is Xiaoyu Sun. I am a Ph.D. candidate in Oral Medicine at the Academic Centre for Dentistry Amsterdam (ACTA), University of Amsterdam, the Netherlands. Currently, I hold the positions of Associate Professor at the School of Stomatology, Wenzhou Medical University, and Associate Chief Physician at the Affiliated Stomatology Hospital of Wenzhou Medical University. My primary research focus is on the mitochondrial molecular mechanisms underlying diabetes-associated periodontitis. This research has systematically elucidated the crucial role of oxidative stress in the pathogenesis of periodontitis. I have further demonstrated that mitochondrial dysfunction plays a key role in the pathological alterations of diabetes-associated periodontitis. These findings were published as a cover article(J Clin Periodontol. 2017, 44:463-471).I have authored over 20 SCI-indexed research papers related to periodontitis in authoritative journals in the field of dentistry, including the Journal of Clinical Periodontology. Among these, 5 papers list me as the first or co-first author. Concurrently, I serve as the principal investigator for one National Natural Science Foundation of China (NSFC) Youth Project, and have successfully led and concluded one municipal/regional level research project. I have participated in multiple NSFC General Program projects, co-authored one monograph, and hold two invention patents. As an active member of the academic community, I have completed 28 peer reviews for manuscripts submitted to 4 different SCI journals, contributing to the ongoing academic discourse in the field of periodontology. My long-term research goal is to establish an interdisciplinary research paradigm for diabetes and periodontitis. I aim to make key breakthroughs in two major scientific questions: mitochondrial homeostasis regulation under metabolic dysregulation and the host-microbe interaction mechanisms. The ultimate objective is to develop precision diagnostic and therapeutic strategies for periodontitis patients with systemic diseases. In professional practice, I place particular emphasis on integrating clinical thinking with research capabilities and am adept at solving complex cases through multidisciplinary collaboration. My active listening skills and patient communication techniques enable me to accurately identify clinical needs. Furthermore, my experience in successfully mentoring 12 graduate students through their research projects has honed my ability to provide tailored guidance and fostered my team leadership. My personal interests are reading, traveling and watching movies.
