Prof. Xunwei Wu (MD PhD)

Professor, Principal Investigator, School of Stomatology, Shandog University, Jinan, China




Xunwei Wu received his MD from Zhejiang Medical University, Hangzhou in 1993, and his PhD from Fudan University, Shanghai, in 2001. He did his post-doctoral training in Max Planck Institute of Biochemistry, Germany and then in Harvard Medical School, Boston. In 2010, he became a senior scientist in Adreans Research Institute, Atlanta, and in 2013 he moved back to Harvard Medical School as an instructor position. In 2015, he accepted a principal investigator position in Shandong University, Jinan, China.


Dr. Wu’s research interest is to understand the function of dermal fibroblasts in maintaining skin homeostasis. His current research is mainly focused on two areas:

(1) The role of dermal fibroblast in regulating the development of melanoma;

(2) The role dermal fibroblast in controlling wound healing and skin regeneration.
