Wei Song

I received my PhD training in Molecular Medicine with Dr. Alan Tomkinson at the University of Maryland, where I conducted research on the role of human DNA replication and repair proteins in regulating genomic stability. Subsequently, I joined Dr. Tom Petes’s laboratory at Duke University for my postdoctoral research training in Molecular Genetics. At Duke, I have been further pursuing my interests in exploring mechanisms of genomic instability and carcinogenesis. My research projects here focus on identifying chromosomal fragile sites and their relationship with the deficiency of the DNA replication enzyme, DNA polymerase alpha.

Prior to coming to the U.S., I received training in Clinical Medicine (Nephrology) in China. Through eight years of intense medical training, I developed a strong interest in understanding the fundamental mechanisms of diseases. This interest was the primary reason I pursued research training in Molecular Medicine in the U.S. I enjoy devoting my efforts each day to understanding more about diseases in both clinical and scientific contexts.

I am currently supported by the Molecular Mycology and Pathogenesis Training Program (T32-AI52080) from the NIH.
