Biography
Yichen Li is interested in interrogating the epigenetic regulation in cancer progression. He study structure and functions of nuclear pore complex with single-molecule and super-resolution imaging technique during his Ph.D. work in the lab of Weidong Yang at Temple University. During his Ph.D. program, he studied the spartial organization of phenylalanine-glycine (FG) motif containing nucleoporins and nucleocytoplasmic transport of biomolecules such as transcription factors and mRNA. In Andrew Xiao's lab, he works on study N6-methyladenine based epigenetic regulation of genome adapation in cancer with multiple fluorescence imaging techniques.
