個人簡介
2002年本科畢業於南開大學生命科學學院生物化學系;2009年在中科院上海生命科學研究院生物化學與細胞生物學研究所獲博士學位;2009年至2014年在美國國立衛生研究院(NIH)進行博士後研究工作。2014年11月加入上海科技大學生命科學與技術學院任助理教授(終身教授序列)。
研究工作
物種繁衍依賴於基因組的穩定性,這在細胞內是由一系列精巧而複雜的DNA修復機制負責維持的。然而在某些生理、病理狀態下細胞會激活錯誤傾向性DNA修復機制。因此DNA修復的精確性和錯誤傾向性之間的平衡對於包括癌症在內的疾病發生、衰老和進化都有著重要的意義。我們實驗室將探索由DNA修復引發的突變在疾病發生、衰老以及基因組主動性去甲基化等過程中所起的作用, 主要集中於三個方面: 1)DNA修復在內源基因組水平引發突變的分子機制;2)鑑定並分析參與DNA修復引發突變的新分子和新通路;3)DNA修復引發突變在癌症發生過程中的作用。我們的研究將有助於發現癌症治療的新靶標,完善衰老的DNA損傷學說以及揭示物種進化的分子動力。
