　　1998年畢業(yè)于中國(guó)醫(yī)科大學(xué)七年制外文系，獲得醫(yī)學(xué)學(xué)士學(xué)位;2003年3月畢業(yè)于日本神戶大學(xué)，獲得醫(yī)學(xué)博士學(xué)位;2003年6月至2008年7月在美國(guó)哈佛醫(yī)學(xué)院細(xì)胞生物系從事博士后研究;2008年7月起任中國(guó)科學(xué)院上海生命科學(xué)研究院生物化學(xué)與細(xì)胞生物學(xué)研究所研究員，博士生導(dǎo)師和研究組長(zhǎng)。

　　真核細(xì)胞中，核膜將貯存遺傳信息的DNA與翻譯遺傳信息的核糖體分隔在細(xì)胞核與細(xì)胞質(zhì)中。由RNA介導(dǎo)的遺傳信息跨核膜傳遞為所有真核生物生命活動(dòng)所必需。新生pre-mRNA在細(xì)胞核內(nèi)完成一系列復(fù)雜加工后，成熟mRNA被轉(zhuǎn)運(yùn)到細(xì)胞質(zhì)中進(jìn)行翻譯。mRNA出核轉(zhuǎn)運(yùn)與pre-mRNA加工過程相互偶聯(lián)，確保遺傳信息的精準(zhǔn)表達(dá)。細(xì)胞核中普遍存在RNA質(zhì)量監(jiān)控系統(tǒng)，可快速識(shí)別并降解攜帶錯(cuò)誤遺傳信息的或異常mRNA，從而保證遺傳信息的準(zhǔn)確傳遞。新生轉(zhuǎn)錄本被快速、準(zhǔn)確地分選到出核或降解通路是遺傳信息高效、精準(zhǔn)傳遞的基本保證，具有重要生物學(xué)意義。本實(shí)驗(yàn)室自2008年成立以來，主要圍繞“新生轉(zhuǎn)錄本出核和降解的命運(yùn)決定與調(diào)控”這一基因表達(dá)領(lǐng)域的關(guān)鍵科學(xué)問題，系統(tǒng)性地開展mRNA出核與加工的復(fù)雜關(guān)聯(lián)、RNA的質(zhì)量控制和核內(nèi)降解及其調(diào)控兩個(gè)方向的研究工作。具體如下。

　　利用分子與細(xì)胞生物學(xué)、生物化學(xué)、化學(xué)生物學(xué)及多種組學(xué)研究手段及技術(shù)，重點(diǎn)研究：

　　1、mRNA出核與pre-mRNA加工的復(fù)雜關(guān)聯(lián);

　　2、RNA的質(zhì)量控制和核內(nèi)降解及其調(diào)控;

　　3、細(xì)胞核亞結(jié)構(gòu)調(diào)控RNA出核或降解的生理病理機(jī)制。
