2014年中國科學(xué)院“引進(jìn)杰出技術(shù)人才”，任研究院支撐部門“原子頻標(biāo)與激光技術(shù)中心”執(zhí)行副主任。主要從事超穩(wěn)定激光、光鐘比對與遠(yuǎn)程傳遞等方面的研究工作。為研究院提供超穩(wěn)定激光、激光鎖頻、鎖相等技術(shù)支撐。有豐富的激光鎖頻及超穩(wěn)定腔設(shè)計(jì)經(jīng)驗(yàn)。成功將Nd:YAG固體激光器相對頻率不穩(wěn)定度降低到10-17的水平，研制出頻率不穩(wěn)定度0.1 Hz的Nd:YAG超穩(wěn)定激光。研制出適用于太空的可搬運(yùn)超穩(wěn)定光學(xué)參考腔。發(fā)表的與超穩(wěn)定激光相關(guān)的SCI文章11篇。
