Brief bio: There is no argument for the fact that plants feed the world. The concern is how to help plants fulfill this task efficiently and economically. After college, I pursued my study in plant molecular biology under the supervision of Prof. Jisen Shi at the Key Laboratory of Forest Genetics and Biotechnology, Nanjing Forestry University (NFU). During that period, I tried to unravel the roles of some regulators, like expansins and GPI-anchored proteins, in determining the secondary cell wall formation. After having earned my Ph.D. in genetics, I joined the lab of Prof. Rentao Song at Shanghai University (SHU) as an assistant and later associate professor, where I began to focus on maize kernel development and functionally characterized several mutants related to either storage compounds deposition or endosperm and embryo development, like opaque1, proline responding1/opaque6, dek36 and dek40. Afterwards, I joined the lab of Prof. Claudia Köhler at The Swedish University of Agricultural Sciences (SLU) as a postdoctoral researcher to study epigenetic mechanisms governing Arabidopsis endosperm development, especially roles of paternally expressed imprinted genes (PEGs) in postzygotic barriers towards interspecies and interploidy hybridizations. In November 2017, I moved to Henan Agricultural University to run my own lab. Currently, the topics we address are: ⑴Mechanisms underlying the deposition of storage compounds in cereal; ⑵Genetic and epigenetic control of plant seed development, using maize and Arabidopsis. Our final goal is to translate our research into improving cereal grain quality and yield by molecular breeding strategies.

简介：毋庸置疑植物养活了全世界，如何才能使植物更高效经济地完成使命是一个重要的科学问题。本科毕业后，我继续在母校南京林业大学林木遗传育种教育部重点实验室施季森教授课题组攻读遗传学博士学位，探究了扩展蛋白（expansin）和糖基磷脂酰肌醇锚定蛋白（GPI-anchored protein）在植物次生壁形成中的作用。博士毕业后，我应聘加入上海大学生命科学学院宋任涛教授团队，历任助理教授和副教授，开始关注玉米籽粒发育，先后解析了多个与籽粒储藏物质积累、胚和胚乳发育紧密相关的突变体，包括opaque1、proline responding1/opaque6、dek36 and dek40。随后，有幸加入瑞典农业大学Claudia Köhler教授实验室进行博士后研究，聚焦于拟南芥胚乳发育的表观遗传调控，特别是父本表达印记基因在种间和不同倍性杂交造成合子胚生殖障碍的分子机制。2017年11月，我应聘到河南农业大学农学院建立自己的实验室。目前，我们实验室以单子叶玉米和双子叶拟南芥为材料进行如下两方面的研究：⑴作物种子储藏物质积累的分子机制；⑵植物种子发育的遗传与表观遗传调控。我们最终的目标是将所获得的研究结果应用于分子育种，从而提高作物的品质和产量。
