简介:
Ravi Palanivelu,遗传学博士。1998年取得美国乔治亚大学获博士学位,1999年-2004年在任芝加哥大学做博士后研究,2004年-2005年成为芝加哥大学助理教授,2006年至今为亚利桑那大学副教授。主要从事:细胞和发育生物学、遗传学和表观遗传学等。其在遗传学领域已经有几十年的积累,特别在植物生殖发育领域有系统的研究有深厚的基础。重点研究目标是识别和描述花粉管信号生成及其导向作用,最终到达雌蕊进入胚囊完成双受精作用。目前主要致力于解决植物生殖生物学中一个长期但却鲜为人知的基本问题:雌性配子体如何控制双受精作用?已在Plant Cell、Plant Journal、Current Biol.、PLoS Genet等杂志发表文章几十篇。
