个人简介

2005年11月至2010年7月在捷克国家科学院寄生虫学研究所攻读博士学位，研究布氏锥虫线粒体生物学。毕业后获得欧盟玛丽居里博士后学者计划的资助，在英国纽卡斯尔大学医学院从事微孢子虫、贾第虫等寄生原虫中高度退化线粒体的蛋白质组学、细胞和进化生物学。

2013年6月开始在美国圣路易斯华盛顿大学医学院分子微生物学系David Sibley实验室从事弓形虫的寄生生物学和病原生物学研究。主要研究方向为弓形虫的钙信号及其抑制药物的筛选、遗传操作工具的改造和顶体复合体（apical complex）的分子构成和功能。近2-3年来，对顶体复合体的研究获得了突破性的进展，发现了一系列的新蛋白质，深入探讨了这些蛋白质的功能作用（Long S, et al. Nature Communications, 发表日期：2017年12月21日），并深入研究了定位于该细胞结构的钙调蛋白的功能（Long S et al, PLoS Pathogens, 2017）。改造和开发的新遗传操作技术整合在上述两项研究工作中，发表后得到F1000专家的推荐和点评，并受邀为Bio-Protocol写作章节。
