主讲人简介:

龚骏,中山大学“百人计划”教授,博士生导师。主要从事海洋微生物生态与物质循环、微型生物多样性研究。近年来,着重利用一系列现代分子生态学技术( 高通量测序、荧光原位杂交、群落指纹图谱、定量PCR、基因文库与系统进化分析、组学分析等)、流式细胞检测、单细胞分析及生物地化过程的稳定同位素示踪技术等,研究人类活动及全球变化背景下河口、盐沼、近海环境中原核与真核微生物(原生生物、单细胞真菌)多样性与群落结构、物质循环功能类群的变化规律;试图揭示近海微生物与其驱动的碳、氮、硫元素生物地球化学过程间的耦合机制及与生态系统功能变化之间的关系、海洋微食物环中原生生物与细菌之间的相互作用(捕食与共生)等。迄今在Environ. Microbiol., Appl. Environ. Microbiol., Protist, Front. Microbiol., Syst. Appl. Microbiol., J. Eukaryot. Microbiol., Estuar. Coast. Shelf Sci. 等国内外学术刊物上发表论文100余篇,其中SCI收录80余篇;参加专著2部,译著1部。
