报告人简介:
Klas Udekwu博士,就读于瑞典的乌普萨拉(Uppsala)大学,先后获得硕士、博士学位。现任美国University of Idaho生物科学系助理教授,瑞典农业科学大学水生科学与评估系高级研究员。曾任瑞典斯德哥尔摩大学分子生物科学系温纳格伦研究所副高级讲师,瑞典卡罗林斯卡学院瑞典医学纳米科学中心神经科学系课题组组长/助理教授,是MetaSUB国际联盟的欧洲主要发起人和参与者。研究领域包括微生物种群生物学,基因型和表型抗菌药物耐药性的药效学、生态学和进化,细菌/药物相互作用的数学和实验建模,建筑环境微生物学。他研究运用数学建模指导实验研究,探索微生物如何响应环境变化,包括单个物种和群落层面。主要关注抗生素、进化以及宿主和微生物生理之间的相互作用。目前,他实验室致力于将生态群落理论应用于多微生物群落的计算机模拟和实验研究。
报告内容简介:
Experimental data coupled to mathematical theory has the potential to transform both the fields of clinical microbiology and nutrition as the inherent link between our microbiomes and what we eat becomes more granular and predictable. However, predictable manipulation of community composition to alter ecosystem function, including disease amelioration remains elusive. We combine the engineering-derived theory of control with experimentally obtained data as an iterative tool to incorporate in our efforts to target specific groups of microbes for either negative or positive selection. I will present two recent studies from our laboratory based on an underlying ecological guild mindset; i) a clinical application of control theory to limit collateral antibiotic resistance arisal in exposed populations, and, ii) control-derived nutrient switching regimen to positively select for particular species in a simple, model, anaerobic community.
