This grant supports an interdisciplinary research project in applied mathematics and aquatic ecology. Specifically, the principal investigator will spend an academic year visiting the Department of Biology atthe University of Texas-Arlington to substantially broaden his background in aquatic ecology and expand his skills and knowledge in mathematical modeling of population dynamics, microbial competition, and transportprocesses in heterogeneous media. The main research effort in this project is to compare experimental gradostat results to those predicted by existing theoretical models of resource competition, and to develop and implement new, important mathematical and computational methods for accurate modeling of the bacteria-algae-nutrients interactions in a general gradostat.The goals of the principal investigator in the proposed research projectare:(1) to participate in and assist with the modeling of ongoing experiments on microbial competition along spatial gradients of resource supply;(2) to develop a better understanding of aquatic microbial ecology and the skills necessary for continued research in this area; and (3) to create curriculum guides and supplemental materials for new graduate and undergraduate courses in the principal investigator's home department as well as in the Department of Biology at the University ofTexas-Arlington.This interdisciplinary project will be the foundation for a continuing collaboration between the two departments aimed at developing a combined experimental and theoretical research program addressing microbial interactions in heterogeneous systems for application to problems in aquatic ecology and environmental engineering. This IGMS project is jointly supported by the MPS Office of Multidisciplinary Activities (OMA) and the Division of Mathematical Sciences (DMS).

该补助金支持应用数学和水生生态学的跨学科研究项目。具体来说，首席研究员将花一个学年访问生物系atthe德克萨斯大学阿灵顿大大拓宽了他的水生生态学的背景，并扩大他的技能和知识的数学建模的人口动态，微生物竞争，和transportprocesses在异质介质。该项目的主要研究工作是将实验梯度仪结果与现有的资源竞争理论模型预测的结果进行比较，并开发和实施新的重要数学和计算方法，用于精确模拟一般梯度仪中的细菌-藻类-营养物相互作用。（1）参与并协助正在进行的关于微生物沿着资源供应空间梯度竞争的实验建模;（2）培养对水生微生物生态学的更好理解和在这一领域继续研究所需的技能;以及（3）为主要研究者的家庭部门以及德克萨斯大学生物系的新研究生和本科生课程创建课程指南和补充材料-阿灵顿。这个跨学科项目将成为两个部门之间持续合作的基础，旨在开发一个综合实验和理论研究计划，解决异质系统中微生物相互作用，以应用于水生生态学和环境工程中的问题。 该IGMS项目由MPS多学科活动办公室（OMA）和数学科学部（DMS）共同支持。
