A long-term perspective is useful to distinguish natural ecosystem variability from human impacts, and to recognize the rates and magnitude of environmental change. Paleolimnology is the science that uses the physical, chemical, and biological information preserved in sediment records to track environmental changes over long periods of time, often decades to millennia. My research program combines a paleolimnological approach and modern ecological sampling to better understand how freshwater ecosystems respond to natural processes and human-caused stressors. This interdisciplinary approach can be a powerful tool to determine cause-and-effect, establish baseline ecosystem conditions, and set realistic recovery goals following the impacts from human activities. My proposed research program aims to understand the causes and effects of nuisance growths (blooms) of the bottom-dwelling alga,

长期的观点有助于区分自然生态系统的变异性和人类的影响，并认识到环境变化的速度和幅度。古湖泊学是一门利用保存在沉积物记录中的物理、化学和生物信息来追踪长期（通常是几十年到几千年）环境变化的科学。我的研究项目结合了古湖泊学方法和现代生态采样，以更好地了解淡水生态系统如何应对自然过程和人为造成的压力。这种跨学科的方法可以作为一种强大的工具来确定因果关系，建立基线生态系统条件，并在人类活动的影响下设定现实的恢复目标。我提出的研究计划旨在了解海底藻类滋扰生长（繁殖）的原因和影响，
