AREAS OF EXPERTISE:

Marcus Beck is a scientist studying the use of water quality and biological monitoring data to support environmental assessment programs. He has worked to develop biological assessment tools for glacial lakes, including a multimetric approach to characterize stressors of aquatic macrophytes. His previous work as a post-doctorate researcher with the USEPA Gulf Ecology Division focused on statistical and simulation modelling of time series data to improve understanding of nutrient pollution dynamics in coastal systems. He is an advocate for the use of open science workflows to improve transparency and reproducibility of research products.
