Research Interests

Andy’s primary research focus is in stream ecology where his background in hydrology provides additional skills to examine the dynamic interactions of the physical, chemical and biological processes that control stream communities. His master’s work, predicting flow statistics in the ungaged watersheds of the Lake Tahoe Basin for fisheries habitat assessment, integrated watershed scale parameters with habitat requirements for salmonid species in a modeling effort to help prioritize fisheries restoration. His PhD research, Stalked Diatom Blooms: environmental controls and ecological consequences, seeks to identify the environmental and trophic controls of stalked diatom blooms and to identify potential food web consequences.
