Microbiologist Erin Stelzer samples a wetland for infectious avian influenza virus at DeSoto National Wildlife Refuge, Iowa.
Erin A Stelzer
Erin received her Bachelor of Science degree in Microbiology from The Ohio State University. She started her career at the USGS in 2006 at the Ohio Water Science Center. Currently, Erin is working on a variety of molecular microbiological topics including: cyanobacterial toxin genes, taste and odor genes, enteric viruses, and eDNA.

Cyanotoxin mixture models: Relating environmental variables and toxin co-occurrence to human exposure risk
Toxic cyanobacterial blooms, often containing multiple toxins, are a serious public health issue. However, there are no known models that predict a cyanotoxin mixture (anatoxin-a, microcystin, saxitoxin). This paper presents two cyanotoxin mixture models (MIX) and compares them to two microcystin (MC) models from data collected in 2016–2017 from three recurring cyanobacterial bloom locations in Ka

Phytoplankton community and algal toxicity at a recurring bloom in Sullivan Bay, Kabetogama Lake, Minnesota, USA
Kabetogama Lake in Voyageurs National Park, Minnesota, USA suffers from recurring late summer algal blooms that often contain toxin-producing cyanobacteria. Previous research identified the toxin microcystin in blooms, but we wanted to better understand how the algal and cyanobacterial community changed throughout an open water season and how changes in community structure were related to toxin pr
