Biography

Dr. Angie Boysen’s research focuses on understanding the roles that microorganisms play in controlling the ocean biogeochemical cycles. She is broadly interested in how microorganisms adapt to and shape their dynamic environments by producing and using different small molecules (metabolites) and proteins. Dr. Boysen looks forward to continuing her research with PLU undergraduates. Stay tuned for opportunities to join the lab. Read more about Dr. Boysen’s research on her research webpage.
