Diana Baetscher

Molecular ecology, population genetics, and fishes


I’m a postdoc with Nina Overgaard Therkildsen and Pete McIntyre in the Department of Natural Resources at Cornell University.

I’m heading up a project to use metabarcoding to determine what exactly goes into fish food and which of the oceans’ wild fish stocks are impacted.

I finished my PhD in Ocean Sciences at the University of California, Santa Cruz in March 2019.


Feel free to contact me with questions or if you need access to publication PDFs.
