I analyzed the bones found in the ears of fish (otoliths) by looking at the stable isotopes found within them, which is a seldom-studied aspect of otoliths. Most of my daily work involved working on bone samples in the lab and taking them through a multi-step process, from initially dissecting them from frozen fish heads to running the samples on a mass spectrometer. We hope that a greater understanding of otolith geochemistry will help us understand the human impact on ecosystems and develop new metrics to measure this. This project highly influenced my choice of senior thesis and supports future publications in the Ward lab.
