Sarah J.R. Hansen

Sen. Sarah Hansen is a Senior Lecturer in the Department of Chemistry. Since joining Columbia in 2004 she has taught introductory chemistry lecture/laboratory courses and supports pedagogical development through graduate seminars and workshops. Her aim is to foster a collaborative approach to learning, shifting the teacher into the role of facilitating meaningful engagement between students while decreasing the distance between chemistry in and out of the classroom. Dr Hansen was the 2024 recipient of the Division of Natural Sciences Award for Teaching Excellence.

Her research focuses on reflection, visual engagement, and laboratory learning. She co-edited Eye-tracking for the Chemistry Education Researcher (2019) and serves on the advisory committee for Columbia’s Science of Learning Research Initiative.

From 2020-2023 she served on the Lecturer Advisory Council from 2020-2023, chairing for two years. Through advocacy and committee work she actively seeks opportunities to ensure the unique and vital perspectives of untenured faculty at the University are included in Governance and Policy decisions.
