Sadie VanHorn has joined the lab as a graduate student (Developmental, Regenerative & Stem Cell Biology Program). Sadie received her degree in Molecular Biology from Ohio Northern University in 2018. In Dr. Jamie Sider’s laboratory at Ohio Northern, Sadie studied the role of CASK protein in polar cell migration during Drosophila melanogaster oogenesis. Her first experience at WashU was in the lab of Dr. Elizabeth Haswell, studying MSL expression and localization in Arabidopsis thaliana while participating in the AMGEN Scholars Program. Currently, she is in the Developmental, Regenerative and Stem Cell Biology program. In the Morris lab, Sadie will be developing methods to track cellular history in reprogramming models and intestinal organoids to probe the relationships between stem cell, progenitor, and terminally differentiated cell populations. Welcome, Sadie!
