Undergraduate Research: Bending Mechanics of Sea Urchin Spines
During my junior and senior years as a student at College of the Holy Cross, I studied the bending mechanics of sea urchin spines under Dr. Stephanie Crofts. Here, I collected spines from purple (S. purpuratus), pale (S. pallidus), and green (S. droebachiensis) sea urchins and, using CT scans, measured their second moment of area-- a measure of how mass is distributed around a central axis. Higher second moment of area values indicate a higher flexural stiffness, and a greater resistance to bending.
This first foray into biological research taught me the basics of designing a study, collecting data, and interpreting scientific literature. It also gave me the opportunity to study for a summer at University of Washington's gorgeous Friday Harbor Labs, and to travel to Phoenix, AZ to present a poster at the Society of Integrative and Comparative Biology's 2022 conference.
