About

Sam Rivera is a pioneering biomechanist whose research explores the extraordinary ways animals manipulate their environment, with a particular focus on the mechanics of feeding and movement. Rivera’s most celebrated work, "Suction feeding by elephants" (2021, 35 citations), fundamentally reshaped our understanding of elephant behavior. By filming elephants at Zoo Atlanta, Rivera demonstrated that these massive animals—despite possessing a trunk weighing over 100 kg—can use suction to delicately grasp lightweight vegetation. This experimental and theoretical investigation revealed a previously unknown feeding strategy, challenging long-held assumptions about the limits of muscular control and fluid dynamics in large mammals. Rivera’s contributions bridge engineering and biology, offering insights into how animals solve complex physical problems. With a growing citation record and a reputation for innovative, hands-on research, Rivera is a rising voice in comparative biomechanics, inspiring students to look beyond the obvious and uncover the hidden physics of everyday animal life.
