About

David G. Matthews is a biomechanist and evolutionary biologist whose research bridges the gap between fish biology and bio-inspired robotics. His work centers on understanding how fin morphology, stiffness, and hydrodynamic interactions drive swimming performance and adaptive evolution. In his highly cited 2021 study on fin–fin interactions in a simplified biomimetic fish model (31 citations), Matthews revealed how median fins work in tandem to improve propulsion—a finding with direct implications for both evolutionary biology and underwater vehicle design. His 2022 paper on the role of the caudal peduncle (26 citations) demonstrated that altering tail stiffness and angle of attack significantly changes swimming efficiency, highlighting a key anatomical feature fish use for maneuverability. Most recently, Matthews contributed to a 2023 synthesis on genes, morphology, performance, and fitness (17 citations), offering a framework for linking genetic variation to whole-organism function. With over 70 total citations and growing influence, Matthews is shaping how we understand the mechanical principles underlying fish locomotion—and how those principles can inspire more agile, efficient robotic swimmers.
