Foundational Discoveries in Actin Regulation: An Interview With <scp>T</scp> om <scp>P</scp> ollard

Dr. Thomas D. Pollard's work transformed cytoskeleton research into a quantitative, mechanistic science. Over five decades, he established core principles of actin dynamics, including filament polarity, assembly kinetics, unconventional myosins, and the molecular basis of branched networks and contractile ring formation. By integrating biochemistry, structural biology, genetics, microscopy, and modeling, his studies defined the logic of cellular architecture and motility. In this interview, Dr. Pollard reflects on key discoveries that shaped the actin field and on the role of quantitative thinking in biology. Perspectives from former trainees highlight his lasting influence as a mentor and the interdisciplinary culture that shaped generations of scientists.
