What if the secret to understanding life lies in the mathematics of systems that can never sit still? In this episode of No Reason to Get Excited (NRTGE), Dr. Aaron Winkler sits down with Grant Rotskoff, Assistant Professor of Chemistry at Stanford University, to explore the breathtaking frontier where statistical physics, computation, and biology collide.
From the unsolved mystery of how ATP, the "spark of life," actually hydrolyzes, to the way muscle tissue self-assembles from molecular ratchets, Grant unpacks what it means to study living systems that are, by their very nature, perpetually far from equilibrium. Along the way, Aaron draws striking parallels between the molecular machinery of cells and the deepest questions of consciousness, attention, and emergence.
About the Guest
Grant Rotskoff is an Assistant Professor of Chemistry at Stanford University. His research sits at the intersection of theoretical chemistry, statistical physics, and machine learning, with a focus on understanding the non-equilibrium dynamics of biological systems. He trained as a mathematician at the University of Chicago before turning to biophysics, and his lab uses cutting-edge computational methods, including machine-learned interatomic potentials and importance sampling, to study problems ranging from ATP hydrolysis to the self-assembly of muscle tissue.
