James Sethna

James Sethna is the James Gilbert White Professor of Physical Sciences Emeritus in the Department of Physics at Cornell University. His research interests include theoretical condensed-matter physics, biological physics, and materials science, with a focus on disordered systems, glasses, and nonlinear renormalization-group methods. He has contributed to the study of sloppiness in models across various fields and has developed new approaches to understanding rigidity transitions. Sethna has held academic positions at Cornell University since 1984 and has been recognized for his scholarly work through various publications and collaborations.

James Sethna is a Professor of Physics at Cornell University, specializing in statistical mechanics, materials physics, biophysics, and dynamical systems. His research explores the behavior of complex systems, including single-atom transistors, biological models, and critical phenomena in materials. He investigates how entropy, order parameters, and nonlinear dynamics shape physical and biological systems. His work also addresses the challenges of parameter sensitivity and model predictability in systems with many poorly known parameters. Sethna's research spans from condensed matter physics to soft matter and biological systems, emphasizing the interplay between disorder, complexity, and emergent behavior.
