R. Dean Astumian

R. Dean Astumian is a Professor of Physics in the Department of Physics and Astronomy at the University of Maine, based in Bennett Hall (Room 122) with contact details astumian@maine.edu and 207/581-1024.

His academic credentials include:

• B.S. in Chemistry (1978), University of Texas at Arlington
• M.S. in Chemistry (1982), University of Texas at Arlington
• Ph.D. in Mathematical Science/Physical Chemistry (1983), University of Texas at Arlington

Professor Astumian's research centers on biophysics and condensed matter physics, specializing in chemically driven molecular motors and pumps. His work investigates energy transduction mechanisms at the molecular scale, focusing on non-equilibrium thermodynamics, kinetic asymmetry, and directional motion in synthetic and biological systems. This research bridges fundamental physics with applications in nanotechnology and synthetic biology.

His 2023-2025 publications reveal persistent exploration of molecular ratchets, enzyme chemotaxis, and artificial molecular machines. Key themes include dissipation-driven directionality, electric molecular motors, and compartmentalized reaction networks, demonstrating consistent innovation in understanding how chemical energy drives mechanical motion at nanoscales across diverse chemical and biological contexts.
