About

Dmitry Matyushov is a professor of physics and chemistry at Arizona State University with research interests in theoretical and computational condensed matter physics, physical chemistry, and biophysics. His academic background includes an undergraduate degree from the Moscow Institute of Physics and Technology in 1986, a doctorate in theoretical physics from Kiev State University and the Ukrainian Academy of Sciences in 1989, and postdoctoral work in Vienna and at the University of Utah. His research encompasses spectroscopy, solvation, phase and glass transitions, complex fluids, electron transfer, dielectric spectroscopy, and bioenergetics, with current focus on protein dynamics, electrostatics of the protein-water interface, and problems related to ergodicity breaking and non-equilibrium ensembles in biology and enzyme catalysis.

Selected publications

• Reorganization energy of electron transfer

  Physical Chemistry Chemical Physics · 2023 · 64 citations

  1st authorCorresponding

  The theory of electron transfer reactions establishes the conceptual foundation for redox solution chemistry, electrochemistry, and bioenergetics. Electron and proton transfer across the cellular membrane provide all energy of life gained through natural photosynthesis and mitochondrial respiration. Rates of biological charge transfer set kinetic bottlenecks for biological energy storage. The main system-specific parameter determining the activation barrier for a single electron-transfer hop is…

• Dielectric Susceptibility of Water in the Interface

  The Journal of Physical Chemistry B · 2021 · 35 citations

  1st authorCorresponding

  It has long been anticipated that dielectric constants of polar liquids are reduced in the interfacial layer. Recent experiments and computer simulations support these expectations. A strong reduction of the dielectric constant is found in the direction perpendicular to a planar substrate, while the parallel response is bulk-like. This Perspective highlights recent theoretical calculations and simulations with an eye on relating them to properties observable in the laboratory. The average interf…

• Electron Tunneling in Biology: When Does it Matter?

  ACS Omega · 2023-07-20 · 25 citations

  articleOpen accessSenior authorCorresponding

  *. Protein flexibility and dynamics affect the magnitude of the maximum hopping rate within the crossover distance. Changes in protein flexibility between forward and backward transitions contribute to vectorial charge transport. For biological energy chains, charge transport through proteins is not defined by universal parameters, and protein identity matters.

• Dielectric friction, violation of the Stokes-Einstein-Debye relation, and non-Gaussian transport dynamics of dipolar solutes in water

  Physical Review Research · 2021 · 23 citations

  Senior authorCorresponding

  The authors explore the coupling between rotations and translations through electrostatic interactions with the medium and show that it leads to non-Gaussian translational dynamics and violation of Stokes-Einstein-Debye relation.

• Long-Range Conductivity in Proteins Mediated by Aromatic Residues

  ACS Physical Chemistry Au · 2023-06-02 · 22 citations

  articleOpen accessSenior authorCorresponding

  Single-molecule measurements show that many proteins, lacking any redox cofactors, nonetheless exhibit electrical conductance on the order of a nanosiemen over 10 nm distances, implying that electrons can transit an entire protein in less than a nanosecond when subject to a potential difference of less than 1 V. This is puzzling because, for fast transport (i.e., a free energy barrier of zero), the hopping rate is determined by the reorganization energy of approximately 0.8 eV, and this sets the…
