Niels Grønbech-Jensen studies the dynamics and statistics of nonlinear physical systems through analytical and numerical techniques. Much of the work is connected to collaborations with a variety of applied physics objectives. He is also a Professor in the Department of Mechanical and Aerospace Engineering at UC Davis as well as a Faculty Scientist at Lawrence Berkeley National Laboratory in the Applied Mathematics & Scientific Computing Department.

Examples of research interests include classical Molecular Dynamics in the context of atomic and molecular descriptions of soft matter (e.g., bio-membranes and molecular self-assembly) as well as hard matter (e.g., radiation damage in crystals). He is also engaged in the development and analysis of new numerical algorithms for efficient and accurate discrete-time modeling of equations of motion with thermal noise. Another interest is a thorough investigation of the driven-damped pendulum equation with a present emphasis on the dynamics of superconducting (Josephson) tunnel junctions. A specific goal is to understand if the quantum interpretation of experimentally observed macroscopic behavior of Josephson devices is exclusive or if classical dynamics of nonlinear oscillators can equally well explain the observed phenomena.

Grønbech-Jensen is educated at the Technical University of Denmark with a degree in Applied Mathematical Physics (M.Sc.[Cand.] 1989, "Squeezed States of Light") and Physics (Ph.D. [Lic.] 1991, "Phase-locked excitations in the sine-Gordon and related systems"). After a postdoctoral research position in Applied Physics at Stanford University, where he was introduced to biomolecular simulations, he spent seven years in the Theoretical Division at Los Alamos National Laboratory, working on atomic and molecular scale materials modeling, high-performance computing, solitons and phase-locking in nonlinear systems, and numerical algorithm development, before coming to UC Davis in 1999 as a Professor of Applied Science.
