Jacob Fish

Fish has made many fundamental and seminal contributions to multiscale computational science and engineering.  Among the noteworthy contributions are: scale separation-free homogenization methods, reduced order multiscale methods, stochastic multiscale methods, temporal multiscale methods, methods accounting for dispersion and micro-inertia effects, coupling of multiple thermo-chemo-electro-mechanical processes at multiple spatial and temporal scales, multiscale enrichment methods, upscaling of discrete media, and algebraic multigrid and domain decomposition based multiscale methods. 

Other noteworthy scientific contributions include but not limited to hybrid data-physics driven multiscale methods, high-volume resin transfer molding methods, integrated manufacturing-product design simulation methods, and an additive hypo-elasto-plasticity formulation based on so-called kinetic logarithmic stress rate that was proven to coincide with the multiplicative hyper-elasto-plasticity formulation, and thus enabling to extend a library of exiting infinitesimal inelastic material models to large deformation regimes, that until now, not feasible by existing corotational frameworks.

His research has had tremendous impact on industry: his multiscale methodologies have been employed for manufacturing of GE90 fan blades; environmental degradation of turbo-engines for General Electric, United Technologies, and Rolls-Royce; life prediction of aerospace components for Lockheed-Martin, Northrop-Grumman, and Sikorski; energy absorption of composite cars manufactured by  General Motors; aging and environmental degradation of composites in collaboration with Boeing and GE Aviation; reinforced concrete structures; piezoelectric and ferroelectric materials; various nanotechnology applications ranging from nanodevices to nanomaterials; and most recently, additive manufacturing, fracture of femur, and manufacturing processes.

Fish received a PhD in Theoretical and Applied Mechanics from Northwestern University in 1989. He serves as an editor-in-chief of the Journal of Multiscale Computational Engineering, editor of the International Journal for Numerical Methods in Engineering, and is on the editorial boards of numerous journals. He is a past president of the United States Association for Computational Mechanics (USACM); a Fellow of American Academy of Mechanics, United States Association for Computational Mechanics (USACM), and the International Association for Computational Mechanics (IACM).

Jacob Fish received his BS in structural engineering in 1982 and his MS in structural mechanics in 1985 from Technion – Israel Institute of Technology. In 1989, he graduated with a PhD in theoretical and applied mechanics from Northwestern University. He joined the faculty of Columbia Engineering in 2010.
