Over the past 30 years (in both industry and academia) Dr. Fish has made many fundamental and seminal contributions to multiscale computational science and engineering.  Among the most noteworthy contributions are: the s- method for adaptivity, multiscale enrichment elements, homogenization of discrete media, multigrid-based multiscale methods, scale separation-free homogenization methods, reduced order homogenization methods, stochastic multiscale methods, methods accounting for micro-inertia effect, coupling of multiple physical process at multiple spatial and temporal scales, etc. His research 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.


Dr. Fish, the Carleton Chaired Professor at Columbia University, is a recipient of the 2010 Computational Mechanics award from the International Association for Computational Mechanics and the 2005 Computational Structural Mechanics award from the US Association for Computational Mechanics given in recognition for his contributions to multiscale science and engineering.  Dr. Fish is a Fellow of American Academy of Mechanics, United States Association for Computational Mechanics and the International Association for Computational Mechanics. He has written over 200 journal articles and several textbooks including, A First Course in Finite Elements and Practical Multiscaling, both from Wiley. The former has been integrated into curriculum in over 200 universities across the globe.  It has been translated into Japanese and Portuguese and is being translated into Persian and French.

Dr. Fish is a Founder and Past President of a leading multiscale software, Multiscale Design System, with numerous customers in aerospace, automotive, energy, consumer goods and biomedical industries across the globe. The company has been acquired by Altair in 2015 where he currently serves as a Chief Scientific Adviser. Dr. Fish is a Founder and Director of Multiscale Science and Engineering Center originally at Rensselaer and currently at Columbia University. He is a past President of the United States Association for Computational Mechanics.  Dr. Fish is a Founder and Editor-in-Chief of the International Journal of Multiscale Computational Engineering, an Editor of the International Journal for Numerical Methods in Engineering and serves on the editorial board of numerous journals.
