Jacob Fish

Jacob Fish is the Robert A.W. and Christine S. Carleton Professor and Chair of the Department of Civil Engineering and Engineering Mechanics at Columbia University. He directs the Multiscale Science and Engineering Center and leads Columbia's Computational Science and Engineering initiative (iCSE), coordinating 65+ faculty. With 35 years of pioneering research, he specializes in multiscale computational methods bridging aerospace, automotive, and healthcare industries.

His research integrates multiscale computational science with applications in:

• Homogenization and reduced-order methods for complex materials
• Stochastic modeling of heterogeneous systems
• Coupled thermo-chemo-electro-mechanical processes
• Data-physics driven frameworks for industrial processes

Recent work emphasizes AI-enhanced modeling for composites, porous media, and environmental systems.

His 15 most recent publications (2023-2025) demonstrate strong trends toward:

• Data-physics integration in manufacturing (e.g., resin transfer molding)
• Multiscale environmental applications (canopy flows, CO2 mineralization)
• Advanced numerical methods (discontinuous Galerkin, solver-free homogenization)
• Digital twin development for composite lifecycle management

Scientific Awards & Honors:

• 2018 JSCES Grand Prize
• 2010 IACM Computational Mechanics Award
• 2005 USACM Computational Structural Mechanics Award
• 2003 Rensselaer Research Award
• Fellowships: AAM, USACM, IACM
• Two Best Paper awards

He founded the commercial Multiscale Designer software suite (250+ global clients) and secured major grants including an NSF-DFG collaboration on thermoplastic interfaces. His textbooks are used in 200+ universities worldwide.

Leads the Multiscale Science and Engineering Center focusing on industrial-scale computational challenges and mentors researchers through Columbia's iCSE initiative. Former President of USACM and current IACM Vice-President for the Americas.
