Arpit Tiwari is a Ph.D. holder in Theoretical and Applied Mechanics and a Master of Science in Mechanical Engineering from the University of Illinois at Urbana-Champaign. With a Bachelor of Technology degree in Mechanical Engineering from the Indian Institute of Technology, Bombay, Tiwari has significant expertise in computational fluid dynamics (CFD) and numerical methods for multiphase flows.

Tiwari has worked in various organizations, including Gamma Technologies, LLC, Caterpillar Inc., and the University of Illinois at Urbana-Champaign. At Gamma Technologies, LLC, Tiwari serves as a Staff Computational Fluids and Thermal Systems Development Engineer, where he is responsible for designing, developing, implementing, and testing advanced mathematical models and computational schemes for flow and thermal analysis of automotive and engine subsystems.

Tiwari's research is often focused on developing efficient and stable numerical schemes for flow and thermal simulations. His recent efforts in the development of multiphase flow solutions have resulted in a publication in AIAA, further showcasing his expertise in areas like adaptive mesh refinement (AMR), FORTRAN, C++, and MATLAB, and parallel programming (using MPI) to speed up simulations.

Before joining Gamma Technologies, LLC, Tiwari worked with Caterpillar, Inc, where he was responsible for engine design and optimizing flow and thermal behavior of automotive and engine subsystems using commercial CFD packages. As a graduate research assistant at the University of Illinois at Urbana-Champaign, Tiwari explored Lattice Boltzmann Method (LBM) based CFD analysis of micro-fluidic systems and compressible multiphase flows, applying techniques to predict tissue damage due to bubble-cluster collapse in therapeutic ultrasound. His research has been featured in top-notch journals, such as Journal of Fluid Mechanics and Journal of Computational Physics.
