Two Barba-group Ph.D. students successfully defended their doctoral dissertation this week. Congratulations to them!
- Anush Krishnan came to Boston University on 2009, after completing a Dual Degree (B. Tech & M. Tech.) in Aerospace Engineering at IIT Madras, Chennai, India. He has worked on development of immersed boundary methods (IBM) for solving Navier-Stokes equations at moderate Reynolds numbers, and application to the aerodynamics of flying snakes. Anush developed cuIBM, a two-dimensional IBM code using Nvidia GPUs with CUDA, and PetIBM, a 3D IBM code using the PETSc parallel CPU library.
- Christopher Cooper arrived at Boston University shortly after, in Spring 2010. He has a mechanical engineering degree from Universidad Técnica Federico Santa María—also Prof. Barba's first alma mater—in Valparaíso, Chile. Christopher has worked in the development of fast boundary element methods (BEM), using trecode and fast multipole algorithms, and application to biomolecular electrostatics and biosensors. He developed the PyGBe code, a BEM solver using Python and GPUs via CUDA and PyCUDA.
Anush starts a new job immediately as CFD engineer in Exa Corporation while Christopher is taking a position as faculty of the Mechanical Engineering Department at Universidad Técnica Federico Santa María!
