Biographical Sketch

I am a Ph.D. and engineer specialized in computer science and applied mathematics.

I did my Ph.D. on the measure and localization of numerical errors due to floating-point arithmetic in a high-performance computing context.

I am currently working with NERSC to help port the TOAST software framework (used to study the cosmic microwave background) to the new Perlmutter supercomputer and, in particular, port it to graphic processors (GPU).
