I build numerical and machine-learning models, and I care most about how they perform in speed and fidelity on GPUs and HPC clusters: CUDA-accelerated kernels, MPI-based parallelization, and predictive methods such as Reservoir Computing, applied to complex dynamical systems. The systems have ranged from rotating turbulence and squeezed states of light to industrial sensor time-series. I judge a model on more than accuracy: whether its results reproduce, whether its evaluation holds up, what it costs to run, and whether its predictions can be explained.
