BIO
Hands-on aerodynamicist with experience in supersonics, hydrodynamics, automotive and aerospace, who loves building the infrastructure of the future. I thrive on experimental fluid-dynamic studies to find novel solutions to complicated problems, while leveraging simulation tools and low fidelity analysis to back up the experiments. I am happy expanding my work to include all other aspects of engineering for a good product design. On my own time I love finding the confluence of science in baking.
