Skills
I have a solid background in computer graphics and animation with computational mechanics concepts, such as solid and fluid mechanics, numerical methods, optimization, numerical linear algebra. Besides, I enjoy to combine results from linear algebra, computational geometry and position-based dynamics with the state-of-the-art numerical techniques to develop new efficient methods used to animate virtual face models and address related problems in visual simulations.
C++ / Python skills, and significant work experience with Maya API.
