I work at the intersection of numerical analysis, applied mathematics, computational mechanics, artificial intelligence, dynamic systems and data-driven modeling; from mathematical foundations in wave propagation and boundary element methods to applied problems in additive manufacturing, structural health monitoring, intelligent process control and human centric manufacturing systems. Digital Twinning under Industry 4.0 and Industry 5.0 is the goal.
