Experience

1. Technical Expert Aerospace Vibroacoustics

   Keysight Technologies

   Jan 2022 — Present · Cleveland, OH, US

   Continued in the same role following the integration of ESI Group with Keysight Technologies in May 2025.→ Provides technical expertise for structural dynamics and acoustic simulations for aerospace applications. Activities focused on customer specific projects, presales studies and training development.→ Takes part in engineering software development planning sessions ensuring customer feedback is accounted for. Participates in developing feature acceptance criteria.→ Management and technical coaching of a team of three application engineers.Methodology development:→ Simulation resource and time requirement prediction based on large data sets of previous models solve log using Bayesian regressions.→ Development of a Bayesian optimization for rapid probabilistic estimations of overall level on frequency response coupled finite element-boundary element models.→ Shock simulation using the virtual mode synthesis and the finite element method (implicit and explicit non-linear transient formulations).→ Damping projection models using the modal strain energy.Feature prototyping using the Python environment as part of the methodology development, allowing for early acceptance from the customer before feature development.
