Background

  • Staff Member at Sandia National Laboratories, Livermore, CA
  • Post Doctoral Associate at Sandia National Laboratories, Livermore, CA
  • University of Wisconsin – Madison, Ph.D. in Mechanical Engineering
  • University of Wisconsin – Madison, M.S. in Mechanical Engineering
  • Katholieke Universiteit Leuven, Belgium, B.S. in Mechanical Engineering

What Matters to Me

My main research interest and expertise is in enabling predictive simulation in science and engineering, with the goal of effectively using all available knowledge in data, theory, and expert opinion to provide more confidence in answers to relevant questions in complex systems. This encompasses uncertainty quantification, Bayesian methods for parameter estimation and model selection, resilient computing, as well as stochastic multiscale coupling methods, applied to systems ranging from atomistic flow simulations, and human immune system signaling pathways, to continuum microfluidics, cyber security, quantum computing, high performance computing, and up the scale to climate models.

Besides my technical interests, I care tremendously about Equity, Diversity, and Inclusion (EDI) in our society in general, and in the scientific community in particular. I am engaged in many efforts to provide equity in the opportunities available to anyone regardless of their race, gender, sexual orientation, or other identities. The goal is for everyone to be able to achieve their full human performance and feel empowered and welcomed to bring their best creative selves to work.
