About

I am a Research Scientist in the Computational Research Division at Berkeley Lab and received my PhD in Engineering Science: Computer Science (2015) at KU Leuven from which I also hold Master degrees in Mathematical Engineering (2010) and in Archaeology (2011).

My main research fields are Applied Mathematics and Scientific Computing. My research interests range from numerical linear algebra and numerical software to quantum computing and quantum algorithms.

Research Interests

  • (Nonlinear) Eigenvalue Problems
  • Numerical Linear Algebra
  • Model Order Reduction
  • Numerical Software
  • Quantum Computing
