About

I am a Staff Scientist in the Applied Mathematics and Computational Research Division at Berkeley Lab and a Professor in the Department of Computer Science at KU Leuven. I 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 Quantum Computing. My research interests range from numerical linear algebra and numerical software to quantum algorithms and challenging large-scale linear algebra problems in quantum computing.

Research Interests

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