About Bart VandereyckenChristian LubichNicola GuglielmiNicolas GillisPunit SharmaVolker Mehrmann

Nicola Guglielmi has been a full professor in Numerical Analysis at Gran Sasso Science Institute School of Advanced Studies since 2018 and a visiting professor at the Courant Institute University of Geneva University of Zurich McGill University and Georgia Institute of Technology. His research focuses on numerical methods for delay and functional differential equations eigenvalue optimization with applications to matrix nearness problems and data science switched and non smooth dynamical systems joint spectral characteristics of sets of linear operators implementation issues for stiff and implicit delay equations stability properties stiff problems and the development of related code. He edited with L. Dieci the volume Current challenges in stability issues for numerical differential equations. CIME Lecture Notes in Mathematics 2082 Springer Cham 2014. With Ernst Hairer he is the co-author of the software RADAR5. He was awarded the New Talent Prize (SciCADE Fraser Island) in 1999 and a young researcher prize (Volterra Centennial Tempe) in 1996. Christian Lubich is a professor of Numerical Mathematics at the University of Tübingen. In his research he develops and analyses numerical methods for time-dependent problems including ordinary differential equations and parabolic partial differential equations geometric flows wave propagation and quantum dynamics. Among the methods and techniques proposed and studied by him and his coauthors convolution quadrature exponential integrators modulated Fourier expansions for highly oscillatory problems and dynamical low-rank approximation have gained wide acceptance. He is the author with Ernst Hairer and Gerhard Wanner of Geometric Numerical Integration: Structure-Preserving Algorithms for Ordinary Differential Equations (Springer 2002 2006) and of From Quantum to Classical Molecular Dynamics: Reduced Models and Numerical Analysis (European Mathematical Society 2008). He was awarded the SIAM Dahlquist Prize in 2001 and was a plenary speaker at the International Congress of Mathematicians in 2018.
