Raymond Spiteri is a Professor in the Department of Computer Science at the University of Saskatchewan. His areas of research are numerical analysis, scientific computing, and high-performance computing. He specializes in designing efficient time-stepping methods and software for differential equations, especially implicit-explicit and fractional-step operator-splitting methods. He has published over 170 articles in peer-reviewed journals or conference proceedings and has over 6600 citations (Google Scholar). He has co-edited the Springer conference proceedings Mathematical and Computational Approaches in Advancing Modern Science and Engineering (2016) and was principal editor for the book Scientific Computing and Software - Go20 CSCS, Marsalforn, Malta, May 22-26, 2023. Spiteri also serves as associate editor for the journal Applied Numerical Mathematics and co-founded the journal Mathematics in Science and Industry, the flagship journal of the Canadian Applied and Industrial Mathematics Society, for which he served as co-Editor-in-Chief for its inaugural five years.

Siqi Wei is a postdoctoral research scientist at the Environment and Climate Change Canada (ECCC) and an instructor in the Department of Mathematics at Kwantlen Polytechnic University. She obtained her Ph.D in Mathematics in 2025 at the University of Saskatchewan under the supervision of Dr. Raymond Spiteri. Her research area includes time-stepping methods and machine learning methods for differential equations. Her expertise lies in the fractional-step operator splitting methods. She has published six articles in peer-reviewed journals and conference proceedings and has over 30 citations (Google Scholar). She co-organized several mini-symposia at the Canadian Applied and Industrial Mathematics Society (CAIMS) annual meetings. Her research at ECCC focuses on developing hybrid (numerical and data-driven) weather forecast models.
