Manfred Trummer

Manfred Trummer is a Professor in the Department of Mathematics at Simon Fraser University (SFU), part of the Faculty of Science. His research focuses on computational methods in medical imaging, particularly dynamic single photon emission computed tomography (SPECT), and numerical methods for differential equations, including spectral collocation and radial basis function techniques. He emphasizes solving ill-posed problems and improving stability, accuracy, and adaptivity in numerical solutions.

Trummer holds a Ph.D. in Mathematics from ETH Zurich (1983). His work bridges applied mathematics and computational science, addressing challenges in medical imaging reconstruction and high-order numerical methods for differential equations. Notable contributions include advancements in spectral methods, iterative reconstruction techniques for SPECT, and preconditioning strategies for ill-conditioned systems.

His research spans dynamic imaging applications, such as kidney imaging and 4D SPECT reconstruction, alongside foundational numerical analysis topics like matrix factorization, boundary layer resolution, and RBF stability. Recent publications highlight innovations in spectral collocation for mixed functional differential equations and conformal mapping using Szegő kernels.

Trummer teaches graduate courses such as APMA 923 (Numerical Methods in Continuous Optimization). While no specific grants or labs are detailed in the text, his work reflects sustained engagement with interdisciplinary computational challenges in mathematics and medical imaging.
