Georg Maierhofer
Henslow Fellow

About Me

I am a Henslow Research Fellow at Clare Hall, University of Cambridge, based in the Applied, Computational and Data Analysis research group at the Department of Applied Mathematics and Theoretical Physics (DAMTP). My research interests cover a range of topics in computational Mathematics, with a particular focus on scientific machine learning and numerical analysis. This includes work on data-driven and structure-preserving methods for differential equations, generative modelling for scientific applications, alongside long-standing interests in highly oscillatory phenomena and computational wave propagation. For more details please see my research page.

In addition, I am also a domain expert and the leader of the working group on Machine Learning for Differential Equations (ML4DE) within Maths4DL. Alongside my academic research, I collaborate regularly with industrial partners on machine learning for scientific and biomedical applications.

Previously, I held a Hooke Research Fellowship in the Numerical Analysis Group at the University of Oxford and a Marie Skłodowska-Curie Fellowship (Project GLIMPSE) at Sorbonne Université in Prof. Katharina Schratz's research group. I completed my PhD as a research scholar of Trinity College, University of Cambridge, under the supervision of Prof. Nigel Peake and Prof. Arieh Iserles.

Scientific machine learning

ICML 2025 spotlight NeurIPS 2025 ICLR 2026

Differential equations underpin most scientific modelling, and machine learning is starting to change how we solve them. I work on hybrid methods that keep the guarantees of classical numerical analysis while borrowing the flexibility of learned models: graph neural networks that relocate finite element meshes, neural hybrid solvers for implicit time-stepping, and data-driven reduced-order models for large-scale dynamics. I also helped design a common task framework for evaluating scientific ML methods objectively. My latest work focusses on improving data-driven models using structure preservation, approximation theory and numerical analysis broadly.

Numerical methods for dispersive differential equations

Leslie Fox PrizeFoCM 2026

Dispersive equations describe a wide range of phenomena, including water waves, ferromagnetism and relativistic wave propagation in particle physics. In my work I design and analyse reliable and physically meaningful numerical methods. This includes research in geometric numerical integration, low-regularity integration, the use of gauge transforms in numerical schemes, and the analysis of long-time properties of such methods.

Highly oscillatory quadrature and wave scattering

Smith-Knight and Rayleigh-Knight Prize

Highly oscillatory problems appear in many physical systems, particularly in the context of wave propagation. Their solution using conventional numerical methods is often prohibitively expensive. My research focusses on incorporating asymptotic knowledge in the design of efficient methods for high-frequency problems. This includes the design of efficient quadrature for hybrid numerical-asymptotic methods and the analysis of regularisation techniques for collocation methods in boundary integral equations.

Machine learning for biomedical applications

ML4H 2025IEEE Trans. Med. Imaging

Machine learning has seen increasing success in biomedical applications, from drug design to medical imaging. These methods lead to a host of interesting mathematical questions often connected to the study of (stochastic) differential equations and numerical methods. My work in this area covers generative models for medical data and drug design as well as applications in imaging.
