The core focus of the Scientific Machine Learning (SciML) Group is AI for Science.

As such, the mission of the group is to explore how the use of Machine Learning and other AI technologies can help scientists analyse the vast amounts of experimental data now being routinely generated by the large experimental facilities at the Rutherford Appleton Laboratory (RAL) and STFC’s Harwell campus. With the rapid development in detector technologies and the emergence of new experimental techniques, such as cryoEM, and accelerated detection rates, there are now major challenges for scientists to manage and process very large datasets. We develop and apply various state-of-the-art machine learning or AI technologies to accelerate the process of scientific discovery. SciML routinely works with beamline scientists from various facilities at RAL, such as Diamond Light Source, Central Laser Facility , ISIS Neutron and Muon Source, Technology Department, and NERC's Centre for Environmental Data Analysis and their JASMIN service.  The group provides a national AI computing service for the Alan Turning Centre and STFC researchers working on AI for Science along with various training courses on scientific machine learning.  

SciML is a partner with the Alan Turing Institute in their ‘Data Science for Science’ theme, and is a Turing Hub at Harwell. We have a number of strong links and collaborations with various national labs in the US.  Our activities at RAL complement the predominantly industry-focused work of the ​Data Science Group at the Hartree Centre, and the two groups collaborate in several joint activities. ​​​

Recent Highlights

SciML Publication


Our latest research looks at combining graph neural networks (GNNs) with Gaussian processes to perform active learning of materials properties. GNNs provide a powerful intuitive route to featurising material structures, while Gaussian processes provide estimates and uncertanties that allow us to identify the optimal next material to investigate in order to improve the model generalisability.

SciML at I2NS

SciML work with ISIS was recently presented at the Innovative Inelastic Neutron Scattering workshop in Autrans, France. Andy Sode Anker and Keith Butler presented the latest work on using machine learning to analyse and understand inelastic neutron scattering data. Read more about the work that we are doing with ISIS in the SciML and ISIS projects page.

Welcoming new group members

The SciML team are delighted to welocme our latest group members. Hattie Stewart, Michael Norman and Ben Winter from the Data Intensive CDT, as well as Andy Sode Anker from Copenhagen University are all joining us for 6 month projects to work on a varity of exciting topics. We are really looking forward to the exciting work that we will do over the next 6 months.

GraphCore System & Training Workshop


In anticipation of the arrival of a new Graphcore system at STFC, RAL, the SciML team has collectively attended a three day virtual training on how to effectively leverage the GraphCore's TensorFlow and PyTorch software frameworks to significantly speed up machine learning workflows. Throughout the course, the team was able to road test two GraphCore systems and gain experience scaling ML workflows. This training will be crucial for utilising the forthcoming Graphcore IPU-M2000 system with 4 x Colossus MK2 IPUs. This system will augment SCD’s and STFC’s AI computing capabilities, namely, PEARL and SCD-Cloud,  and is expected to provide an additional 1 PetaFlops of computing power towards AI applications.

SciML Projects

SciML has a wide range of active projects using machine learing to enhance fundamental scientific research. We work with a diverse range of partners based at the Rutherford Appleton Laboratory and beyond. Find out more about more about our portfolio of projects on our Research Projects Page.

​SciML Seminars

​​We run a weekly seminar series welcoming talks covering a broad range of topics in machine learning and its applications to science from both internal and external speakers. Information on past and upcoming seminars can be found here​.

Training Courses

​As a group, we offer various training courses focussed on AI for Science. For more information on training, please contact us​.

​​PEARL AI Service​

The PEARL service, provided through a collaboration between The Alan Turing Institute and Science and Technology Facilities Council, is a state-of-the-art GPU-based system for AI and machine learning research. The system includes two NVIDIA DGX2 nodes, ​and a 600TB storage, linked by a fast interconnect. The system has several thousands of GPU cores, and a large amount of memory to support most AI or machine learning operations, such as training on large datasets. You can apply for access to PEARL here.​
