The American Chemical Society Division of Chemical Information announced that Prof. Matthias Rarey has been selected to receive the 2025 Herman Skolnik Award for his contributions to the development of foundational algorithms in Cheminformatics, education & training in the field of Cheminformatics and his activities bridging academia and industry.
Prof. Rarey’s research concentrates primarily on methods for ligand-based and structure-based molecular design. His early work focused on the development of novel techniques for flexible ligand-protein docking and his postdoctoral research resulted in the Feature Tree concept, an approach to the representation and searching of small molecules that has found particular application for exploring combinatorial chemistry and fragment spaces. More recent studies have led to novel approaches for the drawing and visualization of molecular structures, chemical patterns, and biological macromolecules, for de novo design, for the analysis of protein binding sites and torsion-angle distributions, and for 3D shape similarity. Examples of systems derived from his research include the FlexX protein-ligand docking program, PoseView for generating 2D diagrams of complexes with known 3D structures, FTrees for similarity searching in chemical spaces, HYDE for scoring hydrogen bond and dehydration energies in protein-ligand complexes, and ReCore for scaffold-hopping in lead-discovery programs. Recently, SpaceLight and SpaceMACS were added enabling topological similarity searching in combinatorial make-on-demand catalogues like Enamine REAL for the first time. Within SPP2363, Matthias Rarey and Frank Glorius work together on the synthetically feasible extension of chemical fragment spaces with machine learning (Project SAFE).

With the support of an SPP scholarship, I was able to join the Cernak group at the University of Michigan for a 6-month research stay. It was an amazing experience to learn new techniques for high-throughput experimentation, library synthesis and direct-to-biology approaches. It was great to see how the group collectively used expertise in synthesis, chemoinformatics, software development, medicinal chemistry, and biology to identify and synthesize molecular libraries for testing in biological assays. Personally, I had the chance to advance the concept of late-stage saturation, which was introduced in a collaborative project with our group in Germany to facilitate library synthesis.
In addition, I had the chance to work on chemoinformatic approaches in reaction enumeration to identify and prioritize valuable and synthetically relevant reactions that are yet to be developed. I am very thankful for the warm welcome and support I received from the entire Cernak group during my stay. Besides the fantastic research opportunities, I am also really grateful for the chance to explore Michigan and the US and build many friendships in the process. I would like to thank Prof. Tim Cernak and the SPP2363 for this great opportunity.

Thanks to the SPP scholarship, I had the amazing opportunity to spend three months on a research stay abroad at the University of Michigan in the United States. It was an absolute pleasure to work alongside Prof. Timothy Cernak and his group. The group is made up of talent from a variety of disciplines, including chemists, pharmacists and software engineers. Their focus on high-throughput synthesis was particularly relevant to my research on reaction networks for synthesis. We also started a project in collaboration with Prof. Paul Zimmerman's group to investigate the use of large language models (LLMs) in predicting activation energies to aid reaction discovery. We used techniques such as one-shot and few-shot learning, as well as fine-tuning of different LLMs using previously published work from the Zimmerman group on reaction discovery computations on B, C, N, O ring formation using NH3BH3 and CO2 as data.

While research was a priority, the university offered a lot of different recreational activities that I was able to enjoy with my newly found friends. I am sure that this collaboration will continue in the future. Thanks again to the SPP 2363 to make all of this a reality, it was an incredible experience!

I am very grateful to have been granted the SPP2363 scholarship for a research stay in the group of Dr. Antonia Mey at the University of Edinburgh, UK. During the 6 weeks I had the fantastic opportunity to learn and adapt Machine Learning concepts from the field of Drug Discovery onto enzymatic catalysis prediction. The Mey group is well known for its explorations of Artificial Intelligence techniques on biomolecular modelling. I was highly impressed by the group’s expertise and particularly enjoyed a close collaboration with Rohan Gorantla who is a final year PhD student in the group. During my visit we explored new concepts that will help with enzymatic catalysis ML tasks. Together, we developed and applied concepts of Positive Unlabeled Learning on the prediction of enzyme reactions. This is now being benchmarked on existing tools and we are hoping for a joint publication. In the next step we want to explore Active Learning strategies for enzyme discovery campaigns to evaluate proteins fitness and usability for small molecule enzymatic catalysis. We are all looking forward to further collaboration and are very grateful for the opportunity provided by SPP2363.

The SPP2363 scholarship for research abroad allowed me to stay almost three months at the Massachusetts Institute of Technology in Cambridge MA, USA. This opportunity helped me to grow not only scientifically but also personally. I spend my time at the MIT in the group of Prof. Rafael Gómez-Bombarelli (short: Rafa) in the department of material science and engineering. Rafa is an established professor for computer enhanced molecular discovery and design as well as molecular machine learning. Part of his research focus lays on machine learning potentials, generative models and fundamental science related to molecular machine learning. All these fields are perfectly in line with my own PhD project in the SPP2363.
During my stay I worked on ML potentials to speed up transition state search algorithms. The final goal is to predict highly accurate transition state barriers in a fraction of the ab initio calculation time. My direct supervisor during my stay was Dr. Johannes Dietschreit, a postdoc in Rafa’s group. In plenty of discussions Johannes explained to me the different approaches to generate a dataset, training of the potential and active learning cycles to achieve my goal of building a functioning ML potential. In the process of trying out the different approaches my overall understanding of this area of machine learning, which was new to me before my research stay, drastically increased. In addition to improvements in my own PhD project, I was able to learn a lot about the broad range of research projects in Rafa’s group. Either by personal scientific discussions or based on group meeting talks on a weekly basis, I learned a lot about general concepts of molecular machine learning and challenges that can occur while studying them.
The scientific aspects made my research stay to a memorable experience. On top of that, I was able to grow personally based on rich cultural exchange and the variety of activities that Cambridge and Boston had to offer.

Thanks to the scholarship for PhD students to stay abroad of the SPP2363, I had the opportunity to expand my research projects for several weeks at the Vanderbilt University, Nashville, Tennessee, USA. During that time, I worked together with several members of our partner lab, and especially, with the research assistant professor Benjamin (Ben) Brown, who specialized in the development and application of computer-aided drug design methods. Ben Brown is one of the main developers and contributors of the BioChemical Library, in short BCL, which employs machine learning algorithms for more than 15 years. Furthermore, he is an expert for optimizing drug candidates with both traditional and deep learning methods. In many fruitful discussions, we evaluated the current paradigm shift in the field and discussed the future of machine learning, especially for small molecules. Furthermore, during a special session about “Recent Developments and Technologies in ML”, I had the opportunity to listen to presentations from various researchers and directly discuss it with the lab members. A highlight was definitely the talk “Towards Data-Centric Graph Learning for Real-World Applications”  from Assistant Professor Tyler Derr from Vanderbilt, where he presented his current research projects and machine-learning approaches.

This internship in Nashville gave me valuable insights outside of my day-to-day research environment and work. Of course, the personal and direct communication facilitates the exchange of research ideas, especially during hiking or group events in Nashville. The international lab, its environment and the welcoming/open nature of America captured and embraced me and round off an exciting time. I am really grateful to the SPP2363 for this unique and rewarding opportunity.

Combining machine learning and physical knowledge: Junior research group develops models for industrial production

Fabian Jirasek is granted the new Emmy Noether Junior Research Group "Hybrid Thermodynamic Models" by the German Research Foundation (DFG), which will be established at RPTU Kaiserslautern. The group will develop novel thermodynamic models to predict the fluid properties of mixtures. The knowledge of these properties is essential for the chemical industries, e.g., for process optimization and establishing new production routes that rely on renewable instead of fossil raw materials.
Mixtures are omnipresent when producing chemicals and medicines, but also in developing new batteries, e.g., for e-cars. "Understanding the properties of these mixtures is of central importance for basically all processes in chemical engineering, from the reaction to the purification of the target products," says Fabian Jirasek, who is a Junior Professor for Machine Learning in Process Engineering at RPTU Kaiserslautern. "They are the basis for design and optimization of efficient processes."
Investigating all conceivable combinations of substances and the influence of parameters, such as temperature and pressure, in laboratory experiments is not feasible due to the abundance of possibilities. "Therefore, we rely on our models to also predict the fluid properties of non-measured substances and mixtures as well as at non-measured states," explains Jirasek. In thermodynamics, such models have been established for decades. But thanks to machine learning (ML), a subfield of artificial intelligence, research today has entirely new possibilities. "ML techniques will revolutionize thermodynamic modeling," Jirasek is certain. In the new project, Jirasek and his team will develop hybrid models combining machine learning and physical modeling. "We assume that machine-learning methods will require significantly less data by exploiting the available physical knowledge," he continues. "This will also create trust and acceptance for the novel models if they or their predictions satisfy known physical laws."
The DFG's Emmy Noether Programme is aimed at outstandingly qualified young researchers. The goal is that they can thereby qualify for a professorship by independently leading a junior research group.
Fabian Jirasek studied bioengineering at the Karlsruhe Institute of Technology and earned his doctorate in thermodynamics at Kaiserslautern. He then researched at the University of California at Irvine before moving to TU Munich. Since the fall of 2020, he has held the Junior Professorship for Machine Learning in Process Engineering at RPTU Kaiserslautern, funded by the Carl Zeiss Foundation.

Cover on The Journal of Chemical Physics

The latest semiempirical tight-binding method for electronic structure calculations by the Grimme group (S. Grimme, M. Müller, and A. Hansen) has made it to the cover of The Journal of Chemical Physics! The method, named PTB, is excellently suited for the generation of descriptors in the context of modern machine-learning approaches based on quantum-chemical features. As PTB is available for all elements up to Radon (except for lanthanides) and is a non-self-consistent two-step method, it provides consistent and robust results throughout large parts of the chemical space. The method will be publicly available in the open-source xtb program package - give it a try!

In C&EN's June cover story, Matthias Rarey highlights how computational tools help to navigate chemical spaces and virtual libraries in the search for new drugs.

Connecting chemical building blocks allows drug hunters to explore a much bigger chemical space than before. The challenge is to narrow this field of compounds to something manageable. To do that, chemists are turning to new computational tools to navigate this increasingly huge chemical universe, and they are combining technologies. Experts say these new approaches should speed up the identification process, and industry is investing time and money to optimize the hunt.
