Yvonne McGrath, iTeos Therapeutics, Chief Scientific Officer

"Lennart worked in the iTeos bioinformatics team for more than two years after a period of consultancy. In his time at iTeos, Lennart built a bespoke iTeos data portal to allow iTeos scientists to access, analyze and visualize complex integrated research and translational medicine data. Throughout the process, Lennart was hyper-responsive to the needs of the scientists, creating user-friendly tools and providing excellent training and guidance as the project was rolled out. The project was a resounding success as judged by the feedback of stakeholders and the broad usage of the platform which was monitored as part of success metrics."

Jo Van Dorpe, Ghent University Hospital, Head of the Department of Pathology

“As the promoter of Lennart’s doctoral thesis, I came to know Lennart as a brilliant bioinformatician, which resulted in several first-authored papers published in journals with impact factor 10 and above. Lennart is an analytical thinker, but what truly stood out was his creativity in writing papers and the artwork he produced for his thesis and publications, which was highly appreciated.”

Maarten Braspenning, BISC Global, Founder & CEO

"Lennart is one of the most hard-working bioinformaticians I have had the pleasure working with. Regardless of the project and complexity, he always gave it 100% and ensured the job got done on time. On top of his skill and go-getter attitude, he also has great skills in breaking down a project in manageable tasks and estimating timelines, ensuring that before the start of a project, customers would have a clear idea on what to expect. Finally he also has great communication and management skills, allowing him to manage and supervise projects on top of executing them. In short, I can recommend anyone to work with Lennart.”

Francesco Strozzi, iTeos Therapeutics, Director Bioinformatics

"Lennart was part of my team for almost 2 years at iTeos Therapeutics and he built, from the ground up, our internal R&D Data Portal. This platform hosted more than 600 different datasets for preclinical and translational medicine research, spanning different data types from bulk and single cell RNAseq, to spatial proteomics and transcriptomics, IHC, Flow Cytometry, Metabolites, Cytokines and Chemokines dosage, as well as clinical data from ongoing trials. The work Lennart performed on this platform was outstanding, giving the researchers the possibility to properly organize the datasets of their experiment, allowing them to browse and analyze complex data, and generate presentation and publication-ready visualizations, without having to write a single line of code. The unique blend of data management, data analysis and data visualization skills Lennart possesses it's truly impressive, along with his professionalism, responsiveness and high-quality work he carried out during his time at iTeos."

Lynn Verbeke, Excelra, Director International Bioinformatics

“Lennart consistently delivers high-quality work with great attention to detail and always meets deadlines. He has demonstrated deep technical expertise and a professional, client-focused approach across multiple projects. He has a clear passion for making data more interpretable and easier to handle. Lennart’s ability to balance initiative with active listening makes him a highly effective and dependable collaborator who gets things done.”

Björn Menten, Ghent University Hospital, Center for Medical Genetics Ghent

"I had the pleasure of supervising Lennart during his PhD, where he proved to be an exceptional bioinformatics researcher. Highly independent, fast, and reliable, Lennart consistently delivered high-quality work and was a pleasure to collaborate with. He developed powerful tools like WisecondorX and PREFACE, which we still use daily in our postnatal and prenatal genetic analyses. His expertise, structured approach, and calm, professional manner make him an excellent partner for any bioinformatics project."
