Welcome to the Len Research Group Website!

The Len Research Group, led by Prof. Dr. Christophe Len at the Université de Technologie de Compiègne (UTC), France, is dedicated to developing innovative and alternative approaches to organic chemistry, catalysis, and advanced chemical technologies. Our research focuses on the design and implementation of sustainable, efficient, and intensified chemical processes, with a particular emphasis on continuous-flow chemistry combined with alternative activation technologies, including microwave irradiation, ultrasound, and mechanochemistry.

Through an interdisciplinary approach, we aim to rethink conventional chemical processes, explore new reaction pathways, and develop innovative solutions for the synthesis and transformation of chemicals, fuels, and advanced materials. A central ambition of our research is to bridge the gap between academic innovation and industrial applications, accelerating the transition from fundamental discoveries to practical, scalable, and sustainable technologies.

By combining chemical innovation, process intensification, and the valorization of chemical resources and waste streams, we strive to contribute to the development of a more sustainable and resource-efficient chemical industry.
