Structural Biophysics

Lionel Mourey

Group Leader

The activity of our group goes from fundamental to applied research in the fields of structural biology, biophysics and screening. Our expertise covers all the steps from engineering to biochemical, biophysical and structural characterization of challenging macromolecular assemblies and macromolecule-ligand complexes with great interest in pharmaceutical and biotechnological research.

An important objective of our team is to be a major player in the development of molecular biophysics, integrative structural biology, and ligand screening and design.

Our group develops four research topics (described below). Our research benefits from strong collaborations with laboratories in the Toulouse area, including teams at IPBS, as well as national and international networking. This reflects our commitment to providing the scientific and medical communities with tools that we believe play a major role in answering relevant biological questions, helping to combat diseases and furnishing bio-based tools to tackle technological challenges. In line with this, our biophysical and crystallographic equipment is part of the Integrated Screening Platform of Toulouse (PICT), a national IBiSA platform run under the quality management system standards ISO 9001-2015 and NF X50-900. With two Professors and four Associate-Professors, our group is also strongly involved in teaching and training through research.
