Marc Baaden's homepage


Welcome ! This site is about recent research in computational chemistry. My main focus is the development of a novel interactive approach to molecular modeling, taking advantage of recent progress in the field of virtual reality combined with HPC. This project is described here: FVNano project. Another area where the above method as well as more familiar ones can be applied concerns the investigation of large conformational changes and mechanical properties of macromolecules.

There is now a YouTube channel with movies related to research described at this website. You can visit my YouTube channel here!

Have a look at the latest publications on the recent publications page. The full publication list and an annotated full publication and communication list in French are also available. Some documents are deposited in my open access archive on HAL. There is a page with selected posters, too. The most actively maintained part of this website are the project and overview pages. These pages include my latest news blog.

Latest News: Spotlight on general anesthetics binding to GLIC, a nicotinic receptor homologue.

In a letter to Nature (20 January 2011), we describe crystal structures, functional measurements and molecular dynamics simulations of GLIC in complex with propofol and desflurane, two general anesthetics. This links to the corresponding Nature article website. This work is also featured by two Faculty of 1000 evaluations (Must Read and Recommended).

Previous work in PNAS featured a one microsecond molecular dynamics simulation of the pentameric ligand-gated ion channel GLIC. This simulation actually showed some interesting modifications of the anesthetics binding cavity. The free open access article is available here, and here is a short movie (Nury et al., PNAS, 107, 2010, 6275-6280). This work was rated Must Read by the Faculty of 1000.

The first work on the GLIC system was published in the 2009 January issue of Nature, where the crystal structure of an open form was described. We used additional molecular dynamics simulations to characterize this state. Here is a link to the Nature website, and here is a short movie. There is also a press release. (Bocquet et al., Nature, 457, 2009, 111-114). Faculty of 1000 rated this paper twice, either as Must Read in F1000 Biology or as Recommended in F1000 Medicine.

Bacterial Outer Membrane Proteins - about enzymes and iron transporters

While I was an EC Research fellow at Oxford University, I worked on computational studies of the bacterial transporter protein FepA in membranes (Marie Curie Fellowship MCFI-2000-01210). This project is related to J. D. Faraldo-Gómez's work on the ferric hydroxamate receptor A (FhuA).

The simulations were extended to other outer membrane proteins of beta-barrel shape, in particular the enzymes OmPLA and OmpT. On a broader level methodological aspects such as simulation convergence were studied in collaboration with a number of colleagues.

Keywords: anti-bacterial drugs, transport proteins, molecular modelling


I started working on biological systems in Mark SP Sansom's group at the Laboratory of Molecular Biophysics, University of Oxford, where I was a postdoctoral fellow during the years 2001 and 2002.

Currently I am a researcher ("Chargé de recherche de 1ère classe") working in Paris at the Institut de Biologie Physico-Chimique. My work is carried out in Philippe Derreumaux's group in the "Laboratoire de Biochimie Théorique" of the CNRS (UPR9080).
