Domains of interest

My background is in biology (biochemistry and biophysics), with a marked interest for physical chemistry. Since I entered research, my work has focused on integral membrane proteins, with two major types of research:

Understanding the structure and function of some specific proteins, mainly:

  • the nicotinic acetylcholine receptor;
  • bacteriorhodopsin;
  • the major proteolipid from myelin (PLP);
  • cytochrome b6f.

Developing general methods or concepts, applicable to most if not all integral mem­bra­ne pro­teins. In particular:

  • understanding the mechanisms that determine the folding, assembly and stability of those membrane proteins whose transmembrane domain is made up of α-helices;
protein



Two-stage folding model of α-helical membrane proteins. From Popot and Engelman, 1990.

  • exploring new methods of sequence analysis;
  • developing novel chemical tools for handling and/or studying membrane proteins, in particular two families of surfactants, fluorinated surfactants and amphiphilic polymers ('amphipols').

My work currently focuses on developing amphipols and their applications.
