- Cellular biochemistry and molecular biology: membrane structure; expression of eukaryotic metabolic genes, especially those of lipid metabolism in peroxisomes and in mitochondria.
- Cancer prevention by pro-apoptotic natural compounds.
1- Bioenergetics (1971 to 1975) Sulfhydryl residues of the inner mitochondrial membrane; involvement in the respiratory chain and in oxidative phosphorylation (FEBS lett, 1975).
2- Membrane proteins (1974 to 1985) Purification of the D-3-hydroxybutyrate dehydrogenase of the inner mitochondrial membrane, a phospholipid requiring enzyme; role of lecithin in the active site (Biochemistry, 1980, Biochem J 1985).

Cloning of a peroxisomal bi-functional enzyme (Biochem J, 1998). Creation of null mouse deficient in peroxisomal thiolase, a model of genetic diseases (Biochimie, 2004, 2009, 2011).
5- Cancer chemoprevention (2000 to present) as protecting and preventing agents against cancer (from 2000 to present) Studies of the pro-apoptotic properties of resveratrol a grape phytoalexin; application to chemosensitization of colon tumors (JBC, 2003, Oncogene, 2004, Curr Drug Targ, 2006, Int J Cancer, 2009); transport and bioabsorption of resveratrol (BBRC 2004, DMD 2007); Regulation of mi-RNA as tumor supressors or tumor inducers by resveratrol (Carcinognensis,2010, Biochem Pharmacol, 2010).
