His main research have been on tumor suppressor hDlg which includes an in-depth characterization of the combinations of hDlg isoforms present in multiple tissues and cell lines to correlate the presence of specific alternatively spliced insertions with a specific function of this tumor suppressor. He also studies the perturbation of hDlg distribution in two skin disease: psoriasis, characterized by a hyper-proliferation of basal cells, and Darier's disease, characterized by blisters resulting from the loss of cell adhesion in the supra-basal layers.
He is a founding member of BioVisions.
