Research interests:

  • Structural and functional organization of chromatin.In a series of studies has showed how functional properties of chromatin correlates with their the ability to fold under  ionic strength increasing and length of  the nucleosome repeat .
  • The role of covalent modifications of histones and transcription factors in the realization of a cell programs.Described a new mechanism of regulation of p53 through methylation of lysine by Set9 methyltransferase. Set9 specifically methylates a single amino acid of the protein p53 in the carboxyl-terminal regulatory domain. Methylated p53 confined to the nucleus and this modification has a positive effect on its stability. The  role of methylation of p53 on the cell cycle arrest when DNA damage had proved.
  • I am interested inthe role of non-coding RNAs in the differentiation and maintenance of the differentiated state of cells.
