I am interested in diversity, biology and genetics of oomycete plant pathogens (Belbahri et al., 2006; 2007; 2008). My research also include development of genetic transfer methods in Phytophthora (Riedel et al. (2009) and involve the description of emerging diseases in different regions of the world (Daughtrey et al., 2006; Romero et al., 2007; Belbahri et al., 2008; Moralejo et al., 2009, Józsa et al., 2010). Present research activities also include biotechnological applications of fungal enzymes (Khlifi et al., 2009 and 2010, Maalej-Kamoun et al., 2009, Mlaik et al., 2009 and 2011) and the annotation of the genome of Heterobasidion annosum.
