Current research

My professional interest lies in agro-ecosystem and biological stress, where I am particularly interested in crop weeds. I am currently focusing on the study of among and within genetic variation of Sinapis arvensis populations from Algeria and their probable resistance to some herbicides widely used in Algeria. 

My PhD thesis is entitled “Crop weeds: Phytodiversity and means of control”. My thesis includes two parts: (i) the genetic diversity of wild mustard weed (Sinapis arvensis) from wheat crop fields and non-crop fields from several regions in northern Algeria, which is conducted under the supervision of professor Heinz Müller-Schärer, and (ii) natural means of weed control using plant allelopathic substances in vitoin vivo and in situ

During my master, I worked on mycoherbicidal effects of phytopathogenic fungi isolated from weeds as basis of weed biocontrol. This working experience raised my interest in weed science and control.
