My academic career has been involved in several fields of biology and we can consider me as a hybrid. I  have participated in a large-scale multidisciplinary of biology related to both basic and applied research projects.
My Ph.D studies were centered around the comprehension of the mechanisms of reproduction and developmental  biology using the freshwater planarian Schmidtea mediterranea as a model.

My postdoctoral studies were balancing between two different fields of research: a) Reproduction and developmental biology and, b) Evolutionary biology. The last research axis which is mainly focusing on the biosystematics and molecular phylogenetics of planarians has been developed under the supervision of Prof. Marta Riutort (University of Barcelona, Spain) and Dr. Ronald Sluys (University of Amsterdam, Netherlands).
I then moved to the King Saud University where I gradually focused my work, with respect to the first field of basic research, in a new direction of applied research: "The fetal programming research". We are particularly interested in the effect of some environmental perturbations, mainly nutrition and pollution, on gametogenesis and pregnancy, and thus on the heath of the new generations. Indeed, the gametogenesis and the early fetal development are critical determinants of adult physiology. In fact, some cases of adulthood diseases can be attributed to an adverse embryonic environment that leads to permanent changes in growth, metabolism and the vasculature of various organs, which predisposes the child to adulthood diseases. We are also interested to expand knowledge about the mechanisms of actions and areas of applications of selected candidate molecules of plant extracts in control of gametogenesis, in particular female reproductive processes. For that, rats and rabbits represent excellent models for studying and testing new drugs. Using these models, we try to examine in vivo and in vitro effects, mechanisms and areas of possible application of plant and seed components in control of different female reproductive processes such as ovarian cell proliferation, ovarian cell apoptosis, ovarian follicle growth and maturation and embryo development.
