Postdoctoral Research Fellow

As a biochemist from the Lebanese University, I decided to pursue a research master’s degree in molecular biology with emphasis on immunology. Being a challenge taker, my AUF and CEDRE doctoral grants allowed me to travel to Paris and achieve a co-tutelle PhD degree in Life Sciences from Paris Saclay and Saint Joseph Universities-Beirut. I worked on the regulation of telomerase by the long non coding RNA H19 in acute Promyelocytic leukemia. Building a research publications record continued with a first post doc experience at USJ that was followed by a second opportunity at The Lebanese American University where I had the chance to join the Human genetics lab and recently being an instructor of two biology courses. This allowed me to successfully accomplish my career goals until present.
