A visiting research fellow at the Dept. of circadian neuroscience (Oxford university) where I learned analyzing data from actigraphy from Prof Russel foster, Kathirina Wulff and Prof.Guy Goodwin. A few years later I was awarded the AASM minifellowship award twice and attended Penn sleep center in 2012 and Pittsburgh sleep center in 2014. I managed to submit several capacity building research projects to initiate the foundation step of the Mansoura University Sleep Lab. Very recently I have been awarded the gift of honor from the Egyptian medical syndicate for my efforts in sleep medicine. This activity was educative to physician assistants and employees of the university.
