My name is Elyas Nasimdoust I'm an M.S.c student of physics (optics and laser) at the Institute for Advanced Studies in Basic Sciences (IASBS) in Zanjan, IRAN. After graduating from high school, I decided to study physics. In 2015, I was accepted to B.Sc. physics at the University of Guilan. After 4 years, that is, in 2019, I decided to continue my studies in optics and laser at IASBS. I am currently a sophomore M.Sc. student of Optics and Laser at IASBS. My project is under the supervision of Dr Ali-reza Moradi and the topic of my thesis "Controlling the directed collective motion of particles with speckle field".
