I am a Ph.D. student in Computer Engineering at Science and Research Branch, Tehran, Iran. Under the supervision of Dr. Amir Masoud Rahmani. Also, I am a member of the Security and PRIvacy Through Zeal (SPRITZ) research group, Padua, Italy. Under the supervision of Prof. Mauro Conti. I am working on BigData especially Hadoop, the tool for analyzing and visualization the data. In fact, I research on Hadoop as an aim not as a tool for solving bigdata problems i.e. my research field is at the infrastructure level: energy efficiency, fault-tolerance, load balancing, scheduling, resource provisioning, performance, and security.
