Ran Wolff

Biography:

I completed my Ph.D. studies in the Computer Scienc Department of the Technion - Israel Institute of Technology. Then, did a post-doc at  UMBC  and back at the Technion. Previously I did my B.A. in computer science at the Technion and then worked for several years with Amdocs and Chip-Express. 

Research:

My research spans three main areas:

• Data mining in large-scale distributed systems, e.g., peer-to-peer and sensor networks or grid systems. 
• Privacy preservation in data mining.
• Distributed information systems and their management.
