Dr. Collberg received his Ph.D. from the Department of Computer Science at the University of Lund, Sweden. He spent the next five years at the University of Auckland, New Zealand, and is currently an Associate Professor at the University of Arizona. His primary research area is the protection of software from reverse engineering, tampering, and piracy. In particular, the SandMark tool (sandmark.cs.arizona.edu) developed at the University of Arizona is the premier tool for the study of software protection algorithms. Dr. Collberg has also worked on the automatic retargeting of compilers, a search-engine for computer scientists (algovista.cs.arizona.edu), no-cost static linking (slinky.cs.arizona.edu), and a tool for self-plagiarism detection (splat.cs.arizona.edu). He is the recipient of research grants from the National Science Foundation and the Air Force Research Lab and has served on the program committees for ACM Programming Language Design and Implementation, the Information Hiding Workshop, DRMTICS, and others. Dr. Collberg's US patent 6,668,325 "Obfuscation techniques for enhancing software security" (assigned to InterTrust Technologies) is a major building block for current and future Digital Rights Management technologies. Dr. Collberg's expertise on code obfuscation and information hiding will be leveraged in studying client tamper- protection and innocuous token-stream transfer. His work on software watermarking is useful starting point into client instrumentation.
