Ram Chillarege

Dr. Ram Chillarege, is the inventor of Orthogonal Defect Classification (ODC). He has helped implement ODC at several Fortune 500 companies in the US, Europe, and Asia. Savings from ODC, reported by companies range from tens of millions of dollars to hundreds. Ram is an IEEE Fellow and recipient of the IEEE Technical Achievement Award for ODC. He founded the Center for Software Engineering at T.J. Watson Research, and spear headed the creation of IBM's corporate-wide Test Council. An initiative that inserted technology, transformed practice and yielded significant business impact. He currently chairs the IEEE Steering committee for Software Reliability Engineering.

He received a PhD from the University of Illinois, Urbana Champaign in Electrical and Computer and Engineering, BE and ME from the Indian Institute of Science, and BSc in Physics and Mathematics from the University of Mysore. Ram is the author of ~50 peer reviewed technical articles, and has served on a few steering committees, editorial boards, several program committees, and the alumni board of the University of Illinois Department of Electrical and Computer Engineering.  Ram chaired the ISSRE 2009 conference, and co-guest edited the September/October 2010 issue of the Security and Privacy magazine. Recently (2013) he was awarded the IEEE Computer Society Meritorious Service Award, "for chairing the ISSRE Steering Committee, and leadership in keeping ISSRE a vibrant and exciting conference".

Ram's workshops tap on this vast experience to inform, coach and energize your software engineering and management teams. His training programs have touched thousands of engineers word-wide.
