Barbara G. Ryder received the PhD degree in computer science from Rutgers University in 1982, and served on the faculty there from 1982-2008. She is head of the Department of Computer Science at Virginia Tech, where she holds the J. Byron Maupin Professorship in Engineering. She also worked in the 1970s at AT&T Bell Laboratories in Murray Hill, New Jersey. Dr. Ryder's research interests lie in static and dynamic program analyses for object-oriented systems, focusing on usage in practical software tools for ensuring the quality and security of industrial-strength applications. She became a fellow of the ACM in 1998, received the ACM President's Award in 2008, was selected as a CRA-W Distinguished Professor in 2004, and received the ACM SIGPLAN Distinguished Service Award in 2001. She has been an active leader in the ACM (e.g., Secretary-Treasurer 2008-2010, ACM Council 2000-2008, general chair, FCRC 2003, chair ACM SIGPLAN (1995-1997)) and has served as a member of the Board of Directors of the Computer Research Association (1998-2001). She has served as an editorial board member of the ACM Transactions on Programming Languages and Systems, IEEE Transactions on Software Engineering, IEEE Software, Software, Practice and Experience, and Science of Computing. She was general chair of ISSTA 2008.
Andreas Zeller received the PhD degree in computer science from TU Braunschweig, Germany, in 1999, and has served on the faculty of Saarland University, Saarbrücken, Germany, since 2001, where he is now a professor of software engineering. His research interests lie in the analysis of programs and processes, especially the analysis of why programs fail to work as they should. In 2009, he received the ACM SIGSOFT Impact Paper Award for his work on delta debugging as the most influential software engineering paper of 1999. His book Why Programs Fail received the 2005 Software Productivity Award as one of the three most productivity-boosting books of the year. Dr. Zeller has served on the editorial boards of the ACM Transactions on Software Engineering and Methodology and Springer Journal on Empirical Software Engineering. He was program chair of ISSTA 2008.
