For more than 25 years, Karen has worked in information technology starting out as a mainframe programmer, developer, DBA, data architect, author, researcher, educator and consultant. Having used Oracle since the early ’90s, she began teaching others how to use Oracle over a decade ago. Today she is focused primarily on Oracle performance optimization, particularly in the areas of SQL tuning and understanding the Oracle optimizer.
Karen's years of experience have meshed well into optimizing applications running on the Exadata platform. Her deep knowledge of how SQL works and how Exadata features require a change in approach to many optimization efforts allows her to understand what to do and when to do it regardless of whether the environment is Exadata or non-Exadata.
Karen is the co-author of three books from Apress: Beginning Oracle SQL, Expert Oracle Practices: Database Administration from the Oak Table and Pro Oracle SQL. She's a frequent speaker at conferences and user groups, a member of the OakTable Network, and an Oracle ACE.
