Marina Vatkina is a Principal Member of the Technical Staff at Oracle Corporation, formerly Sun Microsystems. She first got involved with Java technology when she was working on a Sun software product called Java Blend, whose goal was to equip programmers with a tool for developing business applications entirely in the Java language without needing to know much about relational databases or Structured Query Language (SQL).
During the last ten years Marina has been responsible for several areas in the implementation of Sun's - now GlassFish's - Java EE application server, including persistence, transaction manager, and the EJB container. Her technical focus relates to Java EE server-side technologies, and she has shared her enthusiasm with the Java community when blogging and speaking at the JavaOne conference.
Marina is currently the Spec Lead for JSR 345, Enterprise JavaBeans 3.2. She is also an Expert with the newly restarted JSR 236, Concurrency Utilities for Java EE. She holds a Masters degree in Applied Math and Computer Science from MIIT, a university in Russia. For fun, she enjoys cooking and tasting good food, travelling when she has time, listening to classical music, and going to art museums.
