Mark Reinhold - Chief Architect of the Java Platform Group
Mark Reinhold is the Chief Architect of the Java Platform Group at Oracle, where he works on the Java SE Platform, OpenJDK, and related projects. Like many in the Java community, he is actually an old Lisp hacker in disguise. Mark holds a Ph.D. in Computer Science from the Massachusetts Institute of Technology, where he worked on garbage collection, compilation techniques, type systems, semantics, and the visualization and analysis of program performance, and where he found enlightenment in the true essence of the lambda nature.
