MIT. He designed the original EMACS command set and was the first
person to port TeX.
At Oracle labs, he is responsible for research in language design
and implementation strategies, and architectural and software support
for programming languages. His recent work at Sun has included network
design for processor clusters, circuit designs for floating-point
arithmetic and interval arithmetic, and proposals for improvements to
the Java Programming Language such as generic types, operator
overloading, and constant classes. Currently he is Principal
Investigator of the Oracle Labs Programming Languages Research Group,
which is working on Fortress, a next-generation programming language
for scientific and multicore computing.

techniques for over 7 years, following the Behavior-Driven Development
(BDD) ideas since the first rumblings in 2005. Lately, he has been
actively mentoring others in the BDD workflow, as it pertains to
day-to-day engineering practices, such as TDD and executable
In 2010, Corey hosted a series of Code Retreats throughout the USA and
abroad, including Belgium, Sweden and Australia, in which he shared
his ideas surrounding the agile process and test-drive development. In
2011, he continues this activity, focused on helping developers
improve their skills through practicing the fundamentals of software
Over the past year, he has been actively working on his own startup,
exploring how quality development practices provide value at such a
