Professional Accomplishments

Medical	Developed the clinical decision support system for Eclipsys Sunrise Clinical Manager product. Sunrise Clinical Manager is the industry leading patient care software system for hospitals. Using expert systems technology, expert rules alert physicians to abnormal situations. Roger Corman architected, designed and implemented the clinical decision support system, which allows doctors and other medical experts to encode their medical logic in a language called Arden This clinical decision support system is considered to be the most advanced in the industry, offering real-time feedback and alerting capabilities, and was the first commercial Arden implementation on the market. Bill Gates discusses this system in his book Business @ the Speed of Thought pp. 343-346. Developed HL7 interfaces (message parser, message generator) for Eclipsys products. All incoming and outgoing patient data goes through these interfaces. Developed CALINX Lab Tool for California HealthCare Foundation (CHCF) . This tool parses, converts and analyzes lab messages using the CALINX standard (HL7-based). Developed the ELINCS EDGE Tool for California HealthCare Foundation (CHCF) . This tool generates and parses ELINCS messages.
Compilers and Development Tools	Developed and continue to maintain the Arden compiler in Eclipsys Clinical Decision Support , which continues to lead the industry with new functionality. It currently implements the Arden 2.5 (current) HL7 spec. Corman Lisp , a Common Lisp compiler and development environment for Win32, which outperforms the competition on a variety of benchmarks. Corman Lisp, the only Common Lisp compiler fully supporting multi-threading on Windows platforms, has achieved a serious following of developers actively working to use and enhance the product. Corman Lisp includes state-of-the-art garbage collecting, full Win32 and COM support, and can parse and import C header files. PowerLisp: Common Lisp for Mac OS . This was the first PowerPC native Common Lisp compiler for the Mac OS. Includes full source code. Compilers and interpreters for Postscript, Arden Syntax. Assemblers and code generators for Intel, PowerPC and 680x0 processors.
Web Architect	Chief architect of eHealth.com , the number one online health insurance seller. This system, built using J2EE, comprises thousands of JSPs, servlets, Oracle, Weblogic, Apache and Solaris servers. It operates 24/7 and continually receives top ratings from Keynote for performance and availability. Architect of ImagePump image viewing software for rendering high-resolution and multi-resolution images on the web.
Imaging	Developed dozens of products incorporating 2-D image processing, image retouch, page layout, animation, color transformations and 2-D rendering. Products included Time Arts Lumena, Trapper, Island Paint and NPS ImageExpress.
