This is a handful of projects I've worked on over the years. I'm fortunate that much of my work at IBM Research is either open source or publicly disclosed and I can discuss the work in detail.

Visualization SDK for Spherical Displays

I lead a project to create a software development kit for creating visualizations on specialty (spherical) displays. This Java and OpenGL-powered framework enables developers to easily create specialized presentations on these displays without needing to understand the complex transformation mathematics. Third-party "extensions" can use declarative, REST-based JavaScript, or native Java APIs to create and orchestrate visualizations. For interactive systems, customizable user interfaces are developed with HTML/JavaScript and served by an embedded Web server.

The system powers a 60" OmniGlobe spherical display currently in the IBM Almaden Research Center lobby. The project is closed source.

Healthcare System Interoperability

My first major project at IBM actually began when I was an Extreme Blue intern. Two students and I created a Web service (SOAP) API for the Eclipse Open Healthcare Framework called the OHF Bridge. The OHF Bridge is a platform-independent method for electronic medical record systems to easily share medical records and other patient information with standards-based document registries and repositories. The tools have been used widely adopted in third-party applications, including IBM products.

The OHF Bridge was initially contributed to the Eclipse Foundation's Open Healthcare Framework project. In 2008, the project was migrated to the Open Health Tools IHE Profiles project. The source is fully open sourced under the Eclipse Public License.

Framework for Modeling Infectious Disease

Recently I've been contributing to the development of Eclipse Foundation's Spatiotemporal Epidemiological Modeler (STEM) project. STEM is a framework that enables public health officials to create, simulate, and analyze models of emerging infectious diseases. The STEM project is hosted by the Eclipse Foundation and is fully open sourced under the Eclipse Public License.

Various Other Projects

• Healthcare ESB - Enterprise framework for healthcare interoperability.
• Interoperability tools for IBM's 3D Electronic Medical Record Viewer. Now licensed to Nhumi AG.
• Medical literature analysis tools to identify relevant publications for a patient's conditions. With Corey W. Arnold of UCLA.
