I just passed Ph.D. defense on March 14, 2008. This page serves as an HTML version CV and the PDF version is available here (36.1KB).

Research Interests

My research interests include software variability modeling and code generation, configuration management systems, business rule engines and languages, etc.

My disseration topic is Rhizome: A Feature Modeling and Generation Platform for Software Product Line. We developed a feature modeling and automatic feature code generation platform called Rhizome. Our feature modeling language is used to capture high level feature design choices, then our template-based code generation engine automatically implements these design choies as source code. Our work is a practical end-to-end solution for feature modeling and generation in software product line. Rhizome tackles the core problem of making connections between designs at semantic level and source code at implementation level.

Before the final version is produced, you can read the disseration draft from here. For those of you with limited time to go through 200+ pages, you can read my defense slides (61 pages) instead.

Experience

• Graduate Student Researcher, University of California, Santa Cruz (Sep 2001 - March 2008)

Rhizome: Feature Modeling and Code Generation Platform: Designed a feature modeling language and a template-based code generation platform for software feature modeling and automatic code. Generated a product family of online exam Web application systems that integrates Spring, Wicket, Hibernate, and MySQL.

Bamboo: Automatic Generation of Version Control Systems: Domain analysis with a large group of version control systems such as SCCS, RCS, CVS, ClearCase, Perforce and Subversion. Designed and implemented a selector-style code generator that automatically produced simple version control systems based on different feature model configurations.

• Summer Intern, Content Management Group, IBM Almaden Researcher Center, San Jose, CA (June 2004 - Aug 2004)

  Business Rule Processing Gateway: developed a gateway to validate business rules for XForm-based customer forms. This is part of an automatic paper form scanning and processing system that IBM was developing for customers. Business rules cover both client and server side validation. Designed Event-Condition-Action rules and implemented gateway using ABLE (Agent Building and Learning Environment), a rule engine developed by IBM. Applied this gateway in a demo auto-loan application and filed a patent based on the design and implementation.

• Summer Intern, China Telecom, Changshu, China (Aug 1999 - Oct 1999)

  System Administration: developed a server-side module that generated electronic phone bills for customers to pay bills online or over the phone. Also helped design and maintain Yu Cheng Hotline (http://www.cs.js.cn), a famous portal site for Changshu city.

Project Demos (sorry, no audio)

New! Rhizome demo video: In this video, we show the whole process of generating source code, importing the code into Eclipse, compiling and running the generated Web application (a fammily of online exam systems). The video can be found here (15m01s, 45MB).

VarML demo videos: The first video shows graphical XML schema for VarML language: VarML schema introduction (2m55s, 4.63MB)

The second video demonstrates a graphical editor for VarML language that we developed using Eclipse Graphical Modeling Framework (GMF) and Graphical Editing Framework (GEF): VarML GUI demo (11m39s, 16.07MB)
