I am currently an Assistant Professor in the Computer Science Department at California State Polytechnic University, Pomona (Cal Poly Pomona).
Building good software to solve real world problems is my passion. I am leading the SoftCom Lab to conduct research, consulting and startups with our talented students. Please check out our cool projects.
I am the Co-Founder of the startup company Ziiio - providing the large-scale mobile indoor navigation solutions. Previously, I worked as the Director of Engineering to lead the research and development for another cool startup company - Cloudpoint Labs, which focuses on high-precision 3D augmented reality for mobile platform. Before joining Cloudpoint Labs, I worked for Amazon Silk, the cloud-based split mobile web browser for Amazon Kindle Fire.
I worked as a Post-Doc Research Associate in Dr. Jules White's lab at the Institute for Software Integrated Systems in Vanderbilt University in 2014. I received my Ph.D. in Computer Science in December 2011 from the Department of Computer and Information Sciences at the University of Alabama at Birmingham, and my B.S. degree in Computer Science from Zhengzhou University, China in June 2007. My advisor is Dr. Jeff Gray.

iVote: A Web-based Real-time Classroom Response System
-
Audience response systems such as iClicker have been successfully applied in classrooms to enhance the learning, engagement, and participation of students. Although the dedicated response device is easy to use, a few issues prevent it from being adopted at a larger scale: 1) students have to purchase and remember to bring the device to classrooms; 2) the device is not flexible to support a diverse range of questions (e.g., iClicker only support questions with a maximum of 5 answer options); 3) the device does not support two-way interactions (e.g., the device cannot receive feedbacks). To address these issues, we have built a web-based response system that can be directly used in any of the mobile devices or computers. Instructors are enabled to customize questions, view real-time response status, and send feedbacks to students.

High-Precision Mobile Augmented Reality
-
Hybrid 4-Dimensional Augmented Reality (HD4AR) provides high-precision and robust mobile augmented reality using millimeter-level alignment of cyber information with real-world imagery. A user can snap an image of the physical world, upload the photograph to a cloud-based server, and receive an augmented image back that visualizes cyber-information on top of it in seconds. This is a commerialized university research project based on computer vision, mobile and cloud computing.

Amazon Silk
-
A key challenge with mobile web browsers is that the browsing performance is always limited by the networking and computation capacity available to the device at a particular location of use. The Amazon Silk mobile web browser, originated from a research project, is based on a split architecture, where certain browser processing is performed in Amazon’s powerful cloud servers and the client devices only handle the lightweight computation related with rendering and UI control.

Model Transformation By Demonstration (MTBD)
-
When models become the first-class entities for constructing software systems, the models often need to be transformed and evolved to adapt to various system changes, such as model refactoring, model scalability, and aspect-oriented modeling. Instead of using the traditional approach to write transformation programs to automate the evolution process, MTBD is an end-user programming solution that allows end-users (e.g., domain experts and non-programmers) to demonstrate how a transformation should be done on a concrete example by directly editing the source models. The MTBD engine records user operations and automatically infers and generates the executable transformation pattern that can be applied generically to any source model. MTBD has been applied to automate a number of model evolution scenarios. Users do not need to have a programming background or understand the abstract metamodel definitions.

Time-Triggered Systems Modeling Language (TTS-ML)
-
TTS-ML was designed to support the development and maintenance of distributed time-triggered communication systems used by the Siemens eCar project (i.e., the electrical vehicle research project conducted by Siemens Corporate Research). The modeling language allows for efficiently modeling physical and logical aspects of the system as well as quality of service requirements (QoS). A model completion step using scheduling and arbitration algorithms derives missing communication information. A code generation step creates target platform- and controller-specific code from the model automatically.

UWoN (User Workflow Notation)
-
UWoN is a modeling environment to model user workflow process in user interface (UI) design, which was applied to a healthcare intervention application supported by Siemens Corporate Research. The modeling environment takes the graphical workflow model as the input, generates the simulation code based on the rich and rigorous semantics of the Little-JIL process definition language, which helps UI designers to better analyze and evaluate the UI performance.

Automax
-
Automax is a model-based development environment implemented to support robotics development for industrial robotics assembly lines. Automax enables a domain expert (who is not a computer scientist) to model robot action sequences with timing requirements, and automatically generate embedded robotics controlling code. This project has been conducted with Bullheller Consulting, a software firm whose core robotics software is deployed in over 2000 robots used at the Mercedes-Benz plant USA in Alabama.

Live Model Transformation By Demonstration (Live-MTBD)
-
When a large group of users are enabled to contribute to model evolution activities using MTBD, reusing model transformation patterns at the appropriate scenario becomes an essential issue to enhance knowledge reuse. Live-MTBD is an extension to the MTBD framework that contains a set of “live” features: 1) live demonstration provides a new type of demonstration approach that encourages creation of model transformation patterns; 2) live sharing makes all generated patterns available to users for reuse, and 3) live matching helps users to reuse the correct pattern at the appropriate time.
Publication: [ICMT '11]
Model Transformation By Demonstration Debugger (MTBD Debugger)
-
The capability of MTBD is undermined if users cannot debug a generated transformation pattern at the same level of abstraction to which the demonstration was performed. Thus, an MTBD Debugger was developed based on the MTBD execution engine, enabling users to step through the transformation execution process and track the model’s state during a transformation. MTBD Debugger focuses on end-user friendliness, so the low-level execution information is hidden during the debugging process.

A Model Engineering Approach to Tool Interoperability
-
The integration of various tools is a common requirement throughout the software development process. It is often desirable to consult several tools that perform similar functionalities in the same domain to obtain different perspectives and results to assist design and maintenance decisions. In many cases, tool interoperability requires the generalization of tool-specific data, which requires homogenizing the data such that intellectual assets can be shared through a common framework (e.g., the integration of results from various clone detection tools). This tool demonstration summary presents a software language engineering solution technique that uses Model-Driven Engineering to address tool interoperability. A specific focus of the project is to apply model transformation to the task of homogenizing different data formats among similar code clone detection tools.
