Welcome to Guoning Chen's Homepage

Guoning Chen Postdoctoral Research Fellow at SCI Office: WEB 2815 Contact:

I have moved to the University of Houston to start a tenure-track position at the Department of Computer Science. Here is my new webpage .

I am looking for well motivated graduate students to work on various visualization research projects that will accelerate the knowledge discovery and help to make a better life.

About me

Hello, my name is Guoning Chen. I have started a Postdoctoral position at Scientific Computing and Imaging (SCI) institute at the University of Utah. My mentor is professor Chuck Hansen. At SCI, I am working on multiple projects. One is to develop efficient techniques for the analysis of toroidal magnetic fields for a SAP (Supplemental Application Partnership) project led by Allen Sanderson. I am also working on projects in geometric modeling, aiming to develop efficient algorithms to generate 2D and 3D meshes for visualization purpose and physically-based simulations. In the meantime, I continue working on vector and tensor field analysis and control for various data visualization and computer graphics tasks.

Before joining SCI, I earned my Ph. D. degree in Computer Science from Oregon State University in 2009. My advisor was Dr. Eugene Zhang. During my PhD work, I had been working on vector field visualization, analysis, and design for scientific visualization and computer graphics applications. I am also interested in tensor field analysis and design, geometry modeling and processing, texture synthesis, and animation.

I received a B.S. degree in Information and Communication in 1999 from Xi'an Jiaotong University and a M.S. degree in Control Theory and Engineering/Computer Application (advisor: professor Taoshen Li) in 2002 from Guangxi University in China. I worked as an instructor in the Computer Science department of Guangxi University from 2002 to 2004.  

Here is a version of my current CV in pdf.             

Research Interests and Philosophy

My research interests lie in scientific data visualization and computer graphics with emphasis on vector and tensor data analysis using topological-based methods for many engineering applications and various computer graphics tasks, such as, geometric modeling, geometry processing, non-photo-realistic rendering, computer animations, video editing, and digital arts. Vector fields are widely used to represent various dynamical systems that are involved in many important engineering applications, including computational fluid dynamics (CFD), automatic and aircraft design, mechanical engineering, climate study, oceanography, earthquake engineering, fusion science, and medical practice. Analyzing vector data stemming from these applications help the domain experts efficiently identify dynamics (or features) of interests, such as stagnant points and recirculating flows, that are critical for understanding the involving systems. I have worked with the domain scientists from the previously mentioned areas to help understand and present their large-scale and complex vector data. In the meantime, the features of interests that help characterize the vector fields are some sub-sets of the data, which are geometric in the nature. This allows us to develop efficient algorithms and interface to design and control these features to achieve the vector fields with desired behaviors. This processing is known as vector field design , an important tool for many important computer graphics tasks. To that end, I have bridged my research topics in visualization and computer graphics with an effective methodology, that is, the results of the analysis of (vector) fields can be applied to devise effective means to control and model them. In addition, many other more complex data, such as tensor and higher-order tensor fields, can be decomposed or converted to some sorts of vector fields during analysis. For instance, the analysis of tensor fields can be partially accomplished through the analysis of their corresponding eigen-vector fields. Therefore, the analysis of vector fields provides the foundation for understanding more complex data. In the near future, I would like to extend my existing work on 2D steady vector data analysis and control to more complex settings, such as 3D, time-dependent (i.e. unsteady), or tensor and higher-order tensor data. I will also look forward to addressing emerging visualization and computer graphics problems with more challenging requirements.
