Research Experience

 

University of Rochester, Rochester, NY,

Sept. 2005 - present

Research  Assistant

Studied the coordination of hand and eye movements and built a computational model for anticipatory eye movements in human-object interactions. Designed and conducted human experiments, and constructed a data-driven model based on working memory decay and anticipated object reference orders.

 

Palo Alto Research Center (PARC), Palo Alto, CA

May 2005 - Aug. 2005

Summer Intern

Worked in Ubiquitous Computing Area of Computer Science Lab on automatic recognition of conversational floors and behavior modeling in computer mediated conversations. Collaborated closely with sociologists and computer scientists to study acoustic, prosodic and lexical characteristics as well as timing characteristics of multi-user social conversations. Designed and implemented computational models to detect various key features in conversation modeling.

 

University of Rochester, Rochester, NY

Jan. 2005 - May 2005

Research Assistant

Investigated computational modeling of subtask recognition and planning in natural tasks. Designed and conducted human experiments. Proposed and implemented a general framework for automatic subtask identification and a probabilistic model of subtask scheduling.

 

University of Rochester, Rochester, NY

Dec. 2003 - Dec. 2004

Research Assistant

Implemented the Visual Routines model and developed a complete virtual human vision system with script-controlled behavior. Identified a set of basic cognitive primitives for human-object interaction and designed a language to program the behaviors of a graphical human figure in virtual reality.

 

University of Rochester, Rochester, NY

Jan. 2003 - Dec. 2003

Research Assistant

Developed a humanoid avatar with basic real-time vision in virtual reality, on a distributed platform using high speed FPGA chips. Augmented a commercial human simulation software package with binocular vision and biologically realistic eye movements. Designed FPGA circuits to implement steerable filters which enable real time iconic visual search.

 

Fudan University, Shanghai, China

Sept. 2000 - Jul. 2001

Research Assistant

Investigated the application of fractal theory and evolutionary computation in automatic generation and optimization of fuzzy control systems. Applied cooperative coevolution in a novel way. Studied the encoding of fuzzy membership functions, explored various genetic operators, and fine-tuned fitness functions with my colleague. Achieved the world best result in the classification of the standard IRIS data set.

 

Fudan University, Shanghai, China

Sept. 1998 - Jul. 2000

Research Assistant

Designed a dynamic distributed genetic algorithm which can better overcome premature convergence. Applied asymmetric migration technique to produce the optimal tradeoff between speed and diversity by dynamically adjusting niche sizes.

 

Development Experience

 

Bao Steel Research Center, Shanghai, China

Feb. 2000 - Jun. 2000

Software Architect

Lead a development team in a joint project between Fudan University and Bao Steel Group, a fortune 500 company. Communicated with research staff at Bao Steel and designed the software part of a real time monitoring system for coke oven research. Managed software development and testing. Implemented the user interface with Microsoft Visual C++.

 

Changhai Hospital, Shanghai, China

 

Part-time Programmer

Developed patient registration software for the Department of Radiology. As the only programmer, worked independently. The software facilitated the crosslink between the patient database and the x-ray image database.

 

Fudan Network Information Center, Shanghai, China

Nov. 1996 – Feb. 1997

Part-time Programmer

Worked in a team developing electric plant monitoring systems. Carried out database design and maintenance using Microsoft SQL Server and Visual Basic. Wrote system manuals.

 

Teaching Experience

 

University of Rochester, Rochester, NY

Sept. 2002 - Dec. 2003

Teaching Assistant

TAed two courses in 3 semesters: Computer Programming (twice) and Data Structure. Gave two lectures in each semester, graded projects and exams with other TAs.

 

Bell College, Jiangyin, Jiangsu Province, China

Sept. 2000 - Jun. 2001

Adjunct Instructor

Taught course C++ Programming to 200 sophomores. Designed and graded all homework, quizzes and exams.

 

Jason Training Center, Shanghai, China
