PROFESSIONAL EXPERIENCE

GOOGLE, Mountain View, CA Software Engineer 2008 Present

Build common infrastructure and systems to combat online abuse, including spam, porn, etc.

PAYPAL, AN EBAY COMPANY, San Jose, CA Staff Software Engineer 2005 2008

Worked in PayPal's Trust And Safety Engineering department to develop world-class products to fight

online fraud.

Participated in the PayPal Security Key project, which involve a geographically diverse team of over

140 and multiple third-party companies. Designed and implemented core functionalities of this

feature to enable second factor authentication on PayPal.

Led a team to build PayPal s advanced risk rules engine. It allows intuitive rules authoring, fast and

flexible rule release, and highly efficient real-time rule execution and evaluation.

Designed and implemented PayPal s Risk Analytics Dynamic Datasets framework to allow quick

upload and use of heterogeneous datasets that have varied structure and size.

CIRL LAB, THE JOHNS HOPKINS UNIVERSITY, Research Assistant 2001 2005

P AGE 1

Participated in the NSF VICs project. Investigated efficient and robust vision-based techniques to model

dynamic gestures as well as composite gestures for human-computer interaction.

Proposed a novel and efficient shape/motion descriptor to capture hand motion.

Investigated such methods as neural network, extended HMM, finite-state machines to model

dynamic gestures.

Proposed efficient algorithm to model composite gestures using graphical model and HMM.

Composite gestures are sequences of heterogeneous gestures including static, dynamic, and

parameterized gestures.

Designed and implemented a flexible vision-based HCI platform. Carried out a human factor

experiment on this platform. The experiment involved sixteen subjects and twelve gestures.

HAPTIC EXP. LAB, THE JOHNS HOPKINS UNIVERSITY, Research Assistant 2002 2003

Designed and implemented the VisHap augmented reality system, which uses visual tracking to

seamlessly integrate force feedback with tactile feedback to generate a complete haptic experience.

DEP. COMPUTER SCIENCE, JOHNS HOPKINS UNIV., Teaching Assistant 2000 2001

Worked as TA for three courses from 2000 to 2001, including Computer Vision, Algorithms,

Intermediate Java Programming.

COMPUTER VISION LAB, TSINGHUA UNIVERSITY, Research Assistant 1997 2000

Participated in the face detection, recognition and identification project. Implemented efficient algorithms

to carry out face recognition on a database of over 500 people. The system consisted of such key modules

such as constrained camera rectification, face detection, facial features extraction, and efficient matching.

BLUE BOX INC., BEIJING, CHINA Software Engineer 1998-1999

Led a team to design and implement a business management system. Development tools used include

PowerBuilder, SQL, MS Visual Studio and InstallShield.

NASOFT INC., BEIJING, CHINA Software Engineer 1998

Joined a team of fifteen engineers to implement the Bank Credit Registration System. This distributed

system consisted of such modules as server database management, bank operator interface, Internet

access support, and middleware. Such tools as SQL, Sybase PowerBuilder, Visual Basic and HTML were

used during development.
