Research Profile

Dr. Wei Zeng’s research centers on applying modern geometry to solve real problems in engineering and biomedicine, especially on geometric analysis and its applications. 

Recently, she has been working on the following projects related to cyber security:

  • Biometrics in Cyber Security. Biometrics is the science and technology of measuring and analyzing biological data. In information technology, biometrics refers to technologies that measurezeng-biometrics and analyze human body characteristics, such as DNA, fingerprints, eye retinas and irises, facial patterns, voice patterns, and hand measurements, for authentication purposes. The incorporation of biometrics into cyber space will greatly enhance the information security.  The pipeline of biometric verification (bio-data acquisition, preprocessing, shape representation, feature extraction, comparison, and recognition, and shape evolution analysis) and its combination with cyberspace applications (e.g., user recognition and localization, information assurance) will be explored. The novel algorithms on imaging and shape analysis will be invented.
  • Geometric Analysis in Networks. The graphical network data are ubiquitous today, such as wireless sensor network, social network, Internet, power grid, and any other wired or virtual zeng-geo1 zeng-geo2networks in different industries. Usually these networks are with a very large scale, containing a huge amount of nodes and complicated topology (highly non-planar). More sophisticated tools from modern geometry can be applied to benefit the main applications in networking, such as delivery guaranteed routing, load balancing, efficient information distribution, network dynamics analysis, sensor localization, deployment, and so on. Ricci flow theory is fundamental in geometric analysis, can handle arbitrary surfaces and graphs, and offers a powerful and practical tool towards the above real applications.
