His research mainly focuses on Symbolic and Algebraic Computation (SAC), automatic code generation, Internet Accessible Mathematical Computation (IAMC), polynomial factoring and GCD algorithms, enabling technologies and classroom delivery of Web-based Mathematics Education (WME), and parallel and distributed SAC.

[1] His doctoral thesis, supervised by Joel Moses, is entitled "Evaluation of Definite Integrals by Symbolic Manipulation".

Wang joined Kent State University in 1977 and began to establish the computer (CS) subject in the Department of Mathematical Sciences.

He developed and published mathematical theories and new algorithms for GCD and factoring of univariate and multivariate polynomials, over the integers and algebraic extensions.

[7] [8] The central breakthrough in Wang's polynomial factoring algorithms lies in p-adic lifting (Hensel's lemma).

This idea and other ingenious methods, such as leading coefficient determination, combine to make Wang's polynomial factoring algorithms powerful and practical.

[10] He studied the importance of C++ in terms of bridging real world applications and addressing basic concepts of object-oriented programming.

[11] In his work regarding HTML5, Wang studied HTML5 markup language and DOM, structuring of Web documents and forms, and important JavaScript APIs related to HTML5.

He explored XML and PHP/MySQL, and also proposed page templates, user login, database access, session control, and form processing.

[15] His approaches are based on standard Web protocols and technologies including HTML5, CSS3, Javascript, DOM, PHP, MySQL, Apache, MathML, SVG, XML, AJAX, and HTTPS.
