| I have developed some new courses and offered them to Computer Engineering students (in my previous working school): Their development has been supported by NSF grants. Have developed / offered 3 entirely new Graduate Courses so far: 
 Significance: I created a new track in my department, called Wireless Networking. I thus developed "Wireless Networks" course in Spring quarter of 2003, and offered it to senior students / Graduate students. I have systematically explained the following important topics in class: Wireless Sensor Networks, Cellular Networks, Ad hoc Networks, Bluetooth and Wireless LAN. 
 Significance: To help students understand the lower-layer principle of Radio Communications, I designed this course and offered in 2004 Summer. I covered the Radio propagation details (such as reflection, diffraction, etc.), wireless modulation, CDMA, wireless encoding/decoding, and so on. 
 Significance: Needlessly to say, homeland security is the top concern 
        in the nation. To help students understand contemporary issues, I have 
        designed /offered this course in 2007. The students learned applied cryptography, 
        wireless security problems, corresponding countermeasures. Two security 
        projects (TCP attack and Hash-based security design) further helped them 
        to deeply understand the application of network security.  I have also taught other courses since 2002:
