Teaching Styles


Slides plus black board


Slides can convey more information in an organized way


Blackboard is better for equations and prevents you from not coming.


A lesson from last semester: math


Course Website


Print handouts with
3
slides per page before you come


Homework assignment and solutions


Project descriptions and preliminary codes


Feedback


Too fast, too slow, small class advantages.


Presentation, English, …

Reasons to be my students


Wireless Communication and Networking have great market


Usually highly paid and have potential to retire overnight


Highly interdisciplinary


Do not need to find research topics which are the most difficult
part.


Research Assistant, Stipend


Free trips to conferences in Alaska, Hawaii, Europe, Asia…


A kind of nice (at least looks like)


Work with hope and happiness


Graduate fast
