While the full-time regular faculty members teach
most courses, some specialized courses are taught by
local professionals (adjunct professors) who have particular
expertise. While the Telecom faculty members are all
active researchers, we all believe research and teaching
are intimately coupled. If you come here, you will
take classes from distinguished faculty members, who
advance the state of the art and who have high expectations
of their students.
While we teach the details of Telecommunications, we
focus on the 'big picture'.
The Telecom faculty believes that: 'The
system is the solution'. If you put yourself
in our hands, we will teach you to be a network architect,
a systems engineer. |
