Pros
As a graduate student you have the opportunity to obtain a world class engineering degree that will leave you with a variety of different career opportunities. The PhD program provides a challenging platform to develop your analytical and communication skills. Unlike the PhD stereotype, my experience has helped greatly develop both my written and vocal communication skills. The some programs are interdisciplinary and allow students to learn and syntesize concepts from a varitey of traditional disciplines. Georgia Tech also offers a multitude of resources, including business and language classes, which most graduate students can utilize to obtain a well rounded education.
Cons
Like most PhD programs, a timely and successful completion of the degree requires a substantial amount of work after regular hours and during weekends with little monetary compensation. Perspective students need to be aware of the time and financial commitment required.
