Electrical Engineering

You should submit your applications online

The selection is a two-stage process for each thematic area of research. For the sake of convenience, we use some short keywords to identify each of these areas listed below

Thematic Area Name	Short Keyword
COMMUNICATION AND SIGNAL PROCESSING	EE1
POWER ENGINEERING	EE2
MICRO ELECTRONICS & MEMs	EE3
INSTRUMENTATION	EE4
OPTICS & PHOTONICS	EE5
INTEGRATED CIRCUITS & SYSTEMS	EE6
CONTROL & OPTIMIZATION	EE7

You should indicate your preferences while applying for the program. If you are unsure about your interests, you could choose multiple research themes without any fear. While the above themes are just indicative of our research work, we usually cross several themes ourselves. So, it may not be uncommon to work on the interface of two research themes.

You first need to write a 1 or 2 hours test that will probe your fundamentals in different themes as per your application. If you are successful in the written test, you will be called to interview with us on the same day. We make our final offers of admission based on both the written test and interview.
