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.
