I chose King's because after my master's I got involved in plasmonics and the use of them in information technologies - I found out that here at King's there is a strong group working on it and I decided to join them.
The best thing of studying in King's is that it is situated in the center of London and you have plenty of activities to do, usually you have to measure yourself because if you do all the things there are in theory you won't have time for studying or for sleeping! Also joining a student hall is better than looking for private accommodation, because you have the opportunity to meet other people and participate in even more activities which can also include travels to places outside London.
For my research I was funded by a King's Studentship (King's Overseas Research Studentship) which has helping me a lot during my stay here in London providing me with a stipend for my expenses. After my PhD I would like to join industry as a researcher or start a company in my home country for developing what I have learned here at King's. If you are thinking of coming to here, either as a undergraduate, master's or PhD student, I'm sure you will meet a lot of people and you will do plenty of activities to get the most out of your study program.
