 I came from Russia. I did my undergraduate degree in economics last year in high school of economics in Moscow. I chose DC because I considered it to be one of the best European universities in my fields of interest, which are industrial civilization and economic theory. I came here because I've heard about the research center, which is high quality here, and that's really what I wanted to do. First I would say that it's probably one of the hardest master to do in TSE, but really it's not to be scared of because I would say any motivated student should be able to do it. And I would say the strength is that you really get to understand how mathematical tools are used in economics and how to master those tools. I would add to that that this is mathematics is a great stepping stone for people who want to do research, but it's also very useful for people who want to maybe transition to applied mathematics or to big data or maybe even AI. After finishing my master's, I plan to pursue a PhD degree and do research mainly in economic theory and industrial organization. For both of these fields, I think mathematical and economic maturity are very important. I agree. I'm currently in M2 research here and it's actually much easier for me than for other students. To describe TSE forward, exciting, challenging, unexpected, fun.
