Joaquín Faneca submits his thesis!

Joaquin Faneca

Congratulations to final year PGR Joaquín Faneca, who has just submitted his thesis: “Tunable Silicon integrated
photonics based on functional materials”.

Here is Joaquín’s experience of his time with the CDT:

When I started the PhD coming from another country, everything was difficult, you do not have your own language, your family, your friends, your culture, etc. You start from zero and even more, you are doing a PhD. The CDT in Metamaterials was helping us a lot, they were always willing to help us and support us if we need something since the beginning, they were like our family here to be honest. The cohort idea is good because at the end of the day you have different students to share different feelings and I think that is important.

Regarding research it was hard, the first year and half you realise how much you need to work just to get to the level that experts are, you start realising that everything takes a lot of effort and time. After one year a half I think is when you start to have the background in order to progress and start building your own ideas. From that point everything is a lot of work but enthusiastic because you feel that you are progressing. I will say that research is not easy but if you are passionate about it is the best! What an adventure! 4 years in another country, travelling around the world, to Russia, San Francisco, San Diego, there is people that will never visit this place and we were lucky that CDT was paying for our conferences and living costs in these cities. You are in contact with experts in your field, learning from everyone, not only research, but also, leadership, presentation skills, etc. I think this four years have been really intense but now CDT in metamaterials has made us really good professionals.

My future is in reconfigurable integrated circuits using different functional materials, I will keep working with the University of Exeter and the University of Southampton, but from Barcelona, we have different projects going on and I am quite enthusiastic about them.
