Congratulations to David Osuna Ruiz, who has submitted the final version of his thesis, ‘Magnetisation dynamics and tuneable GHz properties of unsaturated magnetic nanostructures’ after corrections.
David looks back on his experience of studying for a PhD as part of the CDT:
Four years ago, I decided to move to the UK to pursue a big goal, professionally and personally speaking, that was to work towards the completion of a PhD in Physics. It just feels like yesterday, although four full years have passed by already since I arrived in Exeter. I am very thankful to myself for having taken such a decision back in January of 2016 and, of course, I am even more thankful to the University of Exeter, the CDT in Metamaterials and my supervisors Feodor Ogrin and Alastair Hibbins for giving me such an opportunity. During these years as a PhD student and researcher, I had so many exciting experiences in the UK, and in many other places worldwide, from Russia to the US. I met so many interesting and good people in the UK and from all over the world, some of them with whom I have been fortunate to have become friends.
After these 4 years, I can say for sure that this has been an unexpectedly enriching and life-changing period of
my life. Aside of doing research, I went on industry placements, visited other colleague researchers, did outreach science, attended many courses and international conferences all over the world and many more things. However, what really makes the difference is the people you meet and those you feel by your side, especially during (the many) hard times while working on the thesis and when things seem to have no way out! In that sense, I feel so lucky of having met and worked with so many kind people during these years.
I very well know that I will hardly forget all the good moments I had during these last four years. I do believe that this whole experience has made me stronger and more prepared for future challenges so, to anyone still working on the thesis, two things: be resilient and most importantly, enjoy the journey! In the end, all of it is valuable and it is absolutely worth the effort.
David is staying on at University of Exeter, as a post-doc. We wish him all the best for his future.
David has co-authored the following publications:
