Zahid Hussain passes his viva!

Zahid Hussain

Congratulations to PGR Zahid Hussain, who has passed his viva. His thesis was titled ‘Metal-organic Framework (MOFs) Derived Nanocomposites: Synthesis and Applications in Photocatalysis’. During his time with the CDT, Zahid published 11 papers, plus an English-to-Urdu translation of Seven Brief Lessons on Physics by Carlo Rovelli. Zahid now works as a postdoctoral researcher at Technical University of Munich (TUM).

Zahid reflects on his experience of undertaking a PhD as part of the CDT:

I believe that life is a journey from nowhere to nowhere. The pleasure of living is in the process itself, and destinations only milestones leading us to the next journey. On this path, we meet all kinds of people. While some settle down on the way, others continue to live nomadic academic lives. As a foreign student, I identify myself with migratory birds, who leave behind many relationships, friendships, cultural and sensory experiences of material and non-material things, seeking better learning and living conditions. In the quest for knowledge and professional opportunities, the continuous struggle to assimilate into a new environment provides us with great learning opportunities, which broaden our mental horizons and deepen the understanding of life indeed.

The last 4 years of my life at the University of Exeter have been full of happenings, professionally and personally. I met some wonderful people, on-campus and off-campus. Many interactions turned into enduring friendships. First of all, I got a great sense of freedom in working with my PhD supervisors Dr Yongde Xia and Prof Yanqiu Zhu, which helped me to grow as an independent researcher. Also, my supportive colleagues and friendly environment of Functional Materials Laboratory (Lab 08) made the overall PhD experience very joyful and productive.

The doctoral training program (CDT) gave me the confidence to think independently and make my own research decisions. During this time, I developed some fruitful collaborations, especially with Dr Asif Tahir (Penryn campus), Prof. Roland Fischer (TU Munich), Prof. Freek Kapteijn (TU Delft, NL) and Prof. Ovidiu Ersen (University of Strasbourg, France). The work I did in these collaborations, greatly contributed to shaping my PhD project.

Along with the PhD, the last 4 years have been the most important time of my life. I married my partner Anna-Maria and became a parent of our lovely daughter Selma as if a sailboat navigating without a compass saw the shore and anchored. Countless moments of joy, peace and contentment, as well as many sleepless nights of childcare, frustrating days, lockdown months of Covid-19 and moving back and forth from Exeter to Munich, all made this time substantial.

We wish Zahid the best of luck with his future.

Ned Taylor passes his viva!

Ned Taylor

Congratulations to CDT student Ned Taylor, who has just finished his PhD. His thesis was titled ‘Ab Initio Exploration of Interface Structures and Their Properties’.

Ned published five papers during his time as part of the CDT and presented at national and international conferences. He was also involved with the Metabuddies scheme- an outreach scheme led by our PGRs, who visit local schools to engage their students in physics and engineering.

Ned looks back on the experience of undertaking his PhD:

It is finally over. I have written my thesis, had my viva, completed my corrections and have been awarded my doctorate. Yesterday I had a final trek up to the Uni as a PhD student to pick up a copy of my thesis that I had printed for prosperity. It is weird to think that it is all over now; below are some of thoughts on my time as a postgraduate researcher.

A PhD is a unique experience for everyone. For me, it was a wonderful time and, although sometimes stressful, it was always worth it. I have relished in the opportunity to conduct research and the freedom to choose my path of study. I have learnt more about the materials that surround us than I had ever expected. The work was demanding, but that was never an issue as the topics were always fascinating. It was amazing going to conferences and have people attend talks to listen to the research that I conducted. Writing scientific papers was often rather tedious, but the outcome was definitely worth it and really helped in the process of writing my thesis.

I have learnt a lot throughout my PhD. In addition to the science, the courses offered by the CDT were, overall, very rewarding and useful. I learnt how to present, how to understand and communicate with others in a team, how to manage projects, how to put myself forward and highlight my skills. I feel that these skills will be vital for progressing beyond the PhD.

The community of PhD students in the CDT offered the chance to forge good friendships. Going on this journey with other PhD students helped me to relax and enjoy the experience. I am also extremely grateful for the support and guidance that my supervisors, Steve Hepplestone and Eros Mariani, have given me throughout the past four years.

As became a theme in the Hepplestone research group near the end of my PhD (before multiple lockdowns, that is), I shall summarise this chapter of my life with a haiku:

DFT was fun
Lots of time spent fighting tech
PhD is done

With my PhD complete, I am now transitioning over into the field of computer science. I have just started a postdoctoral research fellow position at University of Exeter, looking at ways of automating transport models for use in reducing the carbon impact of traffic systems.

We wish Ned all the best with his new role.

Below is a list of Ned’s publications, and conferences he has presented at:

Harry Penketh submits his thesis!

Congratulation to PGR Harry Penketh, who recently submitted his thesis titled ‘“Control of white light emission for illumination and imaging”.

Harry discusses his project in more detail, and offers his advice for students at the start of their PhD journey:

“I have submitted my thesis, although perhaps submitted to my thesis would be a more accurate statement.

To shed some light on my delightfully vague thesis title: this project was sponsored by Dyson and therefore large sections of the research conducted remain protected by a non-disclosure agreement. Working around NDAs aside, I appreciate the broader perspective and additional development opportunities this close industry collaboration has produced.

As is no doubt the case with any job (yes, I’m going to call it a job), doing a PhD comes with its own unique rewards and challenges. In a cohort-based PhD programme one hears a good deal of the latter, but less often in my experience do we reflect on the many great perks that come with the job. I feel privileged to have been able to work with my excellent supervisors Jacopo and Bill and to have had those days (usually in a lab with a new toy) where it didn’t feel like work at all.

My honest and possibly controversial advice for (some) new students: don’t work too hard. How many problems will you solve by spending an extra 6 hours staring desperately at a screen that would have just clicked into place with a refreshed set of eyes and a cup of tea? Look after yourself and don’t forget to find enjoyment in the PhD process.

I’m currently enjoying a break from conventional work and getting stuck into some long overdue property renovation. I hope to remain in Exeter in the medium-term at least.

Harry was involved with various outreach activities during his time with the CDT, including co-organising the mini conference Exeter-Bath Knowledge Transfer in October 2019 with fellow CDT PGRs Iago Rodriguez Diez and Ben Hogan, and students from the Centre for Photonics and Photonic Materials (CPPM) at University of Bath.

David Osuna Ruiz submits his thesis!

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.

Julia De Pineda passes her viva!

Julia De Pineda Gutiérrez with her thesis

Congratulations to Julia De Pineda, who passed her viva this month. Her thesis was entitled ‘Multi-layer metasurfaces for manipulating the propagation of microwaves along surfaces and edges’. Julia published four papers during her time with the CDT.

Below, Julia describes the challenges and rewards of undertaking a PhD and the experience of having a virtual viva:

My years as a PhD student have been an emotional rollercoaster. There have been some very tough times, when I’ve been very close to quitting but there have also been really fun times. And it is the difficult times that make you grow anyway so in the end, I am very happy I decided to stay and finish this project. I also feel very lucky to have been able to work with my supervisors who have always been there to point me in the right direction, even when I thought my research was not getting anywhere. I would also like to highlight the role of the CDT regarding the soft skills training that we received along the way. I feel that sometimes as student we don’t see the importance it has but now that I am starting to look for a job I realise how many transferable skills I have acquired during these four years.

From my time as a PhD student I take some really good friends with me and many great experiences, specially from all the conferences I’ve got to attend and the amazing places I was able to discover in the meantime. However, I am very pleased that this time is over and I am very much looking forward to an exciting new adventure, whatever that is. In any case, I am sure I will take with me everything I have learnt these years, both personally and professionally. I can definitely say that I am a better version of myself than I was four years ago and to me that’s the greatest achievement.

Finally, I would like to say that submitting my thesis in the middle of a global pandemic and therefore having a virtual viva was something I was not ready for and could never have imagined when I started my PhD. But it was alright in the end and an enriching experience after all. So I would like to tell anyone in a similar situation to relax and try to get the most out of the experience. I am sure in the future we will look at it in a different way and realise that it made us learn and grow.

Julia is considering retraining as an air-traffic controller. We wish her the best of luck in her future endeavours.

Pablo Martinez Pancorbo submits his thesis!

Congratulations to PGR Pablo Martinez Pancorbo, who submitted his thesis this month and on 18th September, successfully passed his viva.

Here’s Pablo’s words on the challenges and rewards of undertaking his PhD and his time with the CDT:

My thesis is submitted just in time!

It has been four years working on this incredible research with so many complications and unknowns. But there is light at the end of the road. Neither cancer nor the coronavirus pandemic has stopped me from getting my thesis ready.

During these beautiful years, I have grown and matured beyond what I thought I could. I had memorable experiences and met wonderful people, along with obtaining exciting results and shared them in international conferences around the world. Some of my colleagues on this journey are now my closest friends. I have worked in a broad range of disciplines and regularly collaborated with physicists, chemists, engineers and biologists. I had the opportunity to be a teaching assistant in many modules which included mathematics, physics, fluids engineering and computer science, which lead me to get a teaching fellowship. Moreover, I helped to organised many events for early career scientists over the years, received serval prizes and participated in the QUEX HealthTech Hackathon. However, bad things happened too such as multiple failed experiments during my first six months, getting stuck at the airport in the Rochester (NY) during a research visit due to adverse meteorological conditions and misappropriation of the ownership of my successful grant proposal from the OSA.

I see my PhD as a time of personal growth and independent critical thinking. Thanks to the soft skills I developed in various pieces of training during this time, I managed to receive several small grants and I was awarded the JSPS postdoctoral fellowship at the University of Tokyo, which (if the coronavirus travel restrictions allow) will be my next step in my research journey. I am excited and confident about implementing all I learnt in future career stages.

We congratulate Pablo on his postdoctoral fellowship and wish him the best of luck for his future.

Pablo’s achievements include:

  • March 2019, 1st Prize in #RSCChemBio (Chemical and Biology Interface) at RSC Twitter Poster Competition by Royal Society of Chemistry
  • March 2018, 2018 IOM3 Young Persons’ Lecture Competition South West of England and South of Wales Winner Award by The Institute of Materials, Minerals and Mining (IOM3)

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.

William Ferguson submits his thesis!

William Ferguson with his thesis

Congratulations to William Ferguson, the first of our 2016 cohort to submit their thesis. His thesis was titled ‘Auxetic power amplification mechanisms for low frequency vibration energy harvesting’. William was supervised by Prof. Meiling Zhu, Prof. Ken Evans and Prof. Christopher Smith.

William has published two papers- ‘Student Perspectives On The Concurrent Engineering Challenge 2017’ in Proceedings of the 2nd Symposium on Space Educational Activities; ‘Auxetic Structure for Increased Power Output of Strain Vibration Energy Harvester’ in Sensors & Actuators A. Physical.

During his time in the CDT William has been involved in outreach initiatives such as being a support volunteer for Soapbox Science and demonstrating magnetism to the public as part of Lighting Up Ramm.

In his own words, William describes his experience as a PhD student:

My thesis is done!
Years of swearing at machines, months of banging my head against a keyboard, weeks of procrastinating editing, days of fiddling with MATLAB until the graphs are presentable; all of it came down to collecting the bound theses less than an hour before the printshop closes for who knows how long. So that was fun.
I’ve learnt a lot in the last three and a half years. Such as how to effectively manage people. Perseverance. Systematic problem solving. And thyself. Peaking behind the academic curtain was all very fine and pleasant, but now I’d like to see how the rest of the world compares.
Incidentally, do look me up if you or someone you know is in need of a holistic engineer (a job title I’m trying to give traction, defined as: one who builds/designs with an appreciation of the interconnectedness of all things, often because they’ve been wrapped in gaffer tape by said engineer).

All the best,
William Ferguson

Joseph Beadle submits his thesis!

Joseph Beadle with his thesis

Congratulations to CDT PGR Joseph Beadle, who submitted his thesis last week.

Joseph was supervised by Prof. J. R. Sambles and Prof. A.P. Hibbins, and his PhD project was entitled: ‘An exploration of acoustic metasurfaces’. The aim was to experimentally explore the effect that structuring surfaces had on the near-field acoustic surface waves. The project involved both airborne and underwater acoustics. He published two papers whilst at Exeter: ‘The acoustic phase resonances and surface waves supported by a compound rigid grating’ & ‘Broadband, slow sound on a glide-symmetric meander-channel surface’.

During this time he presented at international conferences such as: ASP DFD (American physics society – division of fluid dynamics) in Denver, USA (2017), and  Underwater Acoustics Conference and Exhibition, Hersonissou, Greece (2019). Joseph has been working as a member of TEAM-A based in QinetiQ, where he is expanding on his PhD work and investigating novel underwater metamaterials for the absorption and manipulation of acoustic energy.
