Oli Weber (Cohort '13) and Dan Davies (Cohort '14) recently attended the Boston MRS Fall Meeting 2016. This post was jointly written about their experience.

The CSCT was well represented at the Boston MRS Fall Meeting 2016, with myself, Dan Davies, Jemma Rowlandson (previously Cohort ’13, now University of Bristol) and alumnus Dr Adam Jackson (Cohort ’11, now UCL) in attendance. A major international conference can be an overwhelming experience, especially when it spans, conceptually, the whole of materials science and physically, an entire conference venue and the hotel next door. Much of the week was spent dashing between seminar rooms, trying simultaneously to catch the best talks while working off the effects of overlarge food portion sizes.

I embodied an academic stereotype by writing my presentation on the flight on the way to the conference, having being told at the last minute that my poster abstract could be swapped for a talk. I gave my talk on the first day of the conference in symposium ES3: Perovskite Solar Cell Research from Material Properties to Photovoltaic Function. I spent a fair amount of time in the perovskite session, hearing numerous exciting results, though many of my personal conference highlights came from wandering into seminar rooms with tangential or non-existent links to my own research. I heard Shreyas Shah from Bell Labs speak on interfacing nanomaterials with neural stem cells for neural regeneration, by combining visible light-responsive ion channels and upconversion nanoparticles to transform infrared light transmitted through biological tissue into blue luminescence to achieve optogenetic control of neuronal activity.

There were many other great talks, including Yi Cui from Stanford, on thin film silicon photovoltaics, Dan Nocera from Harvard, on complete artificial photosynthetic systems and Yuval Goren on the conservation of clay cuneiform tablets in the Negev desert, which are the oldest written records and provide the only external account of the Trojan war.

Meanwhile, Dan presented a poster in the TC2 symposium on high throughput screening of inorganic materials. The poster sessions at the MRS meetings are always very well attended and quite intense – it can feel like giving a two-hour oral presentation! The work went down pretty well though and it was a great opportunity to discuss it with so many researchers with such a broad variety of interests and backgrounds.

Other than that, Dan spent most of his time in the TC1 and TC2 symposia on computational materials chemistry and materials discovery guided by computation. The work presented in TC2 by curators of the Materials Project, Gerbrand Ceder and Kristin Persson, was particularly interesting as a demonstration of the high-throughput calculations that are now possible with modern supercomputers. On the flip side, the TC1 symposium had some really interesting sessions on machine learning, where it was shown how data-mining and statistical analysis techniques are now being used to predict new materials, thereby avoiding costly quantum mechanical calculations altogether. Anubhav Jain from Lawrence Berkeley National Lab presented some new codes he had developed in order to aid materials scientists who are interested in applying data-mining techniques.

The conference also had some excellent sessions on the ‘Broader Impact’ of materials research. For example, the symposium BI1: Today’s Teaching and Learning in Materials Science – Challenges and Advances, featured some very impressive educational studies on the best approaches for teaching undergraduates and graduates materials science topics. These sessions were ideal for picking up transferable knowledge and tips that could be applied in teaching roles as well as in public engagement activities.


Oli is studying towards his PhD on 'Optimizing energy harvesting processes in metal halide photovoltaics' with Professor Mark Weller and Professor Chris Bowen.

Dan is currently working on his PhD project: 'Interface engineering for indium-free transparent electronics' with Professor Aron Walsh, Dr Duncan Allsopp and Dr Ben Morgan.


Teaching and learning experience at Yonsei University

The following blog is contributed by Dan Davies of the '14 cohort.

At Easter time this year, in order to finally break out of the annual habit of stuffing my face with inadvisably large quantities of chocolate, I travelled to Seoul in Korea where Easter is altogether less of a big deal. I was kept on the straight and narrow as far as this goal was concerned by my supervisor, Aron, and a PDRA from the group, Jonathan, who also came along. As well as this purpose, there was of course other academic motivation for the trip.

Firstly, Aron was giving an intensive 12-lecture series to Masters students on materials for solar energy at Yonsei University and Jonathan and I delivered a lecture and practical workshop each on using the programming language Python as part of this course. I have always had a great deal of respect for lecturers and educators in general, but this respect increased enormously after going through the time-intensive and energy-zapping process of preparing and delivering just one (albeit quite long) lecture and one workshop. It was certainly a really valuable exercise for me from a skills perspective and I was really pleased with how it went. I think this was helped to some extent by how motivated and diligent the students were though- outstanding attitudes to learning all round!

Secondly, a small workshop had been organised by Professor Seungwu Han at Seoul National University (SNU) on Electronic Structure of Materials. This was a fantastic opportunity for the three of us to present some of our work in a fairly relaxed setting. Having said that, it is slightly daunting when the person speaking after you is an associate dean at Korea’s largest public university. SNU is a seriously large university too- with over 200 buildings, if you get the bus there and get off at the wrong stop, you could be in for a trek across the mountain that would put you in mind of the final scenes of the film ‘Touching the Void’.

Lastly, my international supervisor is Professor Aloysius Soon from Yonsei University so I was also able to meet him in person and fill him in on what I’d been up to so far as well as have some exciting discussions about the direction of my project. The only evidence I have for this last meeting is a photo of Aolysius, some of his group members and I, eating some incredible pizza. This is a remarkably unflattering photo, so instead I’ll leave you with a picture of a lovely fountain-mountain combo on the Yonsei University campus.



As well as the above activities, we were able to explore many of the other delights that Seoul had to offer, including an excellent café culture with the best coffee I have ever tasted; some of the most unusual but delicious food I have ever come across; what must be the cheapest, most efficient and easy to use subway system on the planet and truly flabbergasting views of the city from the top of Namsan tower. Seoul, I will be back!
