Workshop on Advanced Topics in Complex Networks

A large amount of the research carried out at Imperial College is highly interdisciplinary in nature. The field of Network science is no exception to this. “Network scientists” study the behaviour of complex interconnected systems which are often represented mathematically by graphs or complex networks. Examples of these systems include: social networks, transportation networks, such as the London Underground, and even the vast network of neurons in our own brains. The disadvantage of working in such a multidisciplinary field is that individuals performing similar research can often become scattered across different departments in the college without any idea that others working on similar issues exist! Imperial College’s Networks Networking group was created as a way of bringing together those working on graph theory, complex networks and related subjects in different departments.

On Wednesday the 23rd of May Imperial College’s Networks Networking group held a workshop entitled Advanced Topics in Complex Networks which was funded and supported by Imperial College Graduate School’s research community fund . The aim of the event was twofold. Firstly, it was an opportunity for PhD students and early career researchers to gain some insight into the “state of the art” mathematical tools being employed by researchers in the area. Secondly, it was to provide a networking opportunity for those in the field. The event was attended by roughly 3040 PhD students and postdoctoral researchers from Imperial College working on a variety of topics. Attendees came from a range of departments including Ecology (Silwood park campus), Physics, Mathematics and even Economics meaning that the event was truly interdisciplinary.

Imperial College’s mathematics department who are both active researchers in the field of graphs and complex networks. Professor Barahona spoke about “highdimensional
data, graph embeddings and multiscale community detection” while Dr Colijn gave a talk entitled “Comparing tree with new metrics and features: applications in evolution and infectious
disease.” Both talks explored ideas that related to the analysis of large graph data sets and also gave insight into how techniques from machine learning are beginning to creep into
network science as well. The talks were followed by a break for lunch which provided an opportunity for the attendees to network with researchers and discuss any questions raised
in more detail.

The first talk of the afternoon was given by Professor Reimer Kühn, a Professor in mathematics at King’s College London. His talk entitled “Spectra of Random Stochastic
Matrices and Relaxation in Complex Networks” gave details of the mathematical machinery which can employed of study graph spectra. This is an important topic in applied network
science where researchers are often interested in dynamical processes unfolding on graphs. These may include: the spread of disease, models of opinion formation or perhaps the
synchronization of stations in power grids. The final talk of the day was from Dr Cornelia Metzig, a postdoctoral researcher at Imperial College who gave a talk concerning her recent
research on dynamic network models. This provided an opportunity to learn about the type of questions that practicing researchers in network science are trying to answer.

In future the Networks Networking group intends to organise more events for the benefit of researchers at Imperial working in network science and graph theory. These meeting will
allow individuals working in the area to keep up to date with the latest research and potentially to foster collaboration.

NHLI Careers Panel

The National Heart and Lung Institute Postgraduate committee organised a PhD careers panel on the 7th June with great success. The event, which was held at the union bar in South Kensington, was extremely well attended. Students travelled from all the Imperial campuses, which is often a challenge to achieve. Our five panellists were all working in non-academic areas such as industry, medical writing and scientific consulting. Students asked questions about interviews, their day to day life at work and why they chose their career paths.

After the panel session, students had the opportunity to chat one on one with the panellists and ask more specific questions. The atmosphere during the Q&A and networking was made even better with drinks and buffet which were provided thanks to the Research Community fund.

The feedback received by the students and those involved was overwhelmingly positive. Students commented on how it was a great chance to learn about career possibilities outside of the university setting.

We as a committee believe that events like these are an essential part of the PhD experience and for career development in the department. We are therefore grateful to the graduate school for providing funding without which nights like these wouldn’t be possible.

St. Mary’s Summer Party

St. Mary’s Campus does not really have a common room where students from different research groups get to know each other. Trying to break down the barrier, there was a Christmas party organised for all students working in the Medical School Building. Based on the huge success and numerous thank yous for organising this party, we decided to put together another party. A summer party this time, with the presence of the British summer drink of choice: Pimm’s with fresh fruit.

Besides Pimm’s, we provided prosecco, two kinds of beer, non-alcoholic bubbles and lots of water thanks to the Graduate School Cohort Building Fund, who sponsored this event. Because of the high temperatures, everything was kept cool with ice and people could enjoyed a cold beer, refreshing prosecco or the very popular Pimm’s. At 5 pm on Tuesday 22nd of May 2018, everything was ready to receive guests in the Committee room on the ground floor of the Medical Building at St. Mary’s Campus. Drinks were cold, some nibbles were on the tables and Bill Nye the Science Guy started explaining science on screen.

Within 5 minutes the first people showed up to start celebrating summer and looking for those people they talked to last time. Several people thanked us for organising even before they got their drinks. By starting at 5 pm, we managed to catch the people with families before they went home and we also got people that work late by having the party still going at 7 pm. People from the School of Public Health, Virology, Respiratory Medicine, Infectious Diseases and Paediatrics all showed up. Master students joined the party as well and could casually ask those questions about PhDs they did not want to ask in the lab.

At 8.30 pm it was time to start cleaning up and everyone that was still hanging around helped out by throwing out trash, collecting glasses and bottles, and cleaning the tables. Within 15 minutes, all signs of a party were gone. I’m already looking forward to the next one!

MetID workshop

By Erika Dorado and Kiana West, STRATiGRAD PhD programme, Department of Surgery and Cancer

A workshop focused on the identification of metabolites was organised by the STRATiGRAD PhD programme in collaboration with the Centre for Metabolomics and Bioanalysis (CEMBIO). The MetID workshop took place between 12th and 15th June 2018, in Madrid.

MetID workshop participants

The MetID workshop started with oral presentations given by PhD students from both Imperial and CEMBIO. The PhD students had the opportunity to present their research projects in seven minutes to an audience composed of recognised researchers in this field. We had the opportunity to practice our presentation skills and share our research experience by providing concise information about our PhD projects. On the second day, the workshop started with an introduction by the director of CEMBIO, Dr. Coral Barbas. During the second and third days we attended lectures given by researchers from CEMBIO about fragmentation rules and mechanisms (Dr. Ana Gradillas), data curation (Dr. Javier Ruperez), as well as theory-practical lectures about annotation on MS and MS/MS level (Dr. Joanna Godzien). In addition, Dr. Joram Posma from Imperial presented two lectures about statistical experimental design, bias and confounding, as well as MetaboNetworks and graph theory.

On the third day, after finishing the lectures, we attended an exhibition on extended reality space offered by the Telefonica foundation from Madrid. We had the opportunity to experience different realities such as augmented, mixed and virtual reality. After this interesting activity, we enjoyed some sightseeing in the centre of Madrid on our way to have dinner together. During these activities the students from both universities had the opportunity to do some valuable networking.

On the final day, we visited the laboratories at CEMBIO. Dr. Antonia Garcia gave us a tour and showed us all the equipment in their laboratories, including liquid chromatography and mass spectrometers. The final day was concluded with a contest about metabolite identification to allow the students to apply all the knowledge acquired during this MetID workshop. Groups composed of students from Imperial and CEMBIO were organised randomly by Dr. Godzien, each group had the great opportunity to apply what we had learned about annotation on MS and MS/MS level by identifying 12 different metabolites. This contest allowed us to apply our communication and team work skills. The group that won the contest was composed of Vincen Wu and Erika Dorado from Imperial and Cecilia Barbas from CEMBIO.

We want to thank the Graduate School for providing generous funding jointly with the STRATiGRAD PhD programme to carry out this workshop. We want to thank Dr. Isabel Garcia (coordinator of the STRATiGRAD PhD programme), all PhD students and researchers from Imperial and CEMBIO for all their effort organising and participating in this workshop. This workshop not only encouraged critical and independent scientific discussion on metabolite identification, but also showed us the importance of networking and scientific collaboration at an international level.

MRC-LMS PhD Workshop & Careers Forum at the Wellcome Collection, Euston Square

The second annual Medical Research Council (MRC) London Institute of Medical Sciences (LMS) PhD Student Retreat took place on Friday 25 May 2018. Held at the iconic Wellcome Collection in Euston Square, this event offered PhD students from all year groups the chance to engage and socialise with students from outside of their immediate research section.

Building on the success of the inaugural 2017 retreat held at Kew Gardens, this year’s event had a renewed focus on ‘Career Development and Networking’; prompting students to start considering what future avenues they may wish to explore upon completion of their PhD studies.

In this vein, the day began with a Networking Workshop delivered by Katie Dallison from the Imperial Careers Service, which provides students with free help and advice regarding career advancement, like CV checks and interview preparation. Katie highlighted the importance of making connections in all types of professional events, and shared tips to reduce pre-networking anxiety. During the workshop, students also had the opportunity to practice and refine their “elevator pitches”, get further ideas of recruitment processes, and recognise uses and downfalls of social media.

The students had the ability to use these newly acquired skills in the PhD student poster presentations, facilitating discussion based on current research that PhD students are carrying out at the LMS. The topics ranged from patient-derived neurons to study Down syndrome, to 3D genome architecture and gene regulation, to the evolution of transposable elements. Particularly outstanding posters were acknowledged by the Poster Awards, where this year, the first place was awarded to Helen Paterson for her poster entitled ‘The role of splicing factors in metabolic health and disease’, followed in close succession by Toni Beltran and Holly Simpson Ragdale, in 2nd and 3rd place respectively.

This also gave time for students to visit the vast collection of medical based artefacts from all over the world, collected at the Wellcome Collection. Especially noteworthy in the collection, is the presence of all volumes of the printed version of the first sequenced human genome.

The unanimous highlight of the day however, was an afternoon careers panel which brought together a unique collection of individuals who have gone on to follow a range of post-PhD career paths. The panellists represented diverse fields, including the biotechnology, pharmaceutical, scientific editing, management consulting and patent law industries. Chaired by our own Social Representative, Matt Newton, the panel discussion allowed the speakers to share with us industry-specific insights, whilst also being open to discuss the factors that helped shape and influence their decisions at key moments of their respective careers.  We would like to send a huge thank you to the following individuals for sharing their time and knowledge with us all!

Following the panel, the students received a talk from the day’s keynote speaker, Professor Steve Jackson, who is currently a senior group leader at The Gurdon Institute (University of Cambridge), and fellow of the Royal Society. His talk entitled “Cellular responses to DNA damage: mechanistic insights and applications in cancer therapy” illuminated how basic molecular understanding of cellular processes can be translated into clinical applications, and how he was able to follow the success journey of a drug from the lab bench to the patients in clinic.

The day culminated with a networking reception, where students had the opportunity to continue discussions with panelists and speakers from throughout the day. All in all the day was a triumph for the LMS Student Committee, who put together this event, and we very much look forward to the 2019 Student Retreat!

Finally we would like to take this opportunity to acknowledge generous funding from both the Imperial College Graduate School and Medical Research Council.

How interventions are spread: Winning second prize at the Research as Art Summer Showcase

By Sophie Spitters, PhD Student, Department of Medicine

The Imperial College London Graduate School organised their annual Summer Showcase on Friday July 13th. The showcase aims to celebrate research undertaken by PhD students at Imperial and invites staff, students and visitors to find out more about their work via a poster and a research as art exhibition. I joined the research as art exhibition, showcasing my NIHR CLAHRC NWL research, and won second prize! First prize was won by Iman Ibrahim, who demonstrated what it takes to get clean drinking water to our taps in her mandala called ‘the ripple effect’. And third prize was won by Laura Braun for her ‘sludge cake’ made from sewage, demonstrating the value of faecal waste treatment in order to return it safely to the environment as a natural fertiliser.

 

How interventions are spread

My art installation, titled ‘How interventions are spread’, aimed to communicate the reality of spreading healthcare improvement interventions, which often does not follow the expected trajectory. Healthcare improvement is often depicted as a linear straightforward process. First, a problem is identified. Then, a potential solution or intervention gets implemented in one area. Finally, if that intervention has shown to be successful, it is spread to other areas. The aim of spread in this context is to replicate the successful intervention exactly as is. Big investments are made to demonstrate that positive outcomes are linked to a particular intervention. So why change a winning formula? Why change an evidence-based intervention?

My research shows how in reality, the process of spread is a lot more complex. Evidence-based interventions often get presented as nicely packaged products with a clear step-by-step manual, not reflecting the messiness of interpersonal relationships, hard work and contextual dependencies underpinning its development. Hence, interventions do not just get picked up in one place and dropped off in another. When spreading to other areas, interventions change and develop depending on local priorities, capabilities and resources. This work is based on the spread of an allergy service improvement initiative.

I tried to communicate these issues through my art installation via two components: the video below and an interactive element encouraging people to build their own intervention with the (flawed) information and materials provided in the black box.

 

Exhibiting at the Summer Showcase

Joining the research as art competition was a great opportunity for me to communicate one of my research findings in a creative way. During the creation of the project, I realised that replicating a simple playdoh sculpture (which I used as a visual analogy) had many subtleties in common with replicating interventions in real-life quality improvement efforts. I never actually expected to see that. The Summer Showcase gave me the chance to explore these similarities and differences further with the visitors. It was great talking to people from different disciplines and different backgrounds about my research and to hear about their thoughts and insights. The art installation proved to be a great vehicle to start discussion, explore connections with people’s own experiences, and to visually demonstrate a key take home message from my research.

“Dream Today, Do Tomorrow”: Reflections from a cross-cultural, climate change-themed summer in Beijing

By Shiladitya Ghosh, 2nd Year PhD Student, Chemical Engineering, Imperial College London

In the modern day, students (especially PhD students) tend to have a crippling fear of committing to future plans because – “what if I end up needing those extra days to finish this report or do repeats for my experiments?” As the 2018 edition of the Imperial – Tsinghua Global Fellows Programme (GFP) on Climate Change and Energy drew near, I too had misgivings. Who was going to write my reports for me?!

However, a change in setting and scenery helps to calm and settle the mind – and I experienced this upon landing in Beijing in the sweltering 36°C early morning sun. Meeting other participants reassured me that we would have an enjoyable and meaningful time one way or another, away from the otherwise-incessant worries of our degrees. In fact, it turns out that several of the Imperial students were still writing their ESA (first year assessment) reports! And I thought I had problems…

When it came down to it, those 5 days completely flew by. As we formed inter-university teams and took part in various tasks, the time spent on learning to effectively communicate while also attempting to work towards common goals took up more and more of our waking moments – even infringing upon mealtimes, as we sought the cooperation of our Tsinghua colleagues in helping us identify the various sumptuous dishes on offer. In return, we also invited our counterparts to join our evening board games crusades, watching the World Cup finals late at night (it came home a little too early…), and even yoga sessions!

Considering that the aims of the programme include facilitating cultural exchange and fostering collaboration, you realise how much of that takes place (and needs to take place) outside of the official programme just as described above. Just like in a professional collaboration, everyone involved will only get the most out of it if they first take the time to understand and connect with the other parties. The actual (technical) work of the collaborative project may only be half the job – the personal connection and groundwork is the other, bigger half!

Without revealing the specifics of the course, I can confirm that there were ample opportunities for mental stimulation whether in finding ways to collaboratively tackle specific issues pertaining to climate change or global energy demands, or through introspection to understand more about themselves, what their personal strengths are and what soft skills they still can develop in. Sure, maybe not every team completed every task, but it was never about that. A line from a poem penned and presented on the final day perhaps sums up both this programme and our own PhD experiences: “It’s about the journey, not the win.”

No single activity felt like a self-contained episode; every session was connected to past and future activities. We learnt about how we function as individuals and how we can best play a role in any team we may work together in. These are very important professional capabilities that I can recommend to any graduate student to consider inculcating in themselves – unsurprisingly perhaps the reason why a GFP course is allowed to fill up the Graduate School course requirements for Imperial students prior to their ESA/LSR/final submission.

Perhaps the most important takeaway from this programme for all of us as individual specialists in our own particular fields was that it opened our eyes and minds to the potential of every discipline to play a significant part in a concerted effort to tackle climate change. My accelerated project team (水星 or shuǐ xīng; Water from the Stars) and cultural exchange team (Imperial Dragons) consisted of members with backgrounds in fluid hydraulics, meteorology, energy storage, membrane technologies, art and systems design, signals monitoring, and cancerology (medicine).

I’d never have expected students in most of those areas to have much of a professional interest in, or even having a way to meaningfully contribute towards, solving the world’s biggest problem lying ahead – but by the end of the week, I had never been happier to have been so wrong in my life.

To everyone reading: thank you for your time reading this. For each person that makes it to this page, that’s one more person that has at least the slightest interest and curiosity about playing a part in tackling climate change. And from what I’ve learnt this summer – no matter what your academic background is, we want and need every single one of you onboard!

Our experience organising SciFun

Inception

A couple of us postgraduate students came together and decided that it will be a great idea to have a mini-conference-type event within the department that could foster learning and networking. There are immensely valuable resources available within the department, with subject matter experts and we thought it would be great to capitalise on that and get these experts to share their experiences in characterisation techniques with the postgraduates.

Event

Since the purpose of the event was to foster learning and networking, it was necessary to have a social event to it as well. Ultimately, we managed to secure 6 speakers to share on characterisation techniques. This was followed by a 5 minute PhD pitch competition opened to all PhD students. We felt that this was a good addition to the event as it allowed students to share their work instead of being a single-faceted event where students were just taking in information. Most of the talks were followed by lively Q&A which fostered learning.
We ended the event with the networking dinner which allowed for more in-depth conversations on topics that was shared during the talks as well as opportunities for further collaborations. More importantly, it was a good chance for people from different groups within the department to gather and get to know each other.

Conclusions

SciFun is a student-initiated event targeted at PhD students which leveraged on the resources within the department. We had a lot of fun planning the event and more importantly, many found the event useful for learning as well as intra-department networking. We are happy that the event was a success and it would not have been possible without the help of our speakers and the attendees. It was our pleasure that we could bring people together for an enjoyable Friday evening of learning and fun.

A Traditional Scottish Affair!

A Traditional Scottish Affair!

ESE PhD’s visit a Scottish Ceilidh Dance for Burns Night

The Graduate Society of the Earth Science & Engineering Department organised a trip to the most famous Ceilidh House in London – Cecil Sharp House – in order to celebrate Burns Night. The evening began with students mingling at Imperial College, giving us the chance to unwind after a hard week at work. We then donned our dancing shoes and headed up to Cecil Sharp House in North London for a wonderful evening filled of traditional Scottish dancing.

For those unfamiliar with Ceilidh dancing, this involves a speaker or “caller” who outlines the dance steps for each dance, some with English roots, some more Irish or Scottish but most involving a fair amount of twirling, promenading and galloping! Many dances involve partners or sets of 4 or 8 – as such it was such a fantastic opportunity for PhD students to get to know each other in a fun and relaxed environment, away from the grind of work. The speaker is accompanied by a live band that usually consists of fiddles, flutes, keyboards and violins but also more old school pieces such as the hurdy-gurdy or the accordion!

Similar to line dancing, which is style of dancing associated with the US, Ceilidh dancing as we know it today originated as literary entertainment and “reeling” dances. It was used as a chance for young couples to meet and court, celebrate events such as weddings and keep people occupied during the long winter nights in Scotland. Steeped in history, and even more relevant being held on Burns Night, Grad Soc was able to sprinkle a little culture and history on the ESE PhD students and a fun (and sweaty!) night was had by all.

The live band and speaker generated an exuberant atmosphere, encouraging everyone to get up and dance regardless of ability. We threw ourselves in with gusto. Not only was it a great chance to get to know each other outside of work but it was a great opportunity for international students to get involved in a traditional aspect of British Culture. All the students who grew up outside of the UK and attended the event said they enjoyed submerging themselves in an aspect of British tradition that was previously unknown to them.

We are extremely grateful for the Graduate School for funding the subsidy of 30 Ceilidh tickets, reducing the price from £17 to £7 per person. As PhD students, it’s so important to get involved in activities outside of work and have the chance to shake off the stress of PhD life whilst also navigating the difficult financial waters that is living in London.
