UCL’s MPA Students Host Second Summit on Sustainability

By leonie.dunn, on 16 May 2024

On 26 April, a cross-faculty student committee representing the MPA degrees from the UCL Institute for Innovation and Public Purpose (IIPP), UCL Department of Science, Technology, Engineering, and Public Policy (STEaPP), and UCL Department of Political Science (DoPS) hosted the second annual Summit on Sustainability.

MPA students The Summit brought together students, academics, and professionals for an interactive and collaborative learning experience as well as engaging discussions about ongoing action in sustainability. This year’s theme, the Power and Politics of Sustainability Transitions, aimed to navigate the increasingly complex world of activism, policy, and conflict surrounding sustainable transitions and solutions.

Collaboration with the UCL Climate Action Unit opened the Summit

Dr. Kris de Meyer from the UCL Climate Action Unit started the event off with a talk about climate change and the uncertainty of the future. He demonstrated how we are doing what we can because it’s what we know, but posed the question: “If we knew the solution, what might we do differently to get there?” The thought-provoking talk set the tone for the event and explored the different realities that can and do exist in sustainability.

Jon Alexander and Jane Davidson in fireside chat about collaboration

Co-founder of The New Citizenship Project and co-author of Citizens, Jon Alexander has worked to center the public at the heart of collaborative issues like climate change and economic insecurity – to treat people like Citizens not Consumers. He sat down with Jane Davidson, former Welsh Government minister and current chair of the Wales Net Zero 2035 Group, to discuss community participation in policymaking. Ms. Davidson delved into her history has a lawmaker in Wales, living through community collaboration for a better future. Her passion for sustainability led to the Wellbeing of Future Generations Act (2015), putting sustainability at the forefront of all government and public organization action.

Panel with Jon Alexander and Jane DavidsonPolicy Pathways Simulation adapted from in-field work for MPA participation

After lunch, the UCL Climate Action Unit once again took the stage to deliver a two-hour activity in which the participating students and staff joined a Climate Strategy Advisory Board to advise on a hypothetical green transition plan set out by the Prime Minister. Policy Pathways was created by the Unit as a virtual exercise for policymakers and politicians to collaborate and deliver different methods of sustainability transitions through financial regulation, taxation, and public subsidies. The simulation was adapted for the Summit with the goal of providing groups with differing perspectives the chance to discuss and debate amongst themselves, leading to somewhat differing strategies.

UCL Climate Action interactive workshopAfter the activity, Dr. de Meyer showed that, in the field, stakeholders struggled to utilise the existing policy tools to deliver effective and affordable green transitions. He brought the conversation back to his opening talk, wherein he stated that we can only do what we know, so we must expand that knowledge in order to expand the reality of sustainability.

Multi-profession panel explores navigating power and politics in the field of sustainability

Moderated by one of the student organizers, the three-person panel discussed different actors’ roles in change, and how power plays into the sustainability movement when it comes to justice and representation. Selina Newell, Director of Climate Action Implementation at C40, Fatou Jeng, founder of Clean Earth Gambia and Youth Climate Advisor to the UN Secretary General, and Asad Rehman, Executive Director of War on Want, unpacked the different levels of action, from individual movements to global affairs. Much of the conversation focused on equity being utmost important for sustainability movements and recognising economic inequality as a major point of conflict when it comes to global change. The cross-sector backgrounds of the panellists offered unique insight into the different powers that activists and policymakers have to enact change through sustainability transitions.

Multi-professional panelClare Farrell speaks on the failure of ‘sustainability’ and where to go from here

To round out the Summit, keynote speaker Clare Farrell, co-founder of Extinction Rebellion, delivered a talk titled Why Sustainability Isn’t Working Out. She spoke on her background in fashion and ethics, and how her work on the ground in activism led to the group’s message of civil rebellion for democratic change. Her thought-proving talk demonstrated the slow-moving and barrier-filled process of change through established political and economic institutions, and how the conventional perception of ‘sustainability’ has failed to come to fruition. Ms. Farrell guided the attendees to think about what must change now in order to achieve future goals in green transitions. She wrapped up the event by evoking hope in action now for change later.

Clare Farrell Extinction Rebellion as speakerAfter closing remarks, guests and attendees were invited to food and drinks for a two-hour networking social with open discussion and further questions.

Continuing cross-MPA collaboration and learning

Last year’s summit paved the way for the collaborative effort made this year. The three departments delivered learning in different contexts. Unifying those views for a cohesive and multi-perspective educational opportunity allowed the attendees and the committee to learn from both each other as well as the guests. Collaboration between the MPAs is imperative as we the students prepare to embark on our professional journeys as decision makers. Our ability to learn from each other must be fostered now so that it is not limited to these formal institutions. After coming together for this year’s Summit, we hope the relationship between the departments’ MPA programs continues to grow and furthers collaboration in the coming years.

Unleashing the economic potential of UK manufacturing

By a.tacu, on 2 May 2024

Image of speaker presentingManufacturing has a pivotal role to play in building a thriving future UK economy which is resilient and can meet many of the increasingly pressing challenges facing UK society.  

But is this fundamental role fully understood by those outside the world of manufacturing? Attending ‘The Future of UK Manufacturing’ event earlier this month has prompted me to reflect on this question.  

Common cross-sectoral challenges and potential solutions 

Recent policy developments such as the UK’s Advanced Manufacturing Plan supported by £4.5 billion of funding for strategic manufacturing sectors, the Net Zero Strategy and the UK Net Zero Research and Innovation Framework point to the increasing awareness of the importance of manufacturing for the UK economy in recent years.  

While this is welcome, a number of challenges continue to hamper the ability of manufacturing to realise its true economic potential. 

One of the key apparent challenges is that, despite the fact that the UK is a global leader in innovation and research, this does not fully translate into economic value through industrial activity [1]. For example, in terms of number of research publications, the UK surpasses the US in per capita terms, but it lags behind in translating scientific knowledge into commercial success. A telling example is that the word ‘manufacturing’ is only mentioned once in the ‘Science and Technology Framework’, which risks creating the perception that the onus is on industry when it comes to scaling up new technologies. 

Although a constant stream of fundamental research is a crucial part of the innovation ecosystem, the ability to scale up lab-based demonstrations needs to become an equally prominent part of how research is undertaken in the UK to set the right conditions for success. Lessons can be learned from the example of the Oxford-AstraZeneca Covid-19 vaccine where the parallel research in immunology and in manufacturing, supported by the Vax-Hub, contributed to the speedy Covid-19 vaccine rollout.  

Another significant challenge for the UK manufacturing community is skills gaps, which amounts to between £7.7 and £8.3 billion in lost annual economic output [2]. Part of the difficulty in attracting talent to manufacturing careers is that manufacturing jobs are still associated with a traditional view of manufacturing roles as being manual and poorly paid. A study led by InterAct suggests that these perceptions can be changed by focusing on levers which have the potential to attract people to manufacturing careers such as flexibility and being part of the solution to many of the health-related, environmental and economic issues we are facing. 

Which leads us to one of the recurring themes that emerged from the discussions held during the event – the importance of storytelling and narrative setting. There was agreement that the UK manufacturing community should challenge outdated perceptions and create a positive narrative about the role of manufacturing that cuts across sectors and is clearly communicated to policymakers and those outside the world of manufacturing. Coalescing around a common strong narrative can support with ensuring manufacturing remains high on the policymakers’ agendas and can attract the skilled people it needs.  

So, what could this narrative be? One of the workshop sessions explored this exact question. A strong narrative should show how manufacturing can be at the forefront of creating good quality jobs and be a fundamental part of the UK’s future economic prosperity and national security.  

Early-stage R&D, which underpins manufacturing innovation, requires continued long-term funding support as businesses are often risk-averse and not incentivised to invest sufficiently at that stage. The Engineering & Physical Sciences Research Council (EPSRC) has been responding to this need through its manufacturing for the future research funding programmes, which is very welcome. I am left convinced that prioritising this type of investment is more important than ever and that, over the long term, these investments will more than pay for themselves in value returned to the UK. 

Context 

The EPSRC together with the High Value Manufacturing Catapult and the Institute for Manufacturing at the University of Cambridge organised ‘The Future of UK Manufacturing’ event in Sheffield. The event brought together academics, policymakers, innovation agencies and industry to review the current UK manufacturing landscape and to look ahead to future research and innovation priorities and opportunities. I attended this event as Policy Adviser for Vax-Hub Sustainable, one of the manufacturing research hubs funded by EPSRC and co-led by UCL Biochemical Engineering and the University of Oxford.

The importance of collaboration to advance digital health

By luis.lacerda, on 27 March 2024

Earlier this month the Government announced a £3billion+ package to update fragmented and outdated IT systems across the NHS and transform the use of data to ease administrative burdens. That same week, the Policy Impact Unit (PIU) hosted a roundtable on digital health in the UK, bringing together colleagues from across UCL (see co-authors) as well as visiting researchers from the FioCruz Oswaldo Cruz Foundation in Brazil.

FioCruz is a federal public research foundation working with academic autonomy under the Ministry of Health of Brazil which was responsible for coordinating the COVID-19 vaccination campaign. The Brazilian delegation were keen to hear about UK experiences on health digitisation, challenges and opportunities, as well as developing a deeper understanding of the context and evaluation of several commitments agreed under the Brazil-UK High-Level Strategic Dialogues from 2020, some of which focussed on health cooperation and were funded by the Official Development Assistance (ODA) [1].

The main challenges discussed in the meeting, in relation to the digitalisation of the NHS, were systems’ interoperability, training and workforce capacity. Although there has been a push towards the adoption of federated data platforms (FDP), which will sit across NHS trusts and integrated care systems allowing them to connect data they already hold in a secure and safe environment, these are still disjointed and connecting them relies on platform providers talking to each other, which often does not happen.

Common challenges: interoperability, training and workforce capacity

The adoption of new digital health approaches is also reliant on having trained healthcare professionals to understand the power of data and new technologies. Particularly in primary care and GPs it is essential to have digitally literate colleagues that can engage communities, be clear and transparent about how health data is used and input it correctly to build FDPs that can be further used for research and to invest on the health of the nation[2]. Programmes like the NHS “Developing healthcare workers’ confidence in artificial intelligence” and inclusive digital healthcare are important, because there is a risk that ambitions to digitise the NHS, which are well intended, could exacerbate existing health inequalities and exclude some groups.

Incidentally, there is still a lack of progress to de-identify General Practice data and address low levels of confidence in new technologies among diverse communities – such as highlighted in the Health and Social Care Committee’s recent evaluation. Trust can be undermined as is the societal buy-in needed to deliver on ambitions for a more digital NHS.

Opportunities and way forward: innovation in regulatory mechanisms

On the flipside, there is an opportunity to bring people in early on to discussions on how AI tools are being used in medical devices, and how to properly manage the balance of risk and benefits such technologies may bring. The recent launch of the UK Regulatory Science and Innovation Networks was discussed, as well as the launch of a MHRA roadmap to create a framework for medical devices in the UK. Patients, researchers and industry representatives being included in this process, and being clear about how data can be used for the purposes of research, poses a great opportunity to bring real impact to clinical practice in terms of diagnosis, treatment, and monitoring of diseases.

Including other global partners in this conversation is essential given the importance of sharing learnings in different contexts, but also given the increasingly important role of international recognition in the medical domain as a factor to evidence impact. Specifically for global issues such as AI and post-market surveillance, where it is very difficult for regulators to know how new tools will perform before they are deployed, there is now a chance to have new standards emerge to shape digital health strategies across countries. We hope that visits like this inspire colleagues to work collaboratively and look forward to hearing from FioCruz how their visit is supporting Brazilian policy decisions on the development of digital health strategies.

What can we do to decrease the cost of advanced cancer therapies and make them available for all?

By luis.lacerda, on 9 February 2024

There are 3 million people living with cancer in the UK, predicted to rise to 4 million by 2030[1]. Different societal groups are affected differently, in particular ethnic minorities who experience poorer outcomes[2]. Health inequalities are complex and their root causes diverse, including the fact that some cancers are more prevalent in specific communities[3]. Advanced research on targeted and personalised treatments can therefore bring hope to improve outcomes in the future and to “close the gap” in the access to cancer care. But how can these be made more affordable and included in holistic government strategies to manage cancer care?

Illustration of two people, two pill bottles and two DNA strandsAt UCL, the Future Targeted Healthcare Manufacturing Hub (FTHM Hub), which brings together academics, manufacturers, and policymakers, has been addressing manufacturing, business, and regulatory challenges to ensure that new targeted biological medicines can be developed quickly and manufactured at a cost affordable to society. This includes innovative research on the manufacture of promising cancer therapies ranging from Chimeric antigen receptor T-cell (CAR-T) therapies through to targeted drug therapies such as antibody-drug conjugates and cancer vaccines. The Hub engages with and supports several clinical groups at UCL that develop advanced therapy medicinal products (ATMPs), some of which have been commercialised or are being translated into the clinic.

The FTHM Hub’s work also includes more fundamental research into optimising manufacturing by innovating processes and finding new ways of reducing production costs of these therapies. Examples of this activity include manufacturing autologous CAR-T therapy at the patient’s bedside or in an automated “GMP-in-a box” system[4], which can bring about benefits in terms of cost reductions, accelerating bench-to-bedside innovation, and mitigate risks that are generated by market shortages[5].

The Hub has worked closely with healthcare specialists and regulatory authorities to analyse how CAR-Ts and other high-cost therapies affect NHS England’s ability to resource other health services. It has conducted detailed supply chain economics analysis to identify key cost of goods drivers for CAR-T therapies, supply chain optimisation, and to assess the risk-reward trade-offs between centralised and distributed manufacture.

The recent agreement reached between the Department of Health and Social Care (DHSC), NHS England and the Association of the British Pharmaceutical Industry (ABPI) on a voluntary scheme for branded medicines pricing, access and growth is a welcomed programme to explore how industry and government can better work to support the delivery of new advanced treatments for cancer, but this is not enough.

Furthermore, and for this important work to continue, investment and support on advanced manufacturing is required to understand possible implementation challenges of novel options such GMP-in-a-box in clinical settings. The new UK’s life sciences manufacturing funding to build resilience for future health emergencies is a good opportunity to do this to expand on the FTHM Hub’s work and ensure every patient living with cancer will have accessibility of treatment irrespective of geographical location.

In addition, time and cost of travel to specialised centres can pose an economic burden to patients and carers due to disparities in cancer care. New centres will also need dedicated staff to help deliver advanced therapies and the FTHM Hub is also training a new generation of professionals to enable rollout of those to patients.

In the week that marks World Cancer Day, the FTHM Hub continues to develop important work to treat patients with cancer and it is our hope at the Policy Impact Unit that we can work towards imagining new futures together, close the care gap, and bring better outcomes for all of those living with cancer.

Adversarial Attacks, Robustness and Generalization in Deep Reinforcement Learning

By Ezgi Korkmaz, on 20 December 2023

Reinforcement learning has achieved substantial progress on successfully completing tasks, from solving complex games to large language models (i.e. GPT-4) including many different fields from medical applications to self-driving vehicles and finance, by learning from raw high-dimensional data with the utilization of deep neural networks as function approximators.

The vulnerabilities of deep reinforcement learning policies against adversarial attacks have been demonstrated in prior studies [1,2,3,4]. However, a recent study takes these vulnerabilities one step further and introduces natural attacks (i.e. natural changes to the environment given that these changes are imperceptible) while providing a contradistinction between adversarial attacks and natural attacks. The instances of such changes include, but are not limited to creating a blur, introduction of compression artifacts, or perspective projection of the state observations at a level that humans cannot perceive the change.

Intriguingly, the results reported demonstrate that these natural attacks are at least equally, and often more imperceptible compared to adversarial attacks, while causing larger drop in policy performance. While these results carry significant concerns regarding artificial intelligence safety [5,6,7], they further raise questions on the model’s security. Note that the prior studies on adversarial attacks on deep reinforcement learning rely on the strong adversary assumption, in which the adversary has access to the policy’s perception system, training details of the policy (e.g. algorithm, neural network architecture, training dataset), and the ability to alter observations in real time with simultaneous modifications to the observation system of the policy with computationally demanding adversarial formulations. Thus, the fact that natural attacks described in [8] are black-box adversarial attacks, i.e. the adversary does not have access to the training details of the policy and the policy’s perception system to compute the adversarial perturbations, raises further questions on machine learning safety and responsible artificial intelligence.

Furthermore, the second part of the paper investigates the robustness of adversarially trained deep reinforcement learning policies (i.e. robust reinforcement learning) under natural attacks, and demonstrates that vanilla trained deep reinforcement learning policies are more robust than adversarially trained policies. While these results reveal further security concerns regarding the robust reinforcement learning algorithms, they further demonstrate that adversarially trained deep reinforcement learning policies cannot generalize at the same level as straightforward vanilla trained deep reinforcement learning algorithms.

This study overall, while providing a contradistinction between adversarial attacks and natural black-box attacks, further reveals the connection between generalization in reinforcement learning and the adversarial perspective.
