  • Dr Raghunath Anant Mashelkar delivered the 2024 Aston University Annual Distinguished Lecture
  • He has been president of the Indian National Science Academy and director general of the Indian Council of Scientific and Industrial Research and has received multiple honours and awards
  • He was also presented with an honorary professorship in recognition of his outstanding contribution to academia and beyond.


Dr Raghunath Anant Mashelkar delivered Aston University’s 2024 Annual Distinguished Lecture to more than 70 invited guests on 22 April.


One of the world’s renowned figures in polymer science, research leadership and intellectual property rights, Dr Mashelkar, a chemical engineer, is a global leader and inspiration in his native India and the wider international research community.


In recognition of his outstanding contribution to the research community, Dr Mashelkar was bestowed with an honorary professorship at the end of the lecture by Professor Aleks Subic, Vice-Chancellor and Chief Executive of Aston University.


The title of Dr Mashelkar’s lecture was ‘Trapeze Artistry in Biomimetic Smart Gels’. ‘Smart gels’, made from synthetic polymers (types of plastics), can be developed with specific functional properties, such as reacting to changes in temperature and pH. Whilst Director at India’s National Chemical Laboratories, Dr Mashelkar led work which discovered smart gels which can mimic biological functions (biomimetic), including being self-healing, self-organising, and acting as enzymes in chemical and biological processes.


Their properties can be reversibly switched on or off, or they can change volume or shape, through the use of pH or temperature, the ‘trapeze artistry’ of the title, giving them many uses. This included temperature-responsive comfortable insoles for diabetic feet, drilling fluids which can quickly, but reversibly, plug an oil well, and medical devices for the digestive system, which resist the acidic environment of the stomach to deliver drugs, but dissolve harmlessly in the alkaline environment when they leave the stomach.


One of the defining factors of Dr Mashelkar’s work has been serendipity. He told the story of a smart gel that dried to become a completely different shape when dried in his laboratory’s old oven rather than the new oven. One of his research team discovered this was due to the presence of copper ions from corrosion in the oven, which changed the way the molecules arranged themselves and led to a whole new area of research on polymer self-assembly. As he said:


“Eyes do not see what the mind does not know. Look at the 'failed' experiment very carefully, maybe the next big breakthrough is waiting there!”


Dr Mashelkar also spoke on his life story, from a young boy in India, attending the local municipal school, to addressing thousands of the world’s best minds at places like the World Economic Forum and the World Bank. His great passion now is ‘Gandhian Engineering’ based on the principle of more performance, from fewer resources, for more people. He created the Anjani Mashelkar Award, named after his mother, for the best low-cost, high-technology innovations. Winners have included an Internet of Things-based maternal healthcare system for rural areas and a smartphone app to assess lung health.


Dr Mashelkar is proud of his work on Gandhian Engineering. Speaking after the lecture he said:


“Rising inequalities create social disharmony. Now, you can’t make the inequalities vanish because you can’t make poor people rich overnight. What is needed is access. Can we give access equality, despite the income inequality? And that’s the principle of Gandhian Engineering. In my lecture I showed a photograph of a poor lady in a hut with a mobile, and a rich lady from a city who also had a mobile. This is equal access. It was not possible previously when mobiles were so expensive. In India now we have good public infrastructure. Data is now Rs 4 per GB and wireless is free. Once you start giving access, there is a parity.”


Professor Subic said:


“It was a privilege and a pleasure to welcome such a celebrated scientist as Dr Mashelkar to give the Aston University Annual Distinguished Lecture this year. Once again, we have brought a renowned international leader to engage with our community and present some of the most exciting research going on in our world today, while also inspiring the next generation of researchers and international citizens. I am deeply honoured that Dr Mashelkar has accepted an honorary professorship from Aston University in recognition of his international standing and significant contributions to scientific research and innovation.”


The distinguished lecture series was established by Professor Subic in 2023. It brings influential speakers to the University to address major scientific breakthroughs, as well as social, cultural and policy issues. The first distinguished lecture was given by Nobel Laureate Peter Agre in 2023.


Speaking after the lecture, Dr Mashelkar said:


“I am absolutely honoured to get this honorary professorship from Aston University. Aston University is excelling in a number of areas. In terms of its future, I consider that to be very bright for the simple reason that the University’s dynamic Vice-Chancellor is making big changes with speed and skill, with expansion, inclusion and excellence. To be honoured with an honorary professorship is one of the greatest satisfactions and fulfilments of my life.”


The lecture was followed by a drinks reception to allow guests to meet Dr Mashelkar and further discuss his work.


A video recording of the 2024 Annual Distinguished Lecture will be made available on the University website at a later date.

Aston University economists say Prime Minister can reduce UK trade vulnerability with China visit

Greenland episode exposed UK’s lack of effective response to economic coercion from allies Research shows tariff retaliation would have cost the average UK household up to £324 per year Economists say China visit is “portfolio risk management” – diversification reduces vulnerability. The Prime Minister’s visit to China – the first by a British PM since 2018 – is an opportunity to reduce the UK’s vulnerability to economic coercion, according to new research from Aston University. A policy paper from Aston Business School’s Centre for Business Prosperity analyses the January 2026 Greenland tariff episode, when President Trump threatened and then withdrew tariffs on eight European countries. The researchers found that the UK had no good options: retaliation would have made Britain worse off, while absorbing the tariffs left Europe without credible deterrence. Director of the centre for business prosperity, Professor Jun Du, said: “The Greenland episode was a wake-up call. When your principal security ally threatens economic coercion, the old assumptions about who is safe and who is dangerous no longer hold. “The PM’s China visit should be framed as portfolio risk management – building diversified trading relationships that reduce the UK’s exposure to any single partner. Just as investors don’t put all their money in one stock, countries shouldn’t put all their trade into one basket. A UK with multiple strong partnerships is harder to pressure, whether the pressure comes from Washington or Beijing.” The research found that coordinated UK–EU tariff retaliation would have cost British households up to £324 per year – the worst outcome modelled. But the authors argue that Europe has untapped leverage elsewhere: the US runs a €148 billion annual services surplus with the EU, and mutual investment exceeds €5.3 trillion. Associate professor of economics and co-author, Dr Oleksandr Shepotylo, said: “Tariff retaliation fails because it hurts consumers and distorts the economy – the retaliator suffers similarly to the target. But Europe has cards it isn’t playing. Services, investment screening, and regulatory access are pressure points where Europe can respond effectively.” UK exports to China fell by 10.4% in the year to Q2 2025, with goods exports down 23.1% – the sharpest decline among major trading partners. The researchers argue that this closes off the UK’s largest alternative market at precisely the moment US reliability is in question. The paper identifies three priorities for UK policy: Recognise the permanent incentives behind US tariffs. US tariff revenue hit $264 billion in 2025. Trade negotiations alone cannot resolve revenue-driven policy. Build UK–EU coordination on non-tariff instruments. Services, investment, procurement, and regulation offer leverage that tariffs do not. Treat China engagement as portfolio risk management. Concentration in any single market creates vulnerability. Diversification is not about picking sides – it’s about resilience. Professor Du added: “The question for the Prime Minister is whether to use this breathing space to build resilience – or wait for the next Greenland.” To read the policy paper in full, click on this link:

Medication adherence: Why it matters and how we can improve it – public lecture by Professor Ian Maidment

Professor Ian Maidment is a professor in clinical pharmacy at Aston Pharmacy School His inaugural lecture will explain why patients struggle with taking medication and present possible solutions to the problem Professor Maidment is a former practising pharmacist and an expert in medication optimisation and management in mental health and dementia. Professor Ian Maidment, professor in clinical pharmacy at Aston Pharmacy School, will give a public lecture about his life’s work on 5 February 2025. In his inaugural lecture, Professor Maidment will reflect on his journey from a childhood in Kent to becoming a leading researcher in clinical pharmacy. After more than two decades working in the NHS, in community pharmacy, mental health, dementia care, and leadership roles, he joined Aston University in 2012. His research focuses on the real-world challenges of medication optimisation for patients, carers, and healthcare professionals. The title of Professor Maidment’s lecture is ‘Medication adherence: Why it matters and how we can improve it’. Every year, the UK spends nearly £21 billion on medicines. Yet up to half of people with long-term conditions do not take their medication as prescribed—a problem known as non-adherence. This has profound clinical consequences and significant financial implications for the NHS. Professor Maidment will draw on his experience to explore how factors such as medication burden and side-effects influence adherence, the challenges posed by conditions such as dementia and severe mental illness, the role of pharmacy in supporting adherence and why tackling non-adherence requires a system-wide approach. He will also offer practical solutions to one of healthcare’s most persistent problems. Professor Maidment said: “We need to understand why patients struggle to take their medication and then develop and test solutions that work well.” The lecture on Thursday 5 February 2026 will take place at Aston Business School. In-person tickets are available from Eventbrite. The public lecture will begin at 18:00 GMT with refreshments served from 17:30 GMT. It is free of charge and will be followed by a drinks reception. The lecture will also be streamed online.

New research partnership to develop biodegradable gloves from food waste for healthcare sector

Knowledge Transfer Partnership between Aston University and PFE Medical to develop a biodegradable clinical glove from food waste The gloves will provide a low-cost, convenient and sustainable alternative to the 1.4bn disposable gloves used in the NHS each year The innovation will reduce clinical waste and costs and help the NHS reach its net zero goals. Aston University and Midlands-based company PFE Medical are teaming up to create biodegradable gloves made from food waste for use in the NHS. They will offer a low-cost, convenient alternative to disposable gloves without compromising patient safety. More than 1.4bn disposable gloves are used by the NHS each year. They create large volumes of clinical waste which has both an environmental and economic cost. The Knowledge Transfer Partnership (KTP) project will develop a more sustainable alternative made from polymers derived from food waste such as orange peel, able to degrade naturally. The gloves will initially be for use during low-risk tasks such as ultrasound scans, rather than in more critical situations such as operating theatres. The gloves would be designed to not only reduce clinical waste and costs in the NHS, but also carbon emissions, helping the NHS reach its goal to be the world’s first net-zero health service. With most personal protective equipment (PPE) currently sourced from Chinese manufacturers, the goal is to develop a biodegradable glove that can be manufactured using a UK supply chain. The challenging project draws on Aston University’s expertise in sustainable polymer chemistry, centred at Aston Institute for Membrane Excellence (AIME). Aston University has one of the largest research groups of polymer chemists in the UK. The project will be led at the University by Professor Paul Topham, director of AIME, and Dr James Wilson, AIME associate member. The research team have chosen to focus on polymers from food waste in order to ensure that the final product can be manufactured sustainably. Most polymers are currently made from petroleum. Polymers made from food waste, ranging from fruit waste to corn or dairy products, have the potential for antioxidant and antibacterial properties if designed appropriately. The team will manipulate the polymer molecules so that they include the right monomers (the smaller units which make up the molecules) in the right location to achieve the properties they require. Critical to the success of the project will be PFE Medical’s commercial and clinical experience of taking new innovations into medical use. It will be the third KTP between Aston University and PFE, following on from successful projects to develop an automated endoscope cleaner, now in use across University Hospitals Birmingham NHS Foundation Trust (UHB). Professor Topham said: “At Aston University, we have a long history of working with industry, of translating fundamental research into solutions for real world problems. This project with PFE Medical provides us with that route, to take our science and engineering and make a difference to peoples’ lives. That’s exactly where, as researchers, we want to be.” Rob Hartley, CEO of PFE Medical, said: “Our previous KTP with Aston University was a phenomenal success, thanks to the brilliant team we had on board. I’m just as excited by this project, which is looking to solve an equally long-standing problem. If we can achieve our goal, then the implications are huge, going far beyond the NHS to all the other situations where people are wearing disposable gloves.” KTPs, funded by Innovate UK, are collaborations between a business, a university and a highly qualified research associate. The UK-wide programme helps businesses to improve their competitiveness and productivity through the better use of knowledge, technology and skills. Aston University is a sector-leading KTP provider, ranked first for project quality, and joint first for the volume of active projects.
