April 10, 2025 Simmering science for membrane protein production
Episode 5 – Simmering Science: Engineering Bacteria for Membrane Protein Production
In this episode of What is a Membrane?, host Dr Matt Derry sits down with Dr Doug Browning to explore how harmless strains of E. coli are being genetically engineered to supercharge membrane protein production.
Membrane proteins play a vital role in biology and are the targets of top-selling medicines and major vaccines — from COVID-19 to hepatitis B. But producing them in large amounts has always been a scientific challenge, thanks to stress responses that shut down the process in bacteria.
Dr Browning shares how his team is redesigning E. coli to better handle these stresses, using a clever analogy: cooking rice in a rice cooker rather than on a stove. The goal? A smart system that avoids the biological equivalent of a boil-over.
This work is part of a £1.8m project funded by UKRI’s Engineering Biology Mission Award, in collaboration with the University of Warwick and Aston Institute for Membrane Excellence (AIME).
Tune in to learn how this innovative research could pave the way for next-generation drug development and vaccine creation.

September 24, 2024 Making safer, greener device batteries
Dr Matt Derry, a polymer chemist and founding member of Aston Institute for Membrane Excellence (AIME), has spoken to AIME co-director Professor Roslyn Bill about his groundbreaking battery research in the latest episode of What is a membrane?
His research aims to make batteries safer, greener and more recyclable, with the potential to impact portable electronics like mobile phones, electric vehicles and energy storage systems worldwide.
Dr Derry was recently awarded a prestigious New Investigator Award from the Engineering and Physical Sciences Research Council (EPSRC) for his pioneering work on polymer gel electrolytes for batteries. The electrolyte in a battery carries the charge, and is generally a highly flammable, organic liquid. There have been several high-profile incidents involving battery fires.
The £450,000 EPSRC funding will support Dr Derry’s research project, which seeks to replace the flammable, organic liquid electrolytes with safer, more stable gel alternatives. His research group has recently published in this area in the Royal Society of Chemistry’s flagship journal, Chemical Science [https://doi.org/10.1039/D3SC06717C].

May 16, 2024 Explaining novel membrane separation through the medium of chocolate boxes
In the latest Aston Institute for Membrane Excellence (AIME) podcast, three researchers discuss the international BIOmimetic selective extraction MEMbranes (BIOMEM) project and how it will feed into AIME’s work.
BIOMEM will develop a bioinspired membrane technology to selectively extract compounds from water, using 50-75% less energy than current state-of-the-art nanofiltration technologies. The membranes will work at low pressures and at low concentration of the target molecule.
Podcast host Dr Matt Derry was joined by fellow AIME researcher Dr Alan Goddard and Dr Mona Semsarilar from the French National Centre for Scientific Research (Centre national de la recherche scientifique (CNRS)).
The BIOMEM project, which involves collaborators from across Europe, is being led by Dr Torsten Bak from Danish company Aquaporin, with Dr Goddard the research lead at Aston University.
Dr Goddard explained:
“You might want to work on a biotechnology process where you've made a high value chemical that you want to extract from a complex mix, and at the moment you might have to concentrate your solution up, and you might have to do six or seven filtration steps. We want a filter that does it in a single step using a biological transporter.
“And if you can do that in a single step in a platform technology, you'll make all these brilliant biotech processes more commercialisable, reduce your reliance on petrochemicals, and to maybe oversell what we can do, save the planet.”
Dr Derry likened it to a quick way to find your favourite chocolate in a box at Christmas. Rather than scrabbling through, taking out one type at a time until you find your favourite, the process can immediately separate it out with minimal effort.
Aquaporin has developed a membrane that can selectively transport only water molecules to quickly purify water, which is already in use across the world, and even out of this world, for space missions. Dr Bak and the team will bring their membrane expertise to the project.
The team at CNRS, led by polymer scientist Dr Semsarilar, is working on a number of projects for BIOMEM, including developing a type of crystalline material called trianglamine, which they can modify through chemical processes to be hydrophobic or hydrophilic to make things like water channels or adsorption sites, which can be embedded in polymer network for purification processes.
Other researchers at AIME, including Dr Derry and Professor Paul Topham, will work on the ‘glue’ to stick the biological elements of the membranes to the non-biological polymer matrix. BIOMEM will also benefit from the input of partners across Europe including dsm-firmenich, University of Copenhagen and Tampere University.
The podcast was recorded just after the project kick-off meeting with all the project partners, which was held at Aston University in May 2024.
This project has received funding from the European Union’s Horizon Europe research and innovation programme under grant agreement 1011246765, with co-funding for Aston University from UK Research and Innovation (UKRI) under grant agreement No 10112970.

May 15, 2024 Brains, dishwashers and dementia
• Professor Roslyn Bill discusses her research into brain cell membranes with Dr Matt Derry
• Serious brain injuries and dementia are affected by the flow of water through a protein called aquaporin-4 in brain cell membranes
• Aquaporins are responsible for clearing the build-up of waste products in brain cells in a process Professor Bill likens to a ‘dishwasher for your brain’.
Professor Roslyn Bill, co-founder of Aston Institute for Membrane Excellence (AIME), joins Dr Matt Derry to discuss her research into brain cell membranes in the latest Aston Originals podcast.
Water moves in and out of brain cells through tiny protein channels in the cell membrane called aquaporins. One in particular, aquaporin-4, is the focus of Professor Bill’s research.
In 2020, she was lead author on a paper published in prestigious journal Cell on how the channels open and close and how this can be controlled. Uncontrolled water entry into brain cells can occur after head trauma, causing swelling which leads to severe brain injuries of the type suffered by racing driver Michael Schumacher after a skiing accident. Finding drugs to control this water movement could lead to treatments to prevent brain swelling in the first place.
This research into brain swelling and the contribution of aquaporins led Professor Bill to research into Alzheimer’s, a common form of dementia, which is also related to the action of aquaporins. Alzheimer’s is caused by a build-up of waste products in brain cells. In a process Professor Bill likened to a ‘dishwasher for your brain’, aquaporins are responsible for clearing this waste as we sleep.
Professor Bill was selected for an Advanced Grant by the European Research Council (ERC) in 2023, which is being funded by UK Research and Innovation (UKRI). The funded project will further investigate the process, and whether it might be possible to develop a drug to boost the ‘brain dishwasher’, which could be taken to slow or even prevent cognitive decline due to ageing.
Bringing together this biological research with the polymer research of AIME, chemists like Dr Derry will help in the drug development and could also lead to totally different applications.
Professor Bill said in the podcast to Dr Derry:
“We can take the knowledge that we have of how these proteins work in cells and try and apply them to interesting applications in biotechnology. And this is where the sort of work that you (Dr Derry) do comes in, where you can develop plastic membranes, polymer membranes, and then take learning from the biology and try and make really, really good ways of purifying water, for example.”

May 15, 2024 New research institute for Aston University
Founders of Aston University’s newest research institute introduce themselves and their membrane research in new podcast
• Professor Roslyn Bill, Professor Paul Topham, Dr Matt Derry and Dr Alan Goddard founded Aston Institute of Membrane Excellence (AIME)
• AIME will develop biomimetic polymer membranes for applications such as water purification and drug development
• The researchers discussed the aim of the institute, their research and recruitment plans.
The founding members of Aston University’s newest research institute have recorded a new podcast to introduce themselves, their research and the plans for Aston Institute of Membrane Excellence (AIME).
In the latest episode of Aston Originals, Professor Roslyn Bill and Professor Paul Topham, AIME’s co-directors, joined Dr Matt Derry and Dr Alan Goddard to explain how the interdisciplinary team formed and how they will work together. AIME has been set up with the aid of a £10m grant from Research England.
In the podcast, Professor Bill explains that while there are research groups working on polymer membranes, and groups working on biological membranes, AIME will be the first group to bring together the whole spectrum of membrane research and achieve results that would not otherwise be possible.
AIME expects to benefit from its location on the Aston University campus at the heart of what is becoming Birmingham Innovation Quarter (B-IQ). B-IQ is expected to attract small and medium enterprises doing high-tech, cutting edge work, and AIME will be able to plug into that network.
The institute will recruit 20 new members of staff, including lecturers, professors, postdocs and a lab manager, and the team will also offer PhD positions.
Dr Goddard said:
“I think we're really lucky at Aston University that we've got one single big building that houses all of our different schools. We can literally walk down the corridor and find people to collaborate with on different projects. I think we identified real world problems that we can solve together that we can't solve independently.”
The new laboratories will further aid collaboration. Professor Topham said:

“Along with this external grant, Aston University has agreed to support this with £3m. We're building a brand new set of labs. The idea is that we have the chemistry lab on one side, making the materials, all the way on the other side we've got the biological people doing all the clever biology stuff, and then in the middle we've got the analytical suite, where we actually characterise or identify what our materials are and how they perform.
“By having this shared area, particularly in the middle of shared equipment, all the researchers will naturally integrate because they'll be chatting to each other on a daily basis.”
AIME will formally launch on 1 August 2024 and there will be a launch event on 13 September 2024.
