You’ve recently started your own group, what are the big research question/s your group will be focussing on?

One of the central research questions guiding my new group is: Can we design polymeric materials in a way that mimics nature’s ability to eliminate waste entirely? I’m deeply interested in demonstrating that human systems—particularly those built on synthetic polymers—can achieve true sustainability by embracing circularity. Nature offers a powerful blueprint: everything is reused, repurposed, and regenerated in closed loops. In contrast, many of our synthetic systems rely on linear lifecycles that generate persistent waste.
Our approach to this grand challenge is grounded in polymer chemistry. We focus on developing materials and processes that enable complete circularity—whether through chemical recycling, dynamic covalent networks, bio-based monomers, or systems that degrade predictably under specific conditions. The overarching goal is to prove, through both fundamental and applied work, that it is possible to make polymers that support human needs without compromising planetary health.

What inspired you to get into science?

I’ve always been a curious person, and that curiosity naturally drew me to science. In middle school, I joined a few science clubs where I discovered how much I enjoyed doing experiments and understanding why things happened the way they did. That hands-on experience made science feel both exciting and accessible. In high school, my chemistry teacher recognized that I wasn’t just curious—I was also dedicated and organized. She encouraged me to pursue chemistry, seeing potential in me that I hadn’t fully realized yet. Her support and belief in me played a pivotal role in my decision to become a chemist, and it’s a path I’ve thoroughly enjoyed ever since.

What advice would you give to those who are seeking their first group leader position?

I want to start by acknowledging that everyone’s path is different, and advice that works for one person may not apply to another. That said, one piece of guidance I feel strongly about is: be truthful to yourself. Know what truly excites and motivates you, and try to build your path in that direction. Don’t shape your goals or take on roles just because they seem like the “right” steps toward a group leader position—especially if they don’t align with your interests or values. The energy and authenticity you bring to your work are incredibly important, and they’re only sustainable if you’re doing something you genuinely care about.

Meet Jennifer Garden: New Principal Investigator

We are delighted to introduce the next contribution to our New Principal Investigators collection.

Simple divalent metal salts as robust and efficient initiators for the ring-opening polymerisation of rac-lactide

Phoebe A. Lowy and Jennifer A. Garden

Graphical abstract: Simple divalent metal salts as robust and efficient initiators for the ring-opening polymerisation of rac-lactide

Poly(lactic acid) (PLA) is emerging as a leading sustainable polymer due to its bio-derived and biodegradable nature. The demand for PLA based products is rapidly increasing, which has prompted significant advancements into new catalyst design. Many recent developments focus on low-toxicity metals supported by a tailor-made ligand scaffold. In this study, we demonstrate that zinc benzoxide, a simple salt without a supporting ligand, delivers excellent catalytic activity under specific conditions. Notably, this includes industrially relevant conditions, including high monomer loadings, bulk polymerisation conditions, and polymerisation of technical-grade lactide in the presence of air.

Meet the Principal Investigator

Jennifer A. Garden received her MSci (1st Class, Hons, 2010) and her PhD from the University of Strathclyde, the latter under the supervision of Prof. Robert Mulvey. This was followed by 2 years as a postdoctoral researcher in the group of Prof. Charlotte Williams at Imperial College London. In 2016, Jenni moved to the University of Edinburgh as the first recipient of the Christina Miller Fellowship, which was followed by a Ramsay Memorial Fellowship, a L’Oréal-UNESCO For Women in Science UK & Ireland Fellowship and a UKRI Future Leaders Fellowship. The work of Jenni and her team has been recognised by several awards including the 2019 Macro Group Young Researcher Medal and the 2021 RSC Sir Edward Frankland Fellowship.

 

You’ve recently started your own group, what are the big research question/s your group will be focussing on?

My research group focusses on enhancing polymer sustainability, underpinned by new catalyst design. We explore cooperative catalysis, where multiple metals work synergistically to improve catalyst performance. Our work spans from molecular to macromolecular levels, and aims to develop new sustainable materials, understand how catalyst design influences the polymer structure and material properties, and advance recycling processes.

What inspired you to get into science?

I’ve always had a passion for science, and as a child, my best friend and I would play “potions” by mixing various bubble baths, shampoos and toothpaste. Unfortunately, this once included her dad’s expensive aftershave! However, it wasn’t until the second year of my undergraduate degree that I realised I wanted to pursue research. I was fortunate to spend a summer as a Carnegie Scholarship student in the Mulvey group, where I created a molecule that had never been synthesised before. This experience opened my eyes to the creativity and design that are inherent in science, and from that moment, I was hooked! What continues to inspire me are my incredible team, the opportunity to continuously learn more about science, and the knowledge that science can play a crucial role in addressing global challenges and environmental concerns.

What advice would you give to those who are seeking their first group leader position?

My main piece of advice is to find a good mentor. I have been incredibly fortunate to have had fantastic mentorship throughout my career. My mentors have given me with invaluable guidance, support and encouragement. They have continuously pushed me to step out of my comfort zone and to pursue opportunities I might once have thought were beyond my reach. Early in my career, I made a commitment to myself that I wouldn’t talk myself out of applying for new opportunities – and I’ve been amazed by some of the results! I also believe that it’s important to build resilience. During the tough times, I turn to a few iconic poems and speeches that remind me of the importance of character and perseverance. One of the best pieces of advice I’ve been given is to truly celebrate your successes, no matter how big or how small! It can be easy to move on to the next thing, but pausing and taking time to acknowledge achievements, both for yourself and your team, can be both motivational and uplifting.

Design strategies for organelle-selective fluorescent probes: where to start?

Samira Husen Alamudi and Yong-An Lee

Graphical abstract: Design strategies for organelle-selective fluorescent probes: where to start?Tracking changes inside cells is essential for understanding both normal biological functions and disease processes. Fluorescent probes are valuable tools for this purpose, offering advantages over genetically encoded alternatives. Despite significant advances in organelle-specific probes, several challenges persist. This work highlights key design strategies for such probes, including cellular uptake mechanisms and the interplay between the properties of the target organelle and the physicochemical characteristics of the probe. Additionally, it showcases recent advancements and  addresses current challenges in the development of organelle-targeted fluorescent probes.

Meet the Principal Investigator

After completing her BSc at Universitas Indonesia (UI), Samira Husen Alamudi received her PhD in chemistry from the National University of Singapore (NUS) in 2015 under the supervision of Prof. Young-Tae Chang. She then pursued postdoctoral studies at NUS and later worked as a Research Fellow at the Agency for Science, Technology and Research (A*STAR), Singapore, with Prof. Young-Tae Chang and Prof. Ichiro Hirao until 2021. She subsequently worked in the biotechnology industry before joining UI in 2023, where she is currently an assistant professor. Her research interests include the development of small fluorescent probes for monitoring intracellular dynamics in native cellular environments.

You’ve recently started your own group, what are the big research question/s your group will be focussing on?

Our research focuses on advancing the development of fluorescent probes for monitoring intracellular dynamics in native cellular  environments. While numerous target-specific probes exist, many still face classic challenges such as poor selectivity, membrane impermeability, high background noise, and instability in complex biological systems. We aim to address these limitations by leveraging structure-function relationships to design effective labelling tools. Ultimately, our goal is to contribute innovative molecular tools that can drive new biological discoveries and therapeutic advancements.

What inspired you to get into science?

My fascination with science began at an early age when I asked my father, “What makes us human?” and “What lies behind the moon?“, to which he responded with “Those are such big questions for such a little girl“, only fueled my curiosity further. During high school, I became deeply intrigued by how biomolecules interact to create life’s complexity. This passion for chemical biology solidified during my doctoral studies when I first encountered the power of fluorescence imaging. The ability to visualize cellular processes in vibrant colors was captivating, revealing hidden aspects of biology behind beautiful images. This further inspired me to develop tools that could aid in disease diagnosis, drug discovery, and beyond.

What advice would you give to those who are seeking their first group leader position?

Starting a research group is both an exciting and daunting transition. To succeed as a group leader, it is essential to embrace both the scientific and leadership aspects of the role. One of the most important lessons I have learned is the value of prioritizing mentorship and building strategic collaborations. Investing time in fostering a supportive and collaborative environment helps students thrive, while establishing meaningful partnerships accelerates progress and creates new opportunities. Science is a long journey, but with passion and perseverance, it is undoubtedly a rewarding one.

Meet Oisín N. Kavanagh: New Principal Investigator

We are delighted to introduce the first contribution to our New Principal Investigators collection.

Read the paper

Cystine crystal nucleation and decay in the context of cystinuria pathogenesis and treatment

Kimberley Noble and Oisín N. Kavanagh

Meet the Principal Investigator

Oisín N. Kavanagh is a pharmacist and Senior Lecturer in Pharmaceutics at the School of Pharmacy, Newcastle University and Senior Fellow of the Higher Education Academy. He received the Gold Medal from the Pharmaceutical Society of Northern Ireland in 2017 and completed his clinical training in his hometown of Derry before moving to the University of Limerick to undertake his PhD. He was awarded a Fulbright scholarship to the School of Pharmacy, University of Michigan and was subsequently appointed to a Lectureship at Newcastle University in 2021. His research interests are centred around the relationship between drug physical properties and their pharmacokinetics. He is PI for multiple research streams funded by government and charitable organisations. This includes an EPSRC-funded project (EP/Y014596/1) investigating drug-induced crystalluria and a project funded by Action Medical Research/LifeArc focused on engineering new drug formulations for cystinosis, a rare disease.

Check out the video below where Oisín summarises his recent paper:

You’ve recently started your own group, what are the big research question/s your group will be focussing on?

The central vision for my team is to develop fundamental understanding to describe the relationships between drug supersaturation and pharmacokinetics. This has brought us to work on two applications (1) crystal engineering to modulate the pharmacokinetics of absorption and (2) contextualising supersaturation processes in the kidney with pharmacokinetics to predict drug induced crystalluria.

What inspired you to get into science?

If I cast my mind back, I can’t remember ever wanting to be anything other than a scientist. I suppose the path forward became a little clearer during my time at university, where I studied Pharmacy. There, I developed a solid foundation in pharmaceutical sciences and worked every summer in the research labs of Professor John Callan. This experience was formative for me.

What advice would you give to those who are seeking their first group leader position?

This is a difficult path and there are moments when things look bleak… in those times, try to remember why you’re doing this – and then get at it!
