Fellow Spotlight: Dr Sonia Gera on developing materials to heal and fix bones

Dr Sonia Gera is a UKRI Research Fellow in the Department of Materials. Her research investigates materials that can fix broken bone and help them heal while preventing infections at the same time. These materials are nature inspired, are made of  safe and biocompatible ingredients. In this blog post, she shares more about her research, what she enjoys about her work and what she likes to do outside of research. 

What inspired you to become a Materials Scientist?

During my studies in Pharmaceutical Science, I witnessed the crucial role of materials in the delivery of medicines to address real world health challenges. I have always been passionate about understanding the bone healing process and exploring how materials can play a transformative role in it. My dream is to one day invent a novel material that not only repairs bone fractures and defects but also accelerates healing while providing long-term relief. The idea of developing materials which can mimic the tissue and their ability to interact with biological surface has truly inspired me to work in material science. This multidisciplinary field has allowed me to build on my previous knowledge and skills to bring innovative solutions to critical conditions such as bone repair. The potential of materials to bring meaningful changes in society makes it a perfect path for me.

How would you explain your research to someone outside the field?

Imagine if surgeon could use a biodegradable glue instead of metal screws and plates in fixing bone and bone implants in case of broken bones. This glue will not only hold it under wet conditions, but also supports the body’s healing process by encouraging the new bone growth and stopping all the harmful bacteria to prevent infections-all without the need of antibiotics. I am working on developing such glue like materials that can fix the broken bone and help them heal while preventing infections at the same time. These materials are nature inspired, and are made of safe and biocompatible ingredients.

Why did you study this area and why is it important?

Bone repair and infection prevention is an important research area demanding novel solutions because millions of people get bone injuries every year globally from trauma, osteoporosis and bone diseases. The traditional methods suffers from challenges of slower healing, infections and  additional surgeries. By developing bioinspired materials we are improving patient outcomes, reducing recovery time and addressing global challenges in sustainable way.

How could this research make an impact?

Adhesive material which can replace metal screws and plates in clinics and supports bone healing, controls infections without antibiotics has the potential that can go beyond lab and transform the how bone injuries and infections are currently treated. This will reduce the treatment cost, improve patient outcomes and quality of life.

Who do you collaborate with at Imperial and beyond?

My research thrives on collaborations as it involve multidisciplinary approach. I work close with experts and colleagues working in area of material science, polymer chemistry, bioengineering and microbiology. This includes researchers and team from Department of Materials, Department of Bioengineering and Faculty of Medicine. Beyond imperial, I collaborate with clinicians and their feedback ensures that my research aligns with the real-world applications. I also connect with industrial partners and innovation hubs which can help me translate my research into prototypes for preclinical testing. I’m always excited to connect with others working in similar areas. If you’re interested or involved in related research, let’s get in touch and collaborate!

What do you enjoy most about what you do?

What I enjoy most about my research and work is the opportunity to create solutions that can impact patient’s lives. I also like creative aspect of my work, experimenting with the different materials,  their testing, and discovering new ways to make them work better for application. It is like solving a complex puzzle with number of elements, each one of which can have real time impact. The best part is working with brilliant minds in the team is something I cherish each day being at Imperial.

What do you enjoy outside of research?

Outside research I love doing things that help me get relaxed and recharged. I like being in nature activities like long walks, hiking, visiting scenic spots that can help me clearing my mind. I also like travelling and exploring new places in London. I do enjoy watching movies, listening to music and reading  books on personal growth.

What’s something your colleagues would be surprised to learn about you?

My colleagues will be surprised to learn that I  am a big foodie! My curiosity sometimes spills in my kitchen as I love to experiment with food and recipes. I am always ready to try all the unique vegetarian dishes whenever I travel.

Five skills I’ve developed since joining Imperial

In this blog post, our second year undergraduate student Fahmin shares five skills she has developed since joining the Department of Materials, Imperial College London. 

For me, Materials Science is an exciting field that combines discovery, creativity and innovation. Since joining Imperial, I’ve come to appreciate just how impactful materials science can be. It’s more than just understanding how things work it’s about exploring why materials behave the way they do and how they can be enhanced to solve real-world problems. Whether it’s improving materials for electric vehicles or developing sustainable solutions, materials science plays a key role in shaping the future.  

I’m currently in my second year studying Materials Science and Engineering at Imperial College London and I feel I’ve gained key skills to push boundaries and think about science for the future. Here are five key skills I’ve gained:

Solving problems like a pro 

Materials science often feels like solving intricate puzzles. So far, I’ve learned how to break down complex challenges, analyse them, and find innovative solutions  For example, in the materials selection module, I’ve learnt how to evaluate different properties to identify the most suitable material for a given application. This process has taught me to think critically and creatively, giving me confidence in tackling challenges across both my academic and personal life.  

Hands-on experience in labs 

One of the highlights of studying materials science at Imperial is the practical, hands-on experience. Through labs, I’ve worked with advanced tools such as tensile testing and have performed mechanical tests such as four-point bending to explore the strength of materials under stress. These experiments bridge the gap between theory and practice, showing us how materials behave under real-world conditions.

Mastering data and visualisation  

Data plays a critical role in materials science, and the undergraduate course has helped me develop strong analytical skills. I have used Excel to interpret results from techniques like XRD, EDX, and X-ray photoelectron spectroscopy (XPS). Visualising and analysing data has helped me understand materials’ structure, composition, and surface chemistry. Turning raw data into meaningful insights has been one of the most rewarding aspects of my studies.

Communicating with confidence

Understanding complex material is one thing but explaining it to others is equally important. We’ve worked on interdisciplinary projects, such as our end-of-year design study project at the end of the first year, where I worked with a team of 12 students to design a machine that compresses powders and measures hardness values.

This project combined CAD software, coding and Arduino programming to bring the design to life, which encouraged us to have an effective line of communication in the team. This helped us to ensure we were working efficiently, and that any issues could be addressed quickly and with confidence.

Becoming resilient 

Our projects don’t always work on the first try! While working on our end-of-year design study project, we experimented with multiple approaches and tackled various challenges before arriving at our final design.

At the end of the project, we had to present our final work to two CEOs, our teaching faculty, and the entire cohort. Although this initially felt daunting, the communication and resilience skills that I developed throughout the year-long project gave me the confidence to share our ideas and my contributions to the team.

Overall I’ve found that studying Materials Science at Imperial is not just about understanding metals or ceramics; it’s about developing skills that prepare you to tackle challenges, communicate effectively, and make a meaningful impact on the world.
