Download celebratory graphic2025 RSC Apprentice Prize: awarded for excellence in peptide chemistry, and championing sustainability and STEM advocacy.

Christina’s role focuses on making new peptides and improving existing ones to help them stay in the body for longer. Peptides are small proteins made from amino acids that are used medically to treat hundreds of conditions, including diabetes, cardiovascular diseases, and even cancer. The challenge with peptides is that they break down quickly in the body, so chemists engineer them to last longer by adding linkers and unnatural amino acids. These disguise the peptide so that it can reach the part of the body it needs to treat. For example, there’s exciting work on engineering peptides to carry medicine to specific areas of the body to treat cancer.
Every day is different for Christina. She is typically in the peptide lab synthesising molecules and developing what could become life-changing medicines in the future. Her role means that she is always working on different projects, trying new things and continually learning.
Promoting STEM careers, apprenticeships and inclusivity are important to Christina. She leads an internal early careers research group with over 1,000 members, and is part of various other groups. She also leads an innovative and exciting research project to support AstraZeneca’s bold sustainability goals to be net zero by 2030.

Q&A with Christina Dumitriu Jackson
How did you first become interested in chemistry?
I’ve always had a passion, energy and excitement for science. I did A-levels in chemistry, biology and psychology alongside an Extended Project Qualification (EPQ) in digital medicine. With two parents in the NHS, I was inspired to see the impact you can have by being a healthcare professional. I realised I could impact patients, change lives and the world around me through science.
I was all set to study a pharmacy degree and had received offers from Russell Group universities. I was unaware that degree apprenticeships existed, where I could combine work and study. One evening I was browsing and saw my current role advertised. I was keen to apply as active learning has always been my style and, during my A-levels, I had already combined studying with working at a supermarket.
¾ÅÖÝÓ°Ôº has opened up a world of opportunities for me. It’s allowed me to dive into groundbreaking research – especially in peptide synthesis, which plays a crucial role in drug development. Through chemistry, I’ve been able to collaborate with experts across different fields, making my research more impactful.
My background in chemistry has helped me work on developing and refining new technologies through making synthesis methods more sustainable. All of this has not only deepened my understanding of the field but also opened doors to entrepreneurial ventures and broader applications of my work.
When I mentioned an apprenticeship, especially without a degree in front of it, my teachers, parents and peers were confused as to why I was looking elsewhere when I had been accepted into top UK universities. My parents had the traditional view that university was the only option for success in the world of medicine. However, I went ahead with the application and at the assessment day, I knew this was the environment that I would excel in. I am studying towards my degree in chemistry, earning a salary and having my university fees paid by my employer.
Tell us about somebody who has inspired or mentored you in your career
I’ve been lucky to have two exceptional mentors who have supported me from the very beginning of my career to where I am now. They have consistently gone beyond the role of manager, challenging me, guiding me and investing in my growth both professionally and personally. They didn’t just give me feedback – they gave me space to reflect, pushed me to step outside my comfort zone, and trusted me with responsibility before I fully trusted myself.
What’s meant the most is their willingness to have difficult conversations that helped me grow, while also making it clear they believed in me. That kind of support, especially early in your career, is rare, and it’s shaped not only my confidence but also my standards for leadership and mentorship. I carry those lessons with me in how I work with others and how I show up in the spaces I care about.
What motivates you?
What motivates me is the opportunity to create a meaningful impact, whether that’s through advancing scientific discovery, mentoring others or driving inclusivity in spaces where it’s long overdue. I’m driven by curiosity, a deep sense of purpose, and the desire to leave things better than I found them. Knowing that my work can help solve real-world problems and open doors for others keeps me focused and energised, even in challenging moments.
What advice would you give to a young person considering a career in chemistry?
Do it! ¾ÅÖÝÓ°Ôº is at the forefront of science and is always evolving and changing. It will keep you on your toes and challenge you in many ways, but the best part is that you can change lives and really make a difference with a career in chemistry. There’s so much more out there than I ever imagined.
What has been a highlight for you (either personally or in your career)?
A key highlight in my career was being invited to present to the AstraZeneca board as a degree apprentice. It was an incredible opportunity that pushed me outside my comfort zone and helped me grow in confidence, communication and strategic thinking. Sharing my perspective in that space affirmed the value of my voice and strengthened my drive to bridge science with leadership and impact.
What has been a challenge for you (either personally or in your career)?
Initially, it was challenging to branch out and not follow the rest of my peers to university. However, I decided to take the risk and I haven’t looked back. As a degree apprentice, the first-hand experience and professional and personal development in the workplace is invaluable. I am taught and surrounded by experts in the industry who mentor me and help me grow.
Why do you think collaboration and teamwork are important in science?
Collaboration and teamwork are essential in science because complex, challenging societal problems need us all to come together to solve them. Scientific progress depends on the integration of diverse expertise and perspectives. Diversity of thought isn’t just a principle – it’s a proven advantage. McKinsey’s 2020 report found that companies with greater ethnic and gender diversity on executive teams were 25% more likely to outperform financially. In science, this leads to more informed decisions and more impactful results.
What is your favourite element?
Gold is my favourite element because of its chemical stability and versatility. Its resistance to corrosion and excellent conductivity make it essential in fields like medicine and electronics. I find it fascinating how an element so often associated with luxury has such practical, scientific value.
