Research Careers in Finland: PhD Vasuki Durairaj´s career path was not straightforward
Case - Published 16.1.2025
One´s career path does not always follow a straight line. Trying different disciplines guided PhD Vasuki Durairaj´s career as a researcher towards biomaterials. Diverse challenges and opportunities have helped her to grow as a scientist.
“My career story is truly a sum of serendipitous accidents,” begins PhD Vasuki Durairaj, reflecting on her journey towards the field of biomaterials.
Originally from India, she started her career with a Bachelor’s degree in Electrical and Electronics Engineering. While looking for a Master’s program in Europe to continue her education, Aalto University’s “Micro- and nanotechnology” program caught her eye. Admission to the program was her gateway to Finland in 2011.
“The program offered modules in microelectronics, optics, and microfabrication. I started with the microelectronics module, but quickly realized it wasn’t where my heart was. The flexibility of the Finnish education system allowed me to explore and ultimately complete my Master’s degree with majors in both optics and microfabrication”, she states.
She then pursued her Doctoral Studies at the Aalto University’s School of Chemical Engineering. The focus of her doctoral research was the development of electrochemical sensors for medical applications, using cellulose- and carbon-based hybrid nanomaterials. This was her introduction to the world of biomaterials.
Making a better future
Today, she works as a Research Scientist at VTT Technical Research Centre of Finland, in the ‘Biomaterial processing and products’ team. Her role includes both academic and customer-oriented projects, focusing on developing biomaterials—especially cellulosic materials—for high-value applications.
“Our research aims to develop sustainable alternatives for fossil-based materials in several application fields including packaging, textiles, construction, and electronics. I feel extremely privileged to be a part of a research organization that respects and fosters both my personal and professional values and skills”, she says.
Vasuki sees a bright future for bioeconomy: “The world is waking up to the consequences of relying heavily on fossil fuels. Hopefully, it is not too late to turn things around and find more sustainable solutions for our future and build a strong bioeconomy. However, the change is not going to be accomplished easily”, she continues.
She states that the awareness about sustainable solutions must increase worldwide, and fossil-based products must be regulated more strongly to make sustainable alternatives more tempting and affordable.
Tips for young researchers
Her advice to young researchers is straightforward: “Be passionate about your work, think outside the box and remember to always consider the sustainability and environmental impact of your research” she says.
For Vasuki, the role of mentors during her career has been significant. Her supervisors and research advisors during the doctoral studies and research career have both inspired her and helped her develop vital researcher skills. “In addition to carrying out my independent research tasks, I was encouraged early on to participate in proposal writing and consortium co-ordination activities for large jointly funded projects. These skills have been the foundation of my career at VTT”, she explains.
