Research Careers in Finland: Ville Rissanen studies biomaterials at VTT
News - Published 20.12.2024
Senior Scientist Ville Rissanen’s interest in natural sciences sparked during high school, guiding him towards a career in research. His studies in biochemistry at the University of Helsinki opened the door to the world of biomaterials research. Now he works at VTT Technical Research Centre of Finland.
Rissanen joined VTT Technical Research Centre of Finland nine years ago to do his master´s thesis. Since then, he has held a variety of roles, including completing a PhD as part of his work duties.
“The work has never become monotonous, and the diversity and variation in tasks are its the best parts,” Rissanen shares. He has dedicated his career to applied biomaterials.
His path towards biomaterials started as a deep fascination with nature and natural sciences.
“Since I was a child, I have been a ‘researcher type’, and I started studying biology and chemistry in high school. This eventually led to studying biochemistry in University of Helsinki. I wanted to combine practical work with the goal of making a positive impact on the world,” Rissanen explains.
Initially, he aspired to work with medical research, but during his studies, his interest shifted toward green technologies and the development of biomaterials. He graduated from the Master’s Program in Bioproduct Technology.
Research is much more than lab work
Currently, Rissanen’s primary responsibilities involve research-related tasks, although part of the year he also takes on project management and funding coordination roles. These responsibilities require overseeing projects, schedules, and practical details. On the research side, his work includes reading and writing articles, and of course also conducting various laboratory experiments focused on biomaterials research and development.
Networking and brainstorming new projects with academic and industry partners are also vital components of his work. Additionally, international conferences provide opportunities to present research findings and connect with experts in the field.
“In addition to this, I also mentor younger researchers and master’s thesis students in some projects”, Rissanen adds. “A typical workweek can look very different depending on the roles and tasks I take on.”
Over the years, both Rissanen’s tasks and research topics have also been diverse.
“In my career, I’ve worked on developing porous foam filters and dense water purification membranes One interesting application I’ve also studied is gel structures that retain water and support the functions of living cells”, Rissanen lists.
His work in applied biomaterials research has mainly focused on developing and studying new cellulose-based materials. Recently, his research has extended to a deeper understanding of the structure and function of plant cell walls.
Rissanen emphasizes that using renewable materials like cellulose derived from wood, instead of fossil-based raw materials, is a critical component of climate and resource sustainability. Research and new applications have the potential to address global challenges and mitigate their harmful impacts.
Although cellulose-based products replace fossil resources, forests also serve as carbon sinks. “In the development of wood-based materials, we should focus on creating higher-value and more sustainable products so that we can get more out of less materials”, Rissanen concludes.
