Mid Sweden University’s focus on sustainability drew him to Sundsvall

Tell us about your background and what you focused on before joining Mid Sweden University?

I am originally from Dehdasht in Iran — a geographically diverse country that includes high mountains, dense and sparse jungles and deserts. I’ve lived and worked in both cooler mountainous areas, where summer temperatures average around 25°C, and in much hotter regions where they can rise above 50°C. Here in Sundsvall, I’ve experienced yet another contrast, with winter temperatures dropping below -15°C.

Before joining Mid Sweden University, I worked as a senior chemist at a company that produced Ziegler-Natta polyethylene. I was responsible for quality control and process improvement, which gave me valuable insight into industrial processes.

Why did you choose to pursue your PhD at Mid Sweden University?

I’ve always felt a personal responsibility to contribute – even in small ways – to the well-being of our planet. In my previous job, I witnessed the effects of air pollution in industrial environments firsthand, which made me more aware of environmental issues. When I got the opportunity to work with Camfil AB on air filtration technologies, it aligned perfectly with my values and felt like a meaningful step. Mid Sweden University’s strong focus on sustainability and its supportive research environment made it the right place for me.

What is the focus of your research?

My research focuses on modifying the surface of cellulose and its derivatives to enhance their triboelectric properties. The goal is to develop triboelectric air filtration systems that attract and capture airborne particles using electrostatic forces. Unlike traditional filters, which physically block particles and often restrict airflow, this approach aims to offer both efficient filtration and improved energy performance.

What is your impression of Mid Sweden University and Sundsvall so far?

Mid Sweden University offers a warm and collaborative academic environment. I feel fortunate to work with supportive faculty and colleagues, and to have access to well-equipped research facilities. Even though it’s a relatively young university, I believe it has a bright future and will continue gaining recognition both in Sweden and internationally. Sundsvall, with its natural beauty and calm atmosphere, provides a great quality of life and an excellent work–life balance – something I appreciate more every day.

What has been the most exciting or challenging part of your PhD journey so far?

One of the most exciting parts has been working on a project supported by a company with a strong interest in air filtration. Although there is significant academic research on triboelectric filters, real-world applications are still limited. The challenge of helping bring this technology closer to practical use is both demanding and inspiring. I hope my contribution will be a small step toward making this type of filtration more accessible and applicable.

How does your research contribute to the broader field or to practical applications?

My research supports the development of environmentally friendly materials by improving the triboelectric properties of cellulose. The long-term goal is to help design air filters that are more efficient and sustainable. Although the field is still in its early stages, I hope my work can help bridge the gap between lab research and everyday applications, making clean air solutions more attainable.

What is it like living and studying in Sweden compared to your home country?

Living and studying in Sweden is quite different from my experience in Iran. The academic environment here encourages independence and critical thinking, which I find very enriching. At the same time, I deeply value the strong sense of community, hospitality, and cultural richness found in Iran. Both places have taught me different but equally meaningful lessons.
