I am a researcher and educator specializing in new energy technologies, with a primary focus on solar energy. My work bridges physics, engineering, and artistic research, particularly inphotoelectrochemical energy conversion, colored photovoltaics, and nature-inclusive solutions to develop ecologically sustainable energy production.

I have extensive experience in dye-sensitized solar cells, including their fabrication on flexible substrates, electrochemical impedance spectroscopy, device physics modeling, optical characterization, accelerated aging testing, and degradation analysis, which gives a strong foundation for exploring diverse research questions in photovoltaics and electrochemical energy conversion.

Recently, my research has expanded into both theoretical and experimental studies of optical coatings for colored photovoltaics, with applications in building-integrated solar technologies. Large-scale solar energy integration into buildings and infrastructure is essential for the sustainable development of renewable energy, as it makes use of existing surfaces reducing land-use conflicts with agriculture, forestry, and nature conservation—an issue particularly close to my heart.

I also engage in transdisciplinary art-science research, using natural dye-based solar cells as both a scientific tool and a creative medium. By merging artistic research with scientific inquiry, we explore new ways of thinking and knowledge creation at the intersection of ecological sustainability, bioethics, materials, and energy production. This work explores how we can ethically engage with and attune to other species in the process of researching and developing new energy technologies, opening space for more inclusive and ecologically mindful innovation.

Extending this thinking into the design of future energy systems, I am developing new research on nature-inclusive, regenerative solar energy production. At its core is the question: How can we design renewable energy systems that not only minimize harm but actively restore nature?This means creating solar technologies that support biodiversity, regenerate ecosystems, and strengthen connections between humans, other species, and the landscapes we shape. It calls for a more caring and reciprocal approach to energy—one that integrates human and ecological well-being.

In 2025-26, I am a researcher member at Puistokatu 4, a vibrant multidisciplinary community of researchers and organizations. I welcome collaborations and conversations!
