My research group addresses plant biomass degradation and modification by filamentous fungi. We focus on various aspects of fungal physiology, molecular genetics and enzymology with the aim to provide sustainable biotechnology solutions. Our research has provided strong international contribution in the field of fungal and enzymatic degradation of lignocellulosic biomass.

One of my recent research interests is sugar transport in filamentous fungi, which is studied in my Novo Nordisk Foundation Ascending Investigator project MYCOFACT.

In addition, my research topics include:

• Molecular level regulation of plant biomass conversion in basidiomycete fungi
• Development of genome editing tools in basidiomycete fungi
• Elucidation of fungal carbon and aromatic metabolism
• Genome mining and characterization of novel plant biomass modifying activities for biomass valorization

Fellowships:

• HiLIFE Fellow (2023-2025)
• Novo Nordisk Foundation Ascending Investigator (2021-2026)
• Academy of Finland Research Fellow (2017-2022)
