Minna Väliranta


Description of research and teaching

I am a palaeoecologist with extensive experience in reconstructing past environmental changes from lake and peat sediment archives. My special expertise is the plant macrofossil method. After completing my PhD in geology in 2005, I have coordinated several research projects funded by the Academy of Finland and the University of Helsinki. I established my own Palaeopeatland reaserch group in 2010. Currently I coordinate two Academy of Finland-funded Arctic palaeopeatland projects. My current research interest is to investigate ecosystem responses to climate and environmental change and associated biogeochemical feedback mechanisms. The motto is “Past is the key to understanding the future”. All research outcome is disseminated widely through various media.

Throughout my work history I have extensively collaborated with a large and interdisciplinary group of scientists. Numerous different projects and the changing combination of co-workers have provided me with the possibility to build up a broad network of colleagues and excellent genuine connections to several research groups worldwide. I am devoted to educating a new generation of academics to meet challenges in the research field of environmental science by providing teaching, supervision and by promoting international connections.
