Prof. Petri Pellikka is a professor of geoinformatics with a primary focus on remote sensing applications on land cover and the impact of human–nature interactions on the environment at the Department of Geosciences and Geography, University of Helsinki, Finland. He obtained his Ph.D. in Remote Sensing from the University of Oulu. His research group mostly applies optical remote sensing data, including hyperspectral data and laser scanner data. During the last decade, their focus has been on Africa, particularly on land cover and land use change caused by agricultural expansion and conservation and its impact on water resources, biodiversity, climate, and livelihoods. Earlier, he was involved in remote sensing research of glaciers as indicators of climate change and in developing remote sensing systems and correction procedures for radiometry and geometry of data. He is also a director of the multidisciplinary Taita Research Station of the University of Helsinki in Kenya, which provides research questions and solutions, from sustainability science to Earth system science, for the students and staff of his university and others.
Well done!
