Research interests
Andre Eger is a senior researcher at Manaaki Whenua – Landcare Research with a background in soil science, specialising in pedology, geochemistry, Quaternary geology and geomorphology, with particular emphasis on the New Zealand/South Pacific region. He has a broad perspective on landscape functioning and is able to ‘connect the dots’ between different domains in the environment (e.g., soil, biota, geology/geochemistry, hydrology, climate). He works on applied and fundamental questions including soil survey; sustainable soil use and ecosystem services; landscape evolution; biogeochemical interactions between soil, water, rock, and biota; and soils as archives of landscape and climate history.
He has an undergraduate degree in Physical Geography from the University of Leipzig (Germany) and a PhD in Soil Science from Lincoln University on natural drivers of soil and ecosystem fertility.
