Two Tech students are visiting Copenhagen this week during the UN’s international climate change conference. One of them is Adam Airoldi, a graduate student in forest ecology and management. His advisor is Associate Professor Andrew Burton (SFRES). Airoldi is doing research in Norway this semester, collaborating with the Norwegian Institute for Nature Research, on changes in the alpine tree line around a small copper-mining town in central Norway. Airoldi earned his bachelor’s in forestry in 2008. He is in Copenhagen on a graduate travel grant from the Ecosystem Science Center.
