PhD thesis defence by Antti-Jussi Kieloaho 3rd Feb 2017

Antti-Jussi has his thesis ready for defense on 3rd February 2017 at the Department of Physics, see:

Pay special attention to his last paper that binds soil, soil fungi and atmospheric processes together in a great way, well done Antti-Jussi!

New personnel in 2015-2016

We have got new people in the group! Dr. Bartosz Adamczyk joined the group and takes the charge of soil chemical analysis in NITROFUNGI project. See more on Bartek’s expertise in

PhD student Mari Mäki started to work on VOC-fluxes in our field site in the summer 2015. See more
