M.Sc. Jaakko Leppänen - PhD-student

Just as life on Earth was first born in the sea, so is my background as an environmentalist bound to the sub-aquatic world.
I am a research diver and a free diver, and as for the past decade, most of my occupational activities have been
connected to the underwater environment. My current PhD work is related to zooplankton and pollution. I am studying
the impacts of mine pollution towards cladoceran communities today and in the past; thus we don't only submerge into the deep lake bottoms,
but, in a way, deeper than the Trieste can go: inside the sediments and back in time.

I completed my MSc in 2012 at Helsinki University and begun the PhD research in 2015.
