I am currently working on my PhD at Terrestrial Ecology at the University of Bergen titled "Using UV-B-absorbing compounds in sporopollenin as a proxy for plant-received UV-B: a greenhouse- and field-experimental approach".

During my PhD I will research several key challenges of using pollen chemistry as a proxy for plant-received UV-B.
1. What are the problems surrounding the quantification of UV-B absorbing compounds and how do we solve them?
2. What is the importance of phenotypic plasticity compared to local adaptation on the UV-B-absorbing compounds signal?
3. Are the measurements of the UV-B absorbing compound signal under greenhouse conditions robust and comparable to this signal under natural/field conditions?

My main supervisor during my PhD is Alistair Seddon and Matthew Robson and Daniela Festi are my co-supervisors.

I am also a part of the chemical paleoecology subgroup of Terrestrial Ecology, PalaeoChem. Together we discuss our findings and methods regarding pollen chemistry, as well as discuss recent papers on pollen chemistry (including papers focused on the laboratory methods THM-GC/MS, FTIR and Raman analysis).
