I am currently working on my PhD at the EECRG 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 challanges of using pollen chemistry as a proxy for plant-recieved UV-B.
1. How important are ‘within-tree’ variations of UV-B-absorbing compounds and how does this relate to local shading effects?
2. What is the importance of phenotypic plasticity compared to local adaptation on the UV-B-absorbing compounds signal?
3. In what developmental stage are the pollen most sensitive to changes in UV-B radiation?
I am also a part of the chemical paleoecology subgroup of the EECRG, PalaeoChem. Together we discuss our findings and methods regarding pollen chemistry, as well as discuss recent papers on pollen chemistry (including papers focussed on the laboratory methods THM-GC/MS, FTIR and Raman analysis).
