2018 Master thesis (II) at the University of Bergen and Utrecht University"Do pollen grains get a suntan: An investigation into the drivers of variation in UV-B-absorbing compounds in pollen grains to develop a proxy for solar radiation"

2016-2017 Master thesis (I) at Utrecht University"Towards climate tolerant crops: The effect of beneficial microbes on thermomorphogenesis in A. thaliana"

2016 Bachelor thesis at the University of Amsterdam"Calibrating modern phytolith assemblages with vegetation composition in tropical forests"

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?

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 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).
