Alkuin Maximilian Koenig (ESR1)

Alkuin studied General Physics at the Universidad Mayor de San Andrés (UMSA) in Bolivia. Early on in his studies, he started participating in the local Atmospheric Physics Lab (LFA), with which he maintained a strong collaboration after obtaining his degree. As a local staff member of the LFA, he participated in the SALTENA campaign by the University of Helsinki, focused on the topic of New Particle Formation (NPF) in the Bolivian Andes, and eventually attended the Hyytiälä winter school, working on NPF growth rates.

In parallel, he got involved in the topic of atmospheric mercury through a data set sampled at the high altitude (5240 m) Chacaltaya GAW station in Bolivia by the LFA and the Institute of Environmental Geosciences (IGE), under the supervision of Aurélien Dommergue. Through this data, he explored seasonal patterns of atmospheric mercury and tried identifying mercury sources and sinks in South America, using as tracers some of the other magnitudes measured continuously at the CHC station (e.g: Black carbon, Carbon monoxide, Carbon dioxide).

In this context, he got invited in fall 2018 as a scientific visitor to the IGE and started a Master’s degree in earth sciences at the University of Grenoble (UGA) the following year. Towards the end of the first year of this program, he learned about the GMOS train and saw an opportunity to keep exploring and contributing to the field of atmospheric mercury.

Saeed Waqar Ali (ESR9)

Mercury has been a primary focus of my previous work, some of which were undertaken as part of the mercury research group in Pakistan to estimate mercury exposure in the workplace and from the use of mercury containing products for the ratification of Minamata Convention on Mercury.

I did M.Phil. in Environmental Science from Quaid-i-Azam University Islamabad and during my dissertation, I studied the spatial and historical atmospheric mercury trends in the northern and mid-range regions of Pakistan using tree rings, a project that was done in collaboration with Guangzhou Institute of Geochemistry, Chinese Academy of Sciences. The aim was to study the influence of global Hg atmospheric cycling as well as local Hg emission sources on the remote and mid-range regions of Pakistan.

When I learned about the GMOS-Train project, I immediately realized its relevance to my previous study on tree rings which was also based on the exchange of Hg between forest canopies and the atmosphere. I knew that this is an ideal opportunity for me to expand my understanding of the underlying mechanisms of the inter-compartmental exchanges and that this project will play a key role in enhancing my scientific knowledge on the topic.

The investigation of terrestrial Hg pools and intercompartmental exchanges with atmosphere and aquatic systems as part of the GMOS-Train project at the Jožef Stefan Institute will be a step toward a better understanding of the role of vegetation in the global Hg biogeochemical cycling.

David Amptmeijer (ESR13)

I studied Molecular Biology for my bachelor at the University of Groningen (RUG) with a minor in Arctic Biology at the University Institute Svalbard (UNIS).
For my MSc, I switched to Marine Biology and did two major projects. The first was in Iron Binding Ligands in the Transpolar Drift working at the Dutch Institute for Marine Research (NIOZ) and the second project was in Bioaccumulation of persistent organic pollutants in Ryder Bay, Antarctica working for the University of Wageningen (WUR) in cooperation with the British Antarctic Survey (BAS). I finished my MSc with a thesis about persistent organic pollutants.
During my studies, I developed a strong interest in computational biology and modelling as this allowed me to investigate and evaluate the obtained data in great detail. I made models for several projects, including analyses of salt marshes for coastal protection, the importance of manganese
nodules for deep-sea ecosystem structure, and the flux of persistent organic pollutants.
I most enjoyed the pollution modeling because of the environmental relevance. Because of this, I continued working in this field and got a job at the Helmholtz-Zentrum Geesthacht in modeling the bioaccumulation of methylated mercury. This job allowed me to successfully apply to GMOS-Train ESR13 in the same subject.
