Fieldwork in Mongolia
I had a fieldwork in vast and incredible landscapes in Mongolia from July to August. It is my first visit to Mongolia. Truly enjoyable. I would like to thank my Mongolian colleagues, their families, and their friends for their warm hospitality and support.
Visit to GFZ Potsdam and Participation in Goldschmidt 2025
After visiting the SIMS lab at GFZ (German Research Centre for Geosciences) in Potsdam, I attended the Goldschmidt 2025 Conference in Prague from July 6 to 11. The whole experience made me extremely happy.
