Curriculum Vitae

Academic Qualifications

2014

Master in Environmental Science (M.Sc. Geoökologie), TU Braunschweig. Master thesis: “Rekonstruktion der Umweltveränderungen des Kaschmir-Tals im Zeitraum der letzten 5000 Jahre mittels einer Diatomeenanalyse aus dem Manasbal See, Indien“, Institute of Geosystems und Bioindication.

2011

Bachelor in Environmental Science (B.Sc. Geoökologie), TU Braunschweig. Bachelor thesis: “Ursachen für die Auflösung von Diatomeenschalen im Sediment am Beispiel ihrer Erhaltung in Sedimentkernen des Tibet-Plateaus“, Institute of Geosystems und Bioindication.

 

Work Experience

2016 – 2017 Methoden der Sedimentanalyse, module: Aquatische Ökosystemanalyse I: Langzeitmonitoring, WS2015/2016 and WS2016/2017, Bachelor Geoökologie/Umweltnaturwissenschaften, TU Braunschweig.

Research Interests

My research interests are mainly focused on environmental science, paleoecology and limnology. Diatoms and ostracods from limnic systems are used as bioindicators for environmental assessment and reconstruction.
