PhD Analytical Chemist | Scientific Writer | Stable Isotope Analysis | Academic Editor

Profile Summary

I am a PhD Analytical Chemist from the University of Duisburg-Essen, Germany, with expertise in stable isotope analysis, analytical chemistry, environmental chemistry, and aquatic ecosystems. My research has focused on analytical method development, compound-specific stable isotope analysis of amino acids, and the interpretation of complex scientific data. I have authored multiple first-author peer-reviewed publications in international journals and have extensive experience in scientific writing, manuscript preparation, literature reviews, data interpretation, and journal publication processes. I enjoy collaborating with researchers, universities, and industry partners on scientific writing, academic editing, research support, analytical chemistry, and environmental science projects. I am committed to delivering accurate, high-quality work while maintaining clear communication and meeting project deadlines.
