“During my PhD Christina was a loyal constant. She helped me to correct my final PhD dissertation and edited all my scientific manuscripts before I submitted them. These papers have now been published in various journals – and not a single journal has ever criticized the language (e.g., grammar) in my manuscripts. Christina made the impossible possible and even worked on my texts at short notice, over weekends, and during her research expedition to Mongolia. In all cases I could always count on her to do high-quality work. She also provided me with numerous tips and suggestions on scientific English writing. Many of my colleagues now regularly have their manuscripts proofread or edited by her. Thank you, Christina! I look forward to continuing to work with you!"
