Jessica edited a manuscript for me, and I would like to recommend on her excellent editing skills. Jessica took on herself a much more complicated and subtle task than correcting grammar or syntax errors – she elegantly improved the readability of the manuscript, connected paragraphs better, and made the whole reading experience easier and more fluent. This was an important and complex task. The manuscript was accepted to an important journal in my field, and I am grateful to Jessica for her important and professional contribution. As a final word, I would like to express my appreciation to Jessica's friendliness: Working with Jessica is professionally beneficial but also always pleasant and constructive. I will definitely ask for her help again in the near future!

After two years of staring at my thesis, there was no way for me to do the editing on my own. They did an excellent job cleaning and tightening up my writing, so that I was quickly able to submit my thesis ahead of schedule. I truly owe them a debt of gratitude for her help in getting me one step closer to graduation.

Thanks for editing two of my manuscripts and a grant proposal. You helped me form more natural sentences and use the right vocabulary.

Jessica has corrected the english for two of my articles, one published in Animal Behaviour and the second one still under preparation for a submission for publication in Oecologia. For both of these articles, Jessica was really efficient and professional. Her assets are her education in Biology, her experience in peer-reviewed and the fact that english is her mother tongue. So, while the english is perfectly corrected (grammar and spelling) the meaning is unchanged. Moreover, the delay of correction is very short so it does not lengthen the process of publication. For all these reasons, I highly recommend this service for the english correction of your articles in Biology.
