I am a PhD candidate in the field of Geoinformatics, and I am expected to submit articles in related ISI journals. During the last years, Helena and Isabella Merschdorf have helped me with the English proofreading of my manuscripts, including grammar corrections, formatting, and commenting on my manuscripts, all of which helped me to better clarify my arguments and to improve the quality of the manuscripts. They also helped my sister, who is doing her PhD in the field of solid-state physics, with the English of her manuscript, including corrections and formatting, and getting her manuscript to be “accepted without change” in the related ISI journal. Hereby, I thank them for all the work they have done for my sister and me, to save our time, and let us submit our manuscripts with more confidence to the journals. Thanks, Helena and Isabella, I am very grateful for your help, and I will use your services again. I highly recommend them to academics to save their time and have higher quality work.
