I am a native Spanish-speaking with a Doctoral Title in Theoretical Physics. I have more than 30 years of experience in teaching Physics, at the undergraduate and postgraduate levels, and as a scientific researcher. Since I work in theoretical Physics, I have an excellent background in mathematics. I am fluent in English (Bilingual) since I use it frequently as the common language in the scientific media. Is common in Physics to use the LaTeX editor, for writing research papers and academic documents, so I have vast experience editing texts in LaTeX, and making diagrams with Tikz. As a researcher in the field with many published research articles, and also a referee of scientific journals I have experience in editing and proofreading, technical, academic, and research writings, in Physics and other scientific or technical areas. I can ensure that any document I review or produce is done accurately, quickly, and efficiently. Any project you propose in the above areas of expertise will be managed with high-quality standards.
