Hi snawata,
I have worked on academic papers in a number of technical fields including medicine, environmental science, and cellular network design. I have assisted with PhD thesis writing and editing and have ghostwritten several textbook chapters for professional medical texts. I am not an expert in physics and math, though I do have plenty of experience at the college level with both. My skills are best applied in exactly what you need, which are grammatical editing and "readability." I'd be happy to work on this, would find the work interesting, and can deliver in 5 days (sooner if you are on a deadline).
Thanks,
Logan
