These are the areas we keep editors and statisticians in, which is not the same as the limit of what we can read. If your field is not here, ask: the answer is either the name of the person who would take it or an honest no.
We match on subfield rather than on discipline. A cardiology trial and a structural biology paper are both life sciences and have almost nothing in common to read for, so they go to different people.
Statistical review is assigned separately to a biostatistician, because noticing that a test does not fit the design is a different skill from noticing a dangling modifier.
Send it in the language you wrote it in. Translation is done by a specialist with a research degree in your field rather than by a general translator working from a glossary, and the language editing is included.
We correspond in English, 日本語, 中文, 한국어, Bahasa, Português, العربية.
