I am autistic and I hold a bachelor's degree but, sadly, had to quit grad school due to health reasons. I have a special interest in a subfield of hematology-oncology and have read a fair amount of research papers about that subject. I have some – hopefully – sound questions that I'd like to get answered but these are very precise questions regarding a specific subject that only a couple hundred researchers know about (so no luck getting answers elsewhere). Since I am not in academia I can't post them in the comment section on ResearchGate (which would have been more practical).
How appropriate is it for me to e-mail the corresponding author to ask for details about their paper and/or ask for their insights about a possible research gap? Should I mention that I am autistic with a special interest in their research subject?
