‘David says it would have
helped him to have a teacher
who was a point of contact
for students with LGBT
issues.
While he had many teachers
who made a huge difference
in his scientific development,
this was not related to
finding his LGBT identity’

8. ‘You are mistaking us for people who give a ****.
Your sexuality is NOT important vis-a-vis your job’.
‘So your fellow scientists don't give
a shite about your sexuality,
just your research credentials
and publication records?
Isn't that equality?’
Meritocracy or ‘Don’t Ask Don’t Tell’?

‘A lot of people worry that there will be unconscious bias against them in
the job hunting process. This should be something we are happy to
discuss as scientists. It should just be a part of life.’
Female Researcher (Anon):

13. A junior researcher’s supervisor can have a lot
of influence on their prospects, many
researchers think it is necessary to avoid
personal details.
‘If you can’t even have a conversation with a
colleague about who you spent the weekend

14. ‘Throughout my academic life in Chemistry,
I've found it normally has a
very conservative, macho culture.
Any sexuality related issues
are met with embarrassment
or sometimes hostility,
more so than other academic areas.
It doesn't help on an emotional level,
leading to feelings of isolation
perhaps leading to giving up
on a science career.’
