It's for a former PhD student who is applying for a tenure track position at a US university.
This student is absolutely amazing and really lovely and has done loads of really difficult research.
I am concerned I will not sound superlative enough as I have heard that US references are really OTT. (sample phrase from one my own PhD supervisor read: "this person changed my life"). I know they like long references too!
What can I say to be accurate but not either overly British or that can be misinterpreted? Other than "you'd be mad not to employ her"?
This person has been a postdoc since but I know they were good at teaching when they were a PhD student and also a good lab mentor so I'm putting that in.
