Thank you THECORBYLOON.
PP claimed I was an organic chemist and given that I have academic qualifications in the subject, he was not incorrect as I was once a university professor in organic chemistry in a non-collegiate university many years ago. However, I work at the facility as a professor of biochemistry, my current area of expertise. Mind you, I do have a few organic chemists in my team who were lecturers and readers in organic chemistry in a previous life.
That information alone will assist in identifying me in academia, but without access to my academic CV, it's not possible otherwise. Comprehensive staff information is no longer disclosed on university faculty websites for various reasons. Furthermore, I've never disclosed my age on AB apart from saying I'm a grandparent, a pretty obvious disclosure given my career timeframe.
I really do try to leave it at that and I'm grateful to you for pointing out the risk. You are absolutely right.
Staff at this facility are forbidden from discussing or identifying colleagues outside the facility. Research papers are also forbidden from being published if the research involves the facility except in extreme circumstances. These measures in general, make staff identification next to impossible - a few months ago, I discovered my youngest daughter's boyfriend worked in another laboratory onsite and I had no idea!
A few years ago, a member of AB on a thread disclosed that he knew exactly who I was. Fortunately, he didn't mention my name on the thread. I thought nothing of it until I was sitting at home one evening and he telephoned my landline. It turned out I had indeed known him for years via my university, but it was a shock all the same. He had worked in a refectory. It was an educated guess on his part but he had made the connection and I was startled. Regretfully, he is no longer around on AB.
I do try my best to avoid jigsaw identification and I'm grateful to you for pointing out the dangers. Thank you.
