Not your credentials specifically, but Steven Quay. Cursory search suggest he's not an expert in relevant fields, but does have a book about lab leak theory. Immediately suspicious as there are a lot of scientists that turn to grifting in areas that were not relevant to their expertise.

I don't much care what the man does with his free time. I'm more interested in the veracity of his statements. On that front he supplies copious references to peer reviewed research by numerous others and primary sources. Character assassination is for folks who can't argue on the merits.

You still haven't offered your own credentials.
