I did not sign 'Non-disclosure Agreement' (NDA). Never. With no one.

Some people try any fraudulent way to get my signature and  'Non-disclosure Agreement' (NDA).
I do not know why they need my signature and  'Non-disclosure Agreement' (NDA)? They have enough signatories.
Therefore, be careful.
Do not believe any of my signatures related to my professional activities! This is a forgery.
Sincerely,

Ph.D. Natalia Peterovskaya
