After completing my phd, my advisor changed his behavior with me, starting to keep a certain distance, avoiding conversations like the ones we had throughout the phd. About 6 months later, he intimidated me with a video call and then removed me from the position of first author of an article we were writing, one of the results of my thesis. About 10 months later he published the article without my name.
After about a year and a half of defending the thesis, he repeated this, expelled me from authorship for not agreeing to cite the first paper and another result of the thesis of other your student. Then he published a new article, also a result that emerged in the already published thesis of your student.
Prior to these two articles, he had published another result of my thesis hidden from me. But I found out and he was very angry with me, even offending me by email.
In this way, he stole the top 3 results of my thesis (perhaps the only ones at the publishing level directly), published they in high-impact journals in the field, intimidated me by email for the questions I asked when I was participating in the preparation of articles and acts like a gangster with his students, robbing and intimidating those who find out.
This fact occured (and currently ocurs) in Brazil, a country with a high history of corruption, in a renowned university, with a very influential professor in his area, but with several dubious scientific attitudes and postures. During the relationship I had with him, I identified other cases of abuse and improper attitude of he for his mentees.
I would like you to help me know how to proceed. Do you think it's worth going through local legislation, any international organization that can assess, or divulge his e-mails to the community with the threats and nonsense he said, and even expelled me from the authorship of the works?
Brazil is going through a difficult time in government, being very difficult to have a position as a researcher. I am thinking of continuing the research on my own, but I would not like to open up the results, nor let this be repeated for other researchers in this area. This greatly harms science, a posture like this is not acceptable, further in times as difficult as that of the pandemic and the current Brazilian government (a fascist that has greatly harmed science in Brazil).
