I am a fresh medical graduate. I worked with a professor who harassed me sexually. Unfortunately, I was afraid to talk and also a little bit confused because I was an international visiting student at that time. I did a great job in his lab before he did that. He wrote for me a great letter of recommendation at that time. After he started to be unprofessional, I decided to leave his lab.
Since then, I was surprised that he published the preliminary results of the research as conference abstracts without putting my name as a co-author. However, he stated that I am an author in the recommendation letter, formulated the primary draft and helped in the lab experiments, data collection, and statistical analysis as well. I sent him an email to ask him about the papers’ progress but he did not reply.
My question is: Now I want to apply for a research fellowship and I am going to use his letter of recommendation. But he wrote my last name as my father's name, not the family name that I usually use in my applications. I do not feel comfortable to send him an email. I do not know if it will be a problem if there is a difference between my last name in the application and what he wrote. I also feel so bad when I found him published the papers in an international conference without mentioning my name and feel worse for not reporting him, deleting the message, and moving on to another lab.
