Thank you Jamie_Wizard.

That's right as you said it's a team work which have been previously agreed and discussed earlier with my PI who should be part of the authorship of the experiment and any publication related to the corresponding experiment. That's why there names are in my abstract and in the poster as co-authors. Of course the new post doc name was not there at all (not even discussed as the post doc was not there).

So do you mean that the post doc name now can be inserted into any publication related to this experiment? Do you mean that if a post doc join a group this week, any publication in the group (which are already in the preparation) should now add the post doc name?

Thank you for your advices PhoenixFortune. I will discuss with my PI regarding this matter and the role of the new post doc.

Based on the draft of the abstract (considering that the post doc just modify my abstract), the post doc will most probably present the results of my PhD work (of course with help and support from my co-authors, in this case PI, current and previous colleagues).

The experiment was done with the help of my co-authors and the data was analyzed by me. Usually it takes few months to a year to analyze a single experiment. The post doc just joined the group and of course didn't have any contribution during the experiment, analysis or discussion.

The post doc so far only used my abstract. Nevertheless, considering that the post doc only write about my experiment, the post doc will definitely present my results (most probably by using what have been presented in my poster). Our group have a common server where everyone in the group has access to. The post doc may have access to my data, but may not make any changes.

Hi, I am in my third year of my phD. Due to up and down in my research and almost no supervision from my PI, I have not published my work and only presented a poster at few conferences.

A new post doc with no experience in the topic just joined our group this month. The post doc is quite new as the post doc just finished his/her PhD, worked some time and joined our group as a post doc. The post doc is planning to go for a conference next year. My PI asked me to send the post doc my recent abstract (from the conference I attended this year). So I send my abstract to the post doc and the next day the post doc sent his/her abstract to me and asked for my opinion and asked me to correct the abstract. The post doc just basically rephrashed, edited, resentenced, and added more sentences to my abstract and changed the title and used it as the post doc's abstract. The main work and the main content of the post doc's abstract will be still my work (which the post doc has not any contribution at all). The post doc put his/her name as author in the post doc's abstract and put the authors of my abstract (me and my co-authors) as co-authors (so basically pushing my first authorship and inserting the post doc name as the first author).

I was really upset with this matter and I have not responded to the email yet. I feel that all my hard works for the past 2 years have been stolen by a new post doc who joined and without experience at all.

Can a new post doc who didn't participate and has any contribution to my work presents my work at a conference? Can the post doc submit a edited version of my abstract to another conference and just insert the post doc name as the first author? What should I do as a PhD student with lower position in the group to protect my work?

I have never work with new post doc and I am not sure how I should treat the post doc. My PI is planning to handover the leadership of the project to the new post doc (so basically, I would be working under the new post doc). Could you advice me how should I do for the next year of my PhD? How should I treat the post doc?

I am planning to publish my work in the upcoming year and I would like to protect my work before it's published. Could you please give me your advices!
