I've just finished a Bachelor of Engineering with Honours. My academic supervisor submitted my honours research paper to a conference being held next year. In short: The extent of my supervisors contribution was approving my requests for purchase orders. I devised, built and ran the experiments at home. The first time he saw any of the work was when I handed in the paper for marking. A few days later, without my knowledge, he submitted the paper for the conference, the only changes were applying the required format style and adding his name as second author. I found out when I received an automated email stating I was a co-author on a paper submission. Had I known he was going to submit it I would've wanted to make a lot of improvements. I like my supervisor, and don't want to rock the boat (whether I get 1st class honours hinges on how he marks my other work..). I understand, in some areas, it's common practice for professors to add their name to an undergrads work to lend weight and increase the chance of publishing. However, If, on the off chance it was accepted, I'd feel a little disappointed that I'd be sharing authorship for something that is entirely my own work. Is this situation normal? Should I just wait and see if it's accepted or speak up now?
