I study a very specific population of indigenous people. During grad school, my adviser applied for a grant which allowed us to put together a large dataset that focuses on individuals from this specific population.
I thought we had picked the dataset clean but recently returned to the dataset and found evidence for a new idea I have been pondering.
I would like to publish a study but dont want my adviser as an author on the paper since I am trying to establish greater independence as a junior professor.
My question is this: Is it wise to ask my former adviser if would be okay with me leaving him out as an author? I would ofcourse reference his grant and simply call it a secondary data analysis on an existing dataset.
Assuming my adviser says yes, is this frowned upon in academia?
