No, I have not done research that related specifically to colonialism and indigenous people's interest in politics. However, I have taken an interest in related subjects.
In a study I co-wrote with Martin Papillon and Simon Dabin that was published recently, I measured the effects on indigenous people when they had the opportunity to vote for indigenous candidates in their ridings. We observed that it has a positive effect. It isn't about the effect of colonialism as a general concept, but I touched on it a bit, and we observed that there is a positive effect when indigenous voters have a chance to vote for an indigenous candidate.
I don't know what you mean, more specifically, when you talk about research, but I haven't published that kind of research.
