Well, to begin with, you have the word genealogy in your topic, so maybe you would want to use that very method, Foucault's genealogy. If not, then it depends on which form of technique under qualitative method are you more comfortable working with. There are various techniques under this method. You could refer to Sage's handbook of qualitative research for further understanding of them. All the best! Cheers!
Dear Shuvechha, thank you for your response. Actually I would like to use Foucault's genealogy as my qualitative research method. However, as he has not developed method as such, I want to be in touch with some scholars with in-depth understanding of Foucault.
I have Sage Handbook of Qualitative research, and have gone through that. Now I want do develop methodology from Foucault's scattered ideas on archaeology and genealogy. So I need help from scholars. Do you know anyone who has used Foucault in his/her PhD research ?
