The thesis topic and this summer's paper

Although I have now lost my supervisor for my thesis on retaining the knowledge of the baby-boom I am still committed to giving a paper as though my thesis topic has not changed and is going ahead. This leaves me out though because I am now a student with a topic searching out a supervisor. This seems a weaker position. I will now need to contact all the potential supervisors on the program's list for someone who can agree to take my topic and me on.
