Having Trouble Finding a Faculty Member for Math Undergraduate Research
I'm going to suggest that you take a different approach, for now.


When you visit or email a researcher, start by reading some of his or her writing.  The start the conversation by speaking about the article you read.  Mention something you found interesting or well explained.  Ask a question about something you didn't understand.  If necessary ask for some recommended background papers.  Ask a question about future directions.  Then ask the researcher what s/he is working on currently.  Be a good listener.
Keep a notebook of project ideas.  Put your current project in this notebook.
Ask each professor you visit if s/he has any projects to offer for summer.  Listen carefully to the project description.
