Expertise Validation: A Response to a Research Inquiry

Question
What exactly makes you an expert Tom?  I'm not asking to question your expertise but to cite you as an expert on a paper I'm currently working on.  

Answer
Heather, while I have no official degrees or certificates in the subject, I do give lectures and debate the issue.  My expertise comes from this and following the trends in the bioethical arena for the last 6 years.  If you needed any specific information, just ask again and mark the question private.
