For anyone who may be interested....A few years ago I connected to Linkedin, but I do not use this web site for anything. I seek no endorsements and do not provide them any more because I believe it is just a list of friends who wish you well, not a valid predictor of competence.I do entertain professional consulting and expert witness opportunities in the health policy field, so I am "open for business." However, I suspect that suitable projects will come my way by reputation and word-of-mouth from satisfied clients, rather than exaggerated claims on a public web site.
