My partner is wanting to undertake her LLM at a leading American law school, specialising in law and public health. Harvard obviously has a prestigious school of public health at which it would be possible to do some papers.
What other schools are recommended in this field? I have seen the US News Rankings for the specialisation of healthcare law, but would appreciate any other views.

Definitely look at Emory University in Atlanta. I spent a year on exchange at the law school and I was thoroughly impressed by the faculty (not so much w/ Atlanta but thats another story). Top-tier law school and one of the best and well respected Public Health schools in the world. I know that there is a joint-degree program option for JD students between both faculties but i don't know of the possibilities for LLM students. Anyways its worth looking into...
