Are there any programs where one can concurrently study towards a LLM and a PhD in philosophy or other related fields such as history, political science? There are a number of joint JD/PhD programs, but I am having trouble finding joint LLM/MA and LLM/PhD programs. If you are aware of a resource or program, please post!

If you search for "Other Degrees (Non-LLM)" in the Advanced LLM Program Search, you will find some joint programs LLM/MA programs, e.g. George Mason University (http://www.llm-guide.com/university/313).

George Mason University also offers a LL.M. / Ph.D. Joint Degree Program in Law and Economics.

You can also use the advanced search to search for "Dual Degree Programs"
