I have attached a link to an excel study of every US based law professor that teaches a class related to international law (broadly conceived), along with every other class they teach, a link to their profile, and their email contact, organized by state and school alphabetically. There are a few omissions.* The study, however, is by and large complete, and part of a much larger empirical based analysis of the law school industry. The motivation is to provide data and encourage new networks and communication among administrators and scholars within the legal academy, with the hope that these directions contribute towards better understanding of the law school market.
In this attached study, certain statistics and trends may be of interest. To a certain extent, international law remains potentially gendered: women make up only about a third of professors teaching classes related to the subject and over-represent the male colleagues when it comes to teaching ‘lawyering’ or courses on ‘gender’ or ‘children’. States average about 8 international law professors, with the highest number of professors per school in Connecticut and Washington, D.C., followed closely by Hawaii, Illinois, Massachusetts, New York, Oregon and Wisconsin, and at the lower end, states such as Rhode Island, North Dakota and Alabama – all in all, nothing surprising, though more evaluation could look into things like the ratio of ‘private’ / ‘public’ international law oriented classes. A word search of what most popularly shows up as the course title in a curriculum, words topping the list included, human rights (296), comparative (271), constitutional (251), and business (235), followed by words such as environment (121), intellectual property (109), international criminal law (91), and less common terms, such as religion (16) and critical race/legal studies (10). A relatively small percentage of professors teach first year courses (contracts: 161, criminal: 126, civil procedure: 102, property: 93, torts: 91), while certain courses (administrative law: 79) and words (transnational: 52, global: 73) seem to be trending upward. Further analysis could look into how courses are paired or the educational backgrounds and degrees of the community.

* Omissions, such as, the University of Pittsburgh School of Law, prolific international legal scholars such as Larry Cata Backer, and classes by law professors such as Justin Desautels-Stein.
