[citation needed] He holds a lifetime appointment as distinguished affiliated professor at the Technische Universität München (TUM), in Munich, Germany, where he is affiliated with its Hochschule für Politik and he teaches annually as Non-Resident Professor at the Florence School for Transnational Governance at the European University Institute in Firenze, Italy.

[19] Regarding international relations theory more generally, Moravcsik adheres to "liberal" theory in the sense that he seeks to explain state behavior with reference to variation in the underlying social purposes (substantive "preferences" or "fundamental national interests," material or ideational) that states derive from their embeddedness in an interdependent domestic and transnational civil society.

To this end, he has proposed the use of "active citation" the use of precise footnotes hyperlinked to source material contained in an appendix or on a permanent qualitative data repository.

[28] He has lectured about the European Union at The Pentagon,[29] was a guest on NPR's Talk of the Nation,[30] and has been quoted in multiple news sources, including Deutsche Welle,[31][32] International Herald Tribune,[29][33][34] and USA Today.

He continues to engage in regular policy analysis and advising, currently focusing on EU–US burden-sharing, the democratic deficit in Europe, transatlantic relations, the future of the European Union, and Asian regionalism.

He has also written and spoken for The Atlantic and other media outlets on the desirability of men serving as the "lead parent" for children and playing an equal or more active role in caring work.

[38] His father, Michael Moravcsik (1928–1989), was a Hungarian immigrant to the United States globally active as a professor of theoretical particle physics, an expert on science development, and a pioneer in the field of citation studies.

His great-grandfather, Sándor Fleissig, was a Hungarian banker and public official who served as president of the Budapest Commodity and Stock Exchange.

Moravcsik's mother, Francesca de Gogorza, comes from a New England family of Basque, Hispanic, Dutch, German, Scottish, English and Native American ancestry.

Moravcsik is married to the legal academic, political scientist, public intellectual, university administrator, government official, and think-tank director Prof. Anne-Marie Slaughter, with whom he has two sons.
