A law professor at Notre Dame has decided to part ways with the university’s Lew Institute for Asian Studies due to the appointment of a new professor who openly supports abortion rights. Diane A. Desierto, in a statement, confirmed her resignation from her roles as Faculty Fellow and on the Faculty Executive Committee, submitting her decision to the university’s top officials.
In a separate correspondence, Robert M. Gimero, also a research professor emeritus, conveyed to the Lew Institute’s director his choice to step back following the same appointment. Osterman, who began her journey at Notre Dame in 2017 as a world affairs professor, is set to lead the Center for Asian Studies starting July.
Zimero expressed disappointment in his resignation letter, noting the contrasting beliefs Osterman has towards the Catholic teachings on life. His insistence that the university’s basic religious tenets should be upheld was clear; he deemed it untenable to remain associated with an institute under leadership that diverges so sharply from those principles.
Moreover, he voiced concerns that Osterman’s appointment might blur the lines of Notre Dame’s commitment to its Catholic identity for those outside the institution. Reflecting on the role of dialogue about life and ethics in Asia, he argued that the university needs to present a consistent Catholic viewpoint while engaging with Asian scholars and institutions.
The university has reiterated its support for Osterman, emphasizing her qualifications and the continuous professional courtesy extended to Zimero, who has not been involved with the Liu Institute since his retirement in 2017. Meanwhile, Fox News Digital has sought comments from Osterman regarding the situation.
