Here are some Jainism-focused PhD / doctoral research topic ideas that would fit well in USA universities (Religious Studies, Philosophy, South Asian Studies, Anthropology, Ethics, etc.):

1. Ahimsa and Modern Bioethics

- How Jain principles of ahimsa and anuvrat can guide debates on animal testing, organ transplantation, end-of-life care, or veganism in the US context.

1. Jain Diaspora in North America

- Sociological study of Jain communities in the USA: temple-building, youth identity, language, interfaith activities, and preservation of vows in a non-Jain society.

1. Anekāntavād and Pluralism

- Comparative study of Jain anekāntavād / nayavād with modern ideas of religious pluralism, tolerance, and dialogue in American public life.

1. Jain Business Ethics in the Global Economy

1. Jain Meditative Traditions and Psychology

- Detailed study of Jain dhyān, prekṣā-dhyān, and pratikraman from a Jain scriptural perspective, and how they relate (carefully, without diluting Jain doctrine) to modern psychology and mental health research.

1. Comparative Study of Jain and Buddhist Ascetic Ideals

- Focus strictly on doctrinal, textual and historical comparison: vows, monastic rules, concept of liberation, karma theory, etc., using canonical sources.

1. Jain Karma Theory and Moral Responsibility

- Philosophical analysis of how Jain karma theory explains suffering, responsibility, and spiritual progress, and how this compares with Western ethical theories.

1. Women in Jain Traditions

- Study of the role, status, and spiritual path of Jain women (śrāvikās and sādhvīs), noting differences in Digambar and Śvetāmbara traditions, using texts and fieldwork.

1. Preservation and Digitalization of Jain Manuscripts

- Work on cataloguing, digitizing, and analyzing specific sets of Jain texts, with proper attention to traditional commentaries and their transmission history.

1. Jain Rituals in a Modern Context

- Detailed ethnographic study of rituals like pratikraman, samayik, Paryushan, Ayambil Oli, etc., as practiced in American Jain centers and how meanings are being translated for second-generation youth.

1. Jain Logic (Syādvāda / Nayavāda) and Analytic Philosophy

How to use these in USA universities

• Look for departments of Religious Studies, Philosophy, South Asian Studies, Anthropology, or Ethics.
• Check if any faculty members explicitly mention Jainism, Indian philosophy, or South Asian religions in their profile.
• Shape your proposal clearly as:

- rooted in Jain scriptures and traditional commentaries - addressing a contemporary or academic question that Western academia recognizes (ethics, pluralism, environmental studies, diaspora studies, etc.).
