His research has focused on normative moral theory, including the concepts of goodness, desert, and virtue, and on articulating and defending a "virtues-based, role-centered, and patient-focused" moral theory, while critiquing consequentialist and other alternatives.
In the last decade, he has written an influential series of articles philosophically developing what he calls a "volitional" conception of racism, and he is currently arguing for a deflationary approach to race and ethnicity, and for narrow limits to what can be socially constructed.
He's addressed such bioethical issues as euthanasia, physician-assisted suicide, artificial nutrition and hydration, and ethnic perspectives on medical ethics.
Before coming to Boston College in 2000 as a tenured professor, Professor Garcia taught at Rutgers University (New Brunswick), Georgetown University, and at the University of Notre Dame.
