Catherine Nolan defended her dissertation, The Ethics and
Metaphysics of Vital Organ Donation, at SUNY Buffalo in 2015.
She is presently an affiliate associate professor at the University
of Dallas. She is interested in questions at the intersection of
metaphysics and bioethics. Her dissertation focused on the
definition of death and the impossibility of diagnosing it with
certainty in time to explant vital organs, concluding that it is
more practical to attempt to avoid causing death than to diagnose
Nolan's more recent research has been on the definitions of gender and sex, and she has recently presented “Metaphysical Positions for Trans Persons” at the PANTC 2016 conference, and is currently working on an article entitled “Difficult Determinations of Sex,” in which she proposes a definition of “male” and “female” which takes into account intersex individuals—those with disorders of sex development.
