Fr. Pacholczyk currently serves as Senior Ethicist at the NCBC. A priest of the Diocese of Fall River, Massachusetts, he has given several hundred presentations and participated in debates and roundtables on contemporary medical ethics and bioethics throughout the United States, Canada, and Europe.

Fr. Pacholczyk has degrees in philosophy, biochemistry, molecular cell biology, and chemistry. He later earned a PhD in neuroscience from Yale University, where he focused on cloning genes for neurotransmitter transporters which are expressed in the brain. After working for several years as a molecular biologist at Massachusetts General Hospital/Harvard Medical School, Fr. Pacholczyk studied in Rome at both the Gregorian University and the Lateran University, where he did advanced work in dogmatic theology and bioethics, examining the question of delayed ensoulment of the human embryo.

He has testified before members of the Massachusetts, Wisconsin, Virginia and Oregon State Legislatures during deliberations over stem cell research and cloning. In 2020, he was appointed to the National Institutes of Health Fetal Tissue Research Ethics Advisory Board. He writes a syndicated monthly column on bioethics that appears in more than forty US diocesan newspapers as well as newspapers in England, Poland, and Australia. He has appeared in numerous media outlets, including NBC, ABC, CNN International, National Public Radio, the Wall Street Journal, the Dallas Morning News, and the New York Times.
