John Loike (born 1950 in Stockholm, Sweden) is an American research biologist and bioethicist at Touro University.

His articles have dealt with such issues as stem cells, cloning,[3] neuroethics, bioterrorism, and the interface of science and religion.

Many of these issues are hotly debated around the world, and specifically in Israel, where religious leaders have a big influence in public policy.

[citation needed] Serving on a Rabbinical Council of America panel on stem cell research, Loike highlighted scientific innovations that could allow for additional research, while alleviating the ethical questions posed by the scientific use of embryonic stem cells.

[4] In 1982, Loike and his longtime study partner, David Hurwitz, published a first-of-its-kind guide to Passover medications.
