Consulting and Related Relationships

At The Ohio State University Wexner Medical Center, we support a faculty member’s research and consulting in collaboration with medical device, research and/or drug companies because a faculty member’s expertise can guide important advancements in the practice of medicine and improve patient care. In order to provide effective management of these relationships, the University requires annual disclosures from all faculty members with external interests related to their University responsibilities.

As of 10/25/2021, Dr. Chan has reported no relationships with companies or entities.
