Dr. Yoon, a stomach cancer specialist and a proponent of robotic surgery, kept climbing the academic ranks, bringing his junior researcher along with him. In September 2021, around the time the study was published, he joined Columbia, which
celebrated his prolific research output in a news release. His work was financed in part by half a million dollars in federal research money that year, adding to a career haul of
nearly $5 million in federal funds.
The decision by the stomach cancer study’s publisher, Elsevier, not to post an explanation for the paper’s removal made it less likely that the episode would draw public attention or affect the duo’s work. That very study continued to be cited in
papers by other scientists.
