A doctor described as the resident physician to the twisted upstate sex cult Nxivm has been charged by a state oversight board with illegally conducting human experiments.

The action comes eight months after the state Health Department refused to act on a complaint from a former cult member who alleged that Dr. Brandon Porter, 44, forced her to watch disturbing rape and dismemberment videos for a “fright study” he was conducting.

Jennifer Kobelt, the former member of the notorious cult whose leaders are accused of brainwashing and blackmailing women into becoming sex slaves, said in her August 2017 complaint that Porter may have performed his “fright study” on as many as 100 people.

“He continued to film my reaction for at least 10 minutes as I just sat there, dry heaving like I was going to puke and crying very hard,” Kobelt, a Canadian actress, said in the complaint to the Health Department, adding that Porter began showing her the violent images without warning.

“He failed me, not only as a friend but as the medical practitioner I had trusted on numerous occasions with my health while I was in New York,” Kobelt said in the complaint.

In a Sept. 6, 2017, letter, the state Office of Professional Medical Conduct told Kobelt it would not investigate Porter, adding that “the issues you have described are not medical misconduct.”
