In an email statement to The Cavalier Daily, University spokesperson Brian Coy said the committee dismissed Bhattacharya because he violated the School of Medicine’s professionalism standards.

“The student in question was dismissed from the School of Medicine after a series of incidents and repeated instances of erratic behavior that raised security concerns as well as questions about his professionalism and fitness to practice medicine,” Coy said. “Claims that he was dismissed because he exercised his First Amendment rights are baseless, as the facts will show.”
