A former assistant professor is suing four Emporia State University officials, alleging he faced racial discrimination and retaliation before he was fired.

Rajesh Singh taught at the university’s School of Library and Information Management from 2009 to 2015. He is suing two current administrators in the department, a provost and the university’s former president. He plans to add the university to the lawsuit.

The lawsuit comes about a month after Melvin Hale, a current assistant professor in the same department, filed a defamation and invasion of privacy lawsuit against the university.

Singh, who is Asian, contends he was subjected to years of discrimination at the university, despite receiving outstanding reviews, and his efforts to argue his case were ignored.

Emporia State did not immediately reply to a request for comment.
