ALBUQUERQUE, New Mexico — The University of New Mexico formally censured Tuesday a psychology professor after he tweeted that people battling obesity don't have the willpower to finish doctorate degrees.

In a statement, the school said Geoffrey Miller's work will be monitored by the psychology department chair and that he must apologize to his colleagues.

In addition, Miller won't be allowed to serve on committees involving graduate school admissions "for the duration of his time as a faculty member at UNM," the university said.

Miller wrote on Twitter last month that obese doctoral applicants who don't "have the will power to stop eating carbs" won't "have the willpower to do a dissertation." The tweet has since been deleted and his Twitter account has been made private.

He later apologized and said the tweet was part of a research project.

The university recently found the tweet wasn't part of any research project as he claimed.

Miller is on leave from UNM while serving as a visiting professor at New York University. He is scheduled to return to UNM this fall.

He did not immediately respond to an email from The Associated Press.

The university also said UNM Psychology Department Chair Jane Ellen Smith also investigated Miller's dealings with students and colleagues and "found no evidence Miller had discriminated against people who are overweight."
