Following allegations that he asked a Ph.D. student to omit data in order to manipulate research, Gregory Guisbiers, a professor at the University of Arkansas at Little Rock, has filed a defamation lawsuit against former advisee Matthew Kusper, arguing the accusations against him are false.
In April Kusper told local TV station KATV that Guisbiers asked him to “hide data” or use inappropriate samples as part of unspecified materials science research. Subsequently, Kusper said he confronted his adviser, severed ties and filed a complaint against him. An attorney for Kusper told the TV station at the time that both the university and several federal agencies had launched investigations against Guisbiers.
Now Guisbiers is fighting back with a defamation suit, KATV reported this week.
Guisbiers disputes the allegations Kusper made, arguing that he was a “problematic student” and a “very rude person” who was difficult to work with. Guisbiers said he never told any student to manipulate research data and that Kusper threatened legal action against him in 2020.
An attorney for Guisbiers told the TV station that Kusper has a vendetta against his client and has filed unfounded complaints with the Arkansas Ethics Commission and scientific journals, noting the complaint filed with the ethics commission against Guisbiers has been dismissed.
KATV reported that a hearing for the defamation suit has not yet been scheduled.
