A female Ohio State student has accused a professor, whom she once dated, of stalking her.Paul Ponomarev, an associate professor of mathematics at Ohio State for the past 24 years, is scheduled to appear in court March 17.University Police arrested Ponomarev Feb.19 charging him with menacing by stalking. The student filed a police report claiming the 54-year-old professor was harassing her.Ponomarev pleaded innocent to the charges at his Feb. 20 arraignment. University officials placed Ponomarev on paid administrative leave for the remainder of the Winter Quarter, said Peter March, chairman of the mathematics department. Spring is Ponomarev’s off-duty quarter, March said.”We presume that will be enough time for the case to be settled,” March said. Because she worked in the College of Math and Physical Sciences, the student saw Ponomarev often. She told police that in January 1998 she accepted one of Ponomarev’s frequent requests to have coffee with him.The two began dating and continued their relationship through the late summer 1998.The student told police that in March 1998 the relationship began to get more serious. According to the police report, it was also about this time that she began to worry about Ponomarev being possessive of her.She said that Ponomarev questioned her about her activities and whereabouts. She told Ponomarev that she wanted to “lighten” the relationship, but nothing changed.The student told police she tried to end the relationship in August, and September, but Ponomarev continued to harass her.She said Ponomarev followed her to her car and blocked her from getting into it in September 1998. She also reported that Ponomarev called her 13 times that night.In January 1999, the student told police she began receiving phone calls and letters from Ponomarev again. She said that the ordeal came to a head Feb. 10 when Ponomarev confronted her on the Oval and chased her into a classroom building on West 18th Avenue.The student told police that because of the stress she has suffered, she quit her job in the math department and no longer attends some of her classes out of fear that Ponomarev knew her class schedule. Ponomarev is being represented by attorney Margaret M. Kirk. She did not respond to four messages left at her office Thursday.
