Roland Onawola appeals the district court’s order dismissing this action on the basis of res judicata. We have reviewed the record and find no reversible error. Accordingly, we affirm for the reasons stated by the district court. Onawola v. Johns Hopkins Univ., No. 1:07-cv-00870 (D.Md. Sept. 24, 2007). We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
