David F. Lambert, III, appeals from the district court’s order granting summary judgment in favor of his former employer on his claims alleging a hostile work environment and retaliation in violation of the Americans with Disabilities Act (ADA), 42 U.S.C. §§ 12101-12213 (2000). * We have reviewed the record and find that Lambert failed to establish a prima facie case of disability discrimination or retaliation under the ADA, see Fox v. General Motors Corp., 247 F.3d 169 (4th Cir. 2001); Freilich v. Upper Chesapeake Health, Inc., 313 F.3d 205, 216 (4th Cir. 2002). Accordingly, we affirm the award of summary judgment to the Defendant. We deny Lambert’s request for 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.

AFFIRMED
