    Filed: Sept. 17, 2015.
    Mauricio Rueben, Forrest City, AR, pro se.

   PER CURIAM.

Federal inmate Mauricio Rueben appeals the district court’s adverse grant of summary judgment in his action under Bivens v. Six Unknown Named Agents of Federal Bureau of Narcotics, 403 U.S. 388, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971), and the Federal Tort Claims Act (FTCA). Having conducted de novo review, see Peterson v. Kopp, 754 F.3d 594, 598 (8th Cir.2014), we conclude that summary judgment was warranted for the reasons explained by the district court. Specifically, as to the Bivens claims, some defendants were entitled to absolute immunity as Public Health Service officers, see Hui v. Castaneda, 559 U.S. 799, 811-12, 130 S.Ct. 1845, 176 L.Ed.2d 703 (2010); other claims were barred by sovereign immunity, or were improperly based on supervisory rather than individual liability, see Buford v. Runyon, 160 F.3d 1199, 1203 & n. 7 (8th Cir.1998); and yet other claims failed for lack of evidence -that Rueben’s serious medical needs were deliberately disregarded, or because defendants were entitled to qualified immunity based on the evidence, see Estelle v. Gamble, 429 U.S. 97, 104-07, 97 S.Ct. 285, 50 L.Ed.2d 251 (1976); Sheerer v. Stephens, 50 F.3d 496, 496-97 (8th Cir.1994) (per curiam).

As to the FTCA claim, the district court did not abuse its discretion in denying the request for appointment of a medical expert, see U.S. Marshals Serv. v. Means, 741 F.2d 1053, 1059 (8th Cir.1984); and Rueben did not otherwise provide expert testimony on medical malpractice, see Ark. Code Ann. § 16-114-206; Goodman v. United States, 2 F.3d 291, 292-93 (8th Cir.1993) (affirming dismissal of FTCA action due to lack of expert testimony on medical malpractice as required under state law). Accordingly, we affirm. See 8th Cir. R. 47B. 
      
      . The Honorable D.P. Marshall, Jr., United States District Judge for the Eastern District of Arkansas, adopting the reports and recommendations of the Honorable Jerome T. Kear-ney, United States Magistrate Judge for the Eastern District of Arkansas.
     
      
      . Language requiring that expert testimony be provided "only by a medical care provider of the same specialty as the defendant” was held unconstitutional in Broussard v. St. Edward Mercy Health System, Inc., 386 S.W.3d 385, 390 (Ark.2012).
