RICHARD L. VOORHEES, District Judge.
Because neither party has objected to the Magistrate Judge's statement of the factual and procedural background of this case, the Court adopts the facts and procedural background detailed in the M&R.
The Federal Magistrate Act provides that a court may "designate a magistrate judge to conduct hearings . . . and to submit . . . proposed findings of fact and recommendations for the disposition [of dispositive motions.]" 28 U.S.C. § 636(b)(1)(B). "[A] district court shall make a de novo determination of those portions of the report or specific proposed findings or recommendations to which objection is made." 28 U.S.C. § 636(b)(1); Camby v. Davis, 718 F.2d 198, 200 (4th Cir. 1983); accord Fed. R. Civ. Pro. 72(b)(3). "By contrast, in the absence of a timely filed objection, a district court need not conduct a de novo review, but instead must `only satisfy itself that there is no clear error on the face of the record in order to accept the recommendation.'" Diamond v. Colonial Life & Accident Ins. Co., 416 F.3d 310, 315 (4th Cir. 2005) (quoting Fed. R. Civ. P. 72, Advisory Committee Note).
Under Rule 72(b) of the Federal Rules of Civil Procedure and 28 U.S.C. § 636(b)(1), a district court judge shall make a de novo determination of any portion of an M&R to which specific written objection has been made. A party's failure to make timely objection is accepted as an agreement with the conclusions of the Magistrate Judge. See Thomas v. Arn, 474 U.S. 140, 149-50 (1985). No objection to the M&R having been filed, and the time for doing so having expired, the parties have waived their right to de novo review of any issue discussed in the M&R.
Furthermore, the Social Security Act provides that the "findings of the Commissioner of Social Security as to any fact, if supported by substantial evidence, shall be conclusive." 42 U.S.C. § 405(g). Judicial review of the Commissioner's final decision regarding disability benefits is limited to determining "whether the findings are supported by substantial evidence and whether the correct law was applied." Walls v. Barnhart, 296 F.3d 287, 290 (4th Cir. 2002). The reviewing court should not "undertake to re-weigh conflicting evidence, make credibility determinations, or substitute [its] judgment for that of the Secretary." Mastro v. Apfel, 270 F.3d 171, 176 (4th Cir. 2001) (quoting Craig v. Chater, 76 F.3d 585, 589 (4th Cir. 1996)).
After a careful review of the record in this case, the parties' briefs, and the M&R, the Court finds that Judge Keesler's M&R is supported by the record and is consistent with and supported by law. Finding no clear error in either the Commissioner's final decision or the M&R, the Court
