MEMORANDUM OPINION AND ORDER
SUSAN RICHARD NELSON, District Judge.
I. INTRODUCTION
This matter is before the Court on Plaintiff's Motion to Strike Defendant's Discrimination Expert [Doc. No. 226]. For the reasons set forth below, the Court denies Plaintiff's motion.
II. BACKGROUND
The specific details of this employment discrimination action are documented in other orders and will not be recounted here. (See, e.g., Jan. 26, 2012, Mem. Op. & Order at 2-4 [Doc. No. 18].)
After this litigation began, Defendant retained Benjamin Shippen, Ph.D., as an expert to review the salary decisions in 2008 for two positions at the Honorary Norwegian Consulate General: the Higher Education and Research Officer position ("Higher Education position") and the Innovation and Business Development Officer position ("Innovation position"). (Expert Report by Benjamin S. Shippen, Ph.D., Ex. 3 to Aff. of Thomas E. Marshall [Doc. No. 227-1].) Specifically, Dr. Shippen was asked to determine whether the salary decisions were consistent with the compensation for similar positions in the general geographic area of Minneapolis, Minnesota, where both positions were located. (Id. at 1.) After reviewing various documents and data,1 Dr. Shippen concluded that
substantially different skills, backgrounds, and experience were required to perform these two jobs. These were qualitatively different jobs, each demanding unique qualifications and requiring vastly different sorts of professional experience. A review of the labor market compensation data shows that occupations with job requirements and duties most like those of the Higher Education position are not similarly compensated compared to occupations with job requirements and duties most like those of the Innovation position.
(Id. at 3.)
Plaintiff moves to strike Dr. Shippen as an expert for Defendant, arguing that the expert opinion is inadmissible at trial because Dr. Shippen: (1) does not consider the facts of the case, and (2) arbitrarily categorizes occupations based on speculation and conjecture. (Pl.'s Mot. to Strike Def.'s Discrimination Expert at 16-25 [Doc. No. 226].) Defendant responds that Plaintiff's motion is not properly before the Court. (Def.'s Mem. of Law in Opp'n to Pl.'s Mot. to Strike at 1-2 [Doc. No. 248].) Defendant also argues that Plaintiff's motion should be denied on the merits because Dr. Shippen's report and testimony are admissible, and Plaintiff's criticisms are unfounded. (Id. at 2-7.)
III. DISCUSSION
Federal Rule of Evidence 702 governs the admissibility of expert testimony. Under Rule 702, proposed expert testimony must satisfy three prerequisites to be admitted. Lauzon v. Senco Prods. Inc., 270 F.3d 681, 686 (8th Cir. 2001). First, evidence based on scientific, technical, or specialized knowledge must be useful to the finder of fact in deciding the ultimate issue of fact. Id. Second, the proposed witness must be qualified to assist the finder of fact. Id. Third, the proposed evidence must be reliable or trustworthy in the evidentiary sense, so that if the finder of fact accepts it as true, it provides the assistance the finder of fact requires. Id. These requirements reflect the Supreme Court's analysis in Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993). Id. The district court has a "gatekeeping" obligation to make certain that all testimony admitted under Rule 702 "is not only relevant, but reliable." Daubert, 509 U.S. at 589.
Nonetheless, "Rule 702 reflects an attempt to liberalize the rules governing the admission of expert testimony," and it favors admissibility over exclusion. Lauzon, 270 F.3d at 686. Doubts regarding the usefulness of an expert's testimony should therefore be resolved in favor of admissibility, United States v. Finch, 630 F.3d 1057, 1062 (8th Cir. 2011), and gaps in an expert witness's qualifications or knowledge generally go to the weight of his testimony and not its admissibility. Robinson v. GEICO Gen. Ins. Co., 447 F.3d 1096, 1100 (8th Cir. 2006). "The exclusion of an expert's opinion is proper only if it is `so fundamentally unsupported that it can offer no assistance to the jury.'" Wood v. Minn. Mining & Mfg. Co., 112 F.3d 306, 309 (8th Cir. 1997).
Applying this test to Dr. Shippen's proffered expert opinion, the Court first finds it to be relevant. Plaintiff offers no substantive argument to the contrary. Dr. Shippen's report and proposed testimony are relevant to Defendant's affirmative defense to Plaintiff's Equal Pay Act claim—that there were different salary markets for the Higher Education position and the Innovation position.
Second, the Court finds that Dr. Shippen is qualified to offer his opinion in this case. Plaintiff does not question Dr. Shippen's qualifications. Dr. Shippen is a labor economist with a Ph.D. in economics, and his fields of interest include labor economics, computer analysis of large databases, and applied econometric and statistical analysis. (Shippen Report at 20 [Doc. No. 227-1].) Since 2000, he has worked as an economist at ERS Group, where he is currently a Principal. (Id.) Such qualifications are sufficient.
Third, the Court considers whether Dr. Shippen's opinion is sufficiently reliable. Courts analyze reliability from a flexible, case-specific standpoint. Kumho Tire Co. v. Carmichael, 526 U.S. 137, 150 (1999). Because the Higher Education position and the Innovation position were created in 2008 and had no previous salary history, Dr. Shippen looked for comparable occupations. (Shippen Report at 2-3 [Doc. No. 227-1]; Decl. of Benjamin S. Shippen, Ph.D. ¶ 2 [Doc. No. 249].) To find comparable occupations, Dr. Shippen relied on: (1) the job descriptions for the Higher Education position and the Innovation position; (2) the job histories of the interviewed applicants for each position; and (3) the self-drafted activity reports of Plaintiff and Davidson. (Shippen Report at 1-3 [Doc. No. 227-1]; Shippen Decl. ¶ 5 [Doc. No. 249].) Dr. Shippen then used this information to compare the Higher Education and Innovation positions with similar occupations under the United States Bureau of Labor Statistics Standard Occupational Classification. (Shippen Report at 14-15 [Doc. No. 227-1]; Shippen Decl. ¶ 5 [Doc. No. 249].) Defendant represents that this methodology applies accepted labor economic analysis to this case. (Def. Royal Norwegian Embassy's Mem. of Law in Opp'n to Pl.'s Mot. to Strike at 4 [Doc. No. 248].)
Plaintiff challenges Dr. Shippen's alleged failure to consider all relevant facts, such as the discussions between Gary Gandrud and the Embassy regarding the setting of the salaries, the directions that the positions collaborate or work as a team, the statement by Gandrud and Walter Mondale that the pay disparity was "unjust and embarrassing," and the depositions of Davidson and Gandrud. (Pl.'s Mot. to Strike Def.'s Discrimination Expert at 19 [Doc. No. 226].) The factual basis of an expert opinion, however, goes to the credibility of the testimony and not its admissibility, and "it is up to the opposing party to examine the factual basis for the opinion in cross-examination." Bonner v. ISP Techs., Inc., 259 F.3d 924, 929 (8th Cir. 2001). Plaintiff will have ample opportunity to cross-examine Dr. Shippen. See Daubert, 509 U.S. at 596 ("Vigorous cross-examination, presentation of contrary evidence, and careful instruction on the burden of proof are the traditional and appropriate means of attacking shaky but admissible evidence.").
Plaintiff also criticizes Dr. Shippen's report for arbitrarily selecting a subgroup of applicants from the applicant pool for each position, in order to reach a pre-determined conclusion. (Pl.'s Mot. to Strike Def.'s Discrimination Expert at 19-23 [Doc. No. 226].) Defendant, however, represents that Dr. Shippen focused on the candidates who were interviewed for each position, because the background, skills, and experience of the candidates chosen for interviews reveal what Defendant viewed as necessary for each position. (Shippen Report at 6 [Doc. No. 227-1]; Shippen Decl. ¶ 11 [Doc. No. 249].) Regardless, the Court views Plaintiff's criticism primarily as a challenge to the factual basis for Dr. Shippen's analysis—not to the evidentiary reliability of the report. As mentioned earlier, Plaintiff can identify any weaknesses in the factual basis of Dr. Shippen's opinion by cross-examining this expert. Thus, the Court is satisfied that, for purposes of the Daubert standard, Dr. Shippen's opinion is sufficiently reliable.
Because the Court finds Dr. Shippen to be a qualified witness whose proffered opinion is relevant and reliable, it denies Plaintiff's Motion to Strike Defendant's Discrimination Expert. Plaintiff will be permitted to challenge Dr. Shippen's conclusion, as well as the factual basis for his conclusion, through vigorous cross-examination. IV. ORDER
Based on the foregoing, and all the files, records, and proceedings herein, IT IS HEREBY ORDERED that:
1. Plaintiff's Motion to Strike Defendant's Discrimination Expert [Doc. No. 226] is DENIED.
